The butt-dyno felt no power gains. Ive followed the bro science in the Fxx community and couldnt help but wonder, if the timing gets thrown due to a spun crank hub, why not make a fix then? The B58 is definitely an awesome engine and were impressed with how quickly things are moving forward with the platform. Outside of that, meth definitely has some great performance benefits. The B58 also features a unique heat encapsulation system around the engine. Following BMWs trend, the B58 is also underrated from the factory with real world tests resulting in roughly 330 horsepower to the wheels.

Thanks Zach! Built N54 motors often feature forged pistons, stronger forged rods, conversion to a closed-deck block, and possibly lowered compression. I've got a 1986 merc 300sl that runs like a sowing machine. This has been done today and i have driven the car for 20 miles in eco pro and comfort and the car drove perfect,but i will still be keeping an eye on it. Reliability scores the highest marks compared to the N54, N55, and S55. or these are minor for this strong engine? Too much trouble. Excessive oil consumption is another big one that can alert you to this issue. Maximum PSI seems to make a good one. Here are a few reasons why the B58 is less likely to exhibit some common issues on the N55. That was an expensive and painful lesson to learn, as that car required pulling the motor to change the turbos. Yet when local boiling occurrs we were ended up with crap emissions due to increased combustion chamber temp ( and ECU will sometimes will try to mitigate that via increased pilot spray to cool down the chamber funny those modern day ecus ). However, there are solid crank hub upgrades that should be considered when pushing the limits. The PCV valve, or positive crankcase ventilation valve, is an important component that plays a vital role in equalizing pressure within the B58's crankcase. We appreciate the positive feedback. Dinan offers stuff thats covered under warranty. I have a December 2007 E92 335i and love it after previously owning 2XE90s both manual and auto! Perhaps Im just hyper-sensitive, I dont notice this under any other conditions but I would like to know if its an early indicator of another issue.. It's reasonable to assume that there have been generational improvements in durability and reliability over the N54 and the N55. *Picture is from an N54 that had a leaking VCG for nearly 20,000 miles. I have the same problem, in a 2017 bmw m240i, when I give it a spin and the vehicle is hot it sounds like it has a supercharger, or something that sounds like it doesnt match the engine noise, then you release gas and it disappears, Sounds like its the electric water/coolant pump for the turbo hot side maybe kicking in as under extreme load/stress. Im looking for my first sports car and BMWs seem very nice. Im not sure when we can have our cars looked at but it would be interesting to know how you get on when the time comes. VANOS is BMW's terminology for VVT, or variable valve timing. My regret (not even a problem) was that when moving from E to F, BMW matched gearboxes and diffs more closely to stock engine torques, which in my mind was a bit of step back, because you could always count on 3 things with BMW gearboxes in the past 1. they did not provided greatest feedback 2. they always had decent of headroom potential tune 3. every-time you changed gear you felt like you reloaded WW1 full caliber rifle. Many issues with their turbo engines. Could you give me some advice about this problem? Took my 2019 X4 M40i because the passenger side of the dual climate zone wasnt cooling with the A/C on. Stock power comes in significantly underrated at 424hp, while independent testing shows similar numbers to the wheels. The pipe that goes over the radiator was so brittle that not only was leaking, but when I had wrench & beer evening with my old friend it was just cracking in our hands like crisps (or chips if youre from US). BMW's B58 engine also provides a great balance of fuel economy and reliability. Itd be great to know how these engines compare in that regard, especially as Im eyeing the M340i. Thats really hard to put a number on since it can vary so much. Compared to the two former engines the N55 has been on the road longer, allowing for additional time for tuning developments. Automotive Performance, Tuning, & Modification. Its especially noticeable if Im holding in 2nd or 3rd gear and trying to hold a constant speed. Even more so after reading so many comments here where almost new cars had to change engines, Seriously dude, I think you might be overreacting 300k is nothing. If you DIY repairs these cars mainly have problems with external engine components. Im impressed to say the least. The B58 uses two coolant tanks in its system. I couldnt imagine them using it if there was in fact an issue. Expect B58 solenoid issues to arise around the 80,000-100,000 mile mark. About other part of your comment. The car seems to have lost some pep. Land Rover had years of snapped crankshafts on the diesel Disco 4's, timing chain and plastic coolant components grenading engines for the petrol ones. Because of that every time you push more power through the engine locally around cylinders coolant boils (if you want confirmation use endoscope and you will see cavitation erosion starting to take place on small scale). Just go hard more. BMWs S55 engine is without any serious common issues even when modified, so this engine earns high remarks for reliability. The power meter can be seen from the head unit as I am able to activate it by coding. Flush out and refill coolant every 5 years. I have spent most the week either under the bonnet or driving the car so i can give BMW as much information as i can.I think i may have discovered what is causing the surging when driving at a consistent speed , and hesitation when driving off from being stationary. Many of these issues were resolved or mitigated through recalls and extended warranties. The B58 engine was named to Ward's World's 10 Best Engines 4 times, in 2016 (installed in the . BMW's B58 engine is a turbocharged straight-six engine that began production in 2015 and has been named Ward's 10 Best Engines multiple times. Im not sure how many as I was never given any job sheets. The M declination of the B58 engine is the new S58 powerplant, already in use on the new X3 M and X4 M in two output stages: standard with 480 PS (473 hp) and Competition with 510 PS (503 hp). BMW B58 Reliability. Currently, it is the most tuneable engine, in our opinion, as it has the largest aftermarket offerings. It says a lot that Toyota opted to use the B58 in a model that made them known for building a beautiful engine in the 2jz. f34 130k miles (tuned about 30% up only intercooler upgraded) How do the BMW N54, N55, B58, and S55 stack up against each other? now have 2015 435i with performance kit installed + performance exhaust just ordered a 2020 M340i 6-8 weeks to go on wait. Did BMW live up to that reputation? (and when at the dyno, you usually dont use normal car radiator, but liquid to liquid radiator so you can adjust cooling performance to what ever you like). It also comes down to each specific engine. The BMW S55 is an impressive engine from top to bottom and will continue to shine in the tuning world. Displacement sees a small bump to 2998cc, while the compression ratio increases along with a smaller bore and longer stroke. Reliability + performance. This engine was manufactured by BMW in 2015 and was still in use. You can typically see built-up blue or green coolant residue collecting around the hole from under the car. Ever since the twin turbo N54 hit the markets in the 2007 BMW 335i, BMW has been building on the design of the turbocharged, direct injected inline 6 engine. Although, VANOS work can be done without lifting the engine. Some just keep looking at the past with rose tinted glasses. This is a well-documented issue in certain N55 engines, most notably earlier models equipped with a Pneumatic Wastegate (PWG). Just purchased a 2021 M340. Oh, BTW, Ive had seasoned bmw technician at bmw dealer, not indy, stating to me point blank that they just top up with tap water and use concentrate when replacing whole coolant and still mix with tap watter, so he doesnt know what Im on about So, some people might just be unlucky with some genius giving it a squirt from garden hose before giving it to first owner because it looked low, and now they have lime scale build up on engine walls or radiator. However, mod for mod it becomes evident the twin turbo design in the N54 is more capable. From day one of delivery, I have often smelled coolant. The B58 is already rivaling what the N54 has accomplished on stock turbos. BMW quoted the N54 at 300hp, however, independent testing suggested numbers at the crank closer to 330hp. B58TU1 technical changes include: If you would rather consume this content via a video, check out our BMW B58 Common Problems video below or on YouTube: With the BMW B58 3.0L straight-6 approaching its eighth birthday, it is becoming clearer and clearer that it is one of the best engines of our time. Now I still experience a bit of coolant loss, but much, much less. If so, thats impressive. Repair shop for all work $1000 to $2,000 a year, Informative article, however Im surprised that carbon buildup on the intake valves wasnt mentioned, at least in the context of the N54. Im experiencing the same as you when the car is under load. Why? We appreciate the input and you bring up some potentially valid points. Im guessing something might be coming up in future Im not sure if any other b58 owners have this or if its common Pistons are not forged, however they're pretty strongBlock Design: Closed DeckRedline: 7500Injectors: Bosch solenoid style direct injectors. Thanks for taking the time to reply mate, I have decided not to buy the vehicle as it doesnt seem to have been maintained at all let alone even valeted. Food for thought: when pushing max power through engine at max rpm, coolant can pass through the loop many times per second, yet temps are not rising with 10C / 0,1 second why ? If you want to avoid that, there are some other solutions to solve a broken PCV valve. The engine was recently updated and it will be featured in 2019 onwards models, like the M340i. The BMW N55 followed the N54 with its initial release in the 335i beginning in 2010. AND BTW, I dont know whenever new caps will fix anything. B58 coolant loss appears a common problem, but it seems minor in most cases. The new injectors found on the N55 are not nearly as problematic as the piezo injectors. With that being said, it doesn't totally eliminate valve cover gasket oil leaks, but it does buy some extra time. I had the 4.2 I6 in both my 1975 Landcruiser (FJ40) and my 1978 Jeep CJ-7. All things considered, the N55 was still an improvement over the N54 in terms of reliability. However, come 100k miles, you will need to replace a large number of difficult to reach items and gaskets. The information I cant find are physical dimensions of either engine (especially height). Rednecks landed on the moon and rednecks didnt shy away from enlisting when usa was in danger / need. We use cookies to improve your experience on our website. The B58 is more reliable than the N55. . in. Guess where the VANOS components reside? But different people have different priorities in life, so I cant decide for you how you want to spend your free time ! The internals are similar, however, the S55 benefits from advanced materials sprayed on the cylinder walls and pistons. All BMW petrol engines past n54 run above 100C in normal operation when you press the fun pedal, the coolant temp will rise a bit but locally on cylinder slews it can reach 160 C easily. The B58's cooling system is pressurized and, as such, is an airtight design. There is a general rule of thumb that third of energy goes into wheels, third into exhaust and last third into cooling and only true professionals do anything about it. Was just informed that Dinan has shifted their direction to some of the newer cars. Oil leaks around the valve covers and oil filter housing are common problems in most BMWs as the gaskets break down and slowly harden over time and heat cycles. Thank you for the comment. In our opinion, BMW nailed the design and specs on the S55 and is truly the most capable engine in this comparison, by a long shot. Anyone here want to offer an opinion? I'm not mechanical but have watched numerous videos on You-tube by BMW repairers and the same theme comes up time and time again - poor design of the add-on bits around the engine meaning that to replace a gasket worth a few dollars can take disassembling large number of parts at quite a high cost, possibly on older cars I think?. e92 168k miles (tune about 30% up) As a continuation of the N54 and N55 formulas, the B58 has proven that it is the more dependable engine as a whole. Guessing you are all semi-auto owners.. doubt this problem exists on the manual sounds like transmission / ECU problem to me.. #. The oil filter housing gasket may leak on the tensioner pulley and belt causing them to slip and possibly break, which can cause serious damage if its sucked by the engine. Would a swap to s55 be ruinously expensive and difficult? Enjoy your new B58! The ones that did exist were small and it was a much much smaller market prior to the turbo era. *Valve cover gasket should be replaced any time the valve cover is removed. Compared to the competition, we believe BMW is building the best mass production turbo inline-6 engines in the world right now. hopefully BMW will sort this out. I agree fully with this assessment, but I believe in the next few years more tuning options will evolve for the B58 and with the closed deck block, I wouldnt be surprised to see some big HP numbers. Replace the accessory belt every 80,000 miles. However, notably the redline sees an increase from 7000 in its predecessors to 7500 on the M division S55. ansolutely thrilled. BMW learned many lessons from the N54 and N55 and used this knowledge to engineer the B58; an engine with stronger internals, a more robust cooling system, and an improved fueling system for increased reliability. My car is going in to BMW on Thursday. Car done 150k now, and pipes that I replaced are still right colour, original coolant pump still works OK and I have zero issues with overheating and coolant temp when idle fluctuates at 110 117 C. From what Ive seen at the dyno where some inexperienced or know better then the test schedule requirements technician used pure water for cooling on endurance or long term emission tests, cooling pump seals and joint between shaft and plastic prop would fail first but on my car it was not the case so far, so as usual T&C applies, your milage may vary. I imagine a lot of (even most?) Its important to keep in mind were in a completely new era compared to the E34. Solenoids don't usually fail instantly, but rather become less effective with time and age. Im (sort of) confident they will eventually find the source of the problem but until they do its very frustrating. Any input apreciated. Nonetheless, you must pay to play and the N54 is no exception. Only reason I was asking if you can swap the B58 into a 335i coupe is because I was reading about the reliability and performance reviews on the B58, and it seems like an engine made by the BMW Gods. Cant wait to compare the BM3 to the Dinan Stage 1. Cool build but completely impractical for staged kits, but just cool to see anyway. It does not have signs of issues with any of its internal components. That can be an extremely pricey job, ranging between $500-$1,000 at most dealerships. The M340i is a beautiful car and the B58TU is a great engine. Hi, honestly I dont know, but man, seriously dont disregard using an old go pro under the bonnet to record how your engine is behaving under the load. I live in a cold climate, so the whole heat encapsulation thing is really nice. Copyright 2021 - 2023 BMW Tuning LLC. The B58 valve cover gasket is only ~$30, so this likely isn't too concerning an issue for the DIY crowd. A few recalls and service bulletins do exist for the B58. )Displacement: 2979cc (2.979L)Turbocharger: Twin turboCompression: 10.2 to 1Bore x Stroke: 84.0mm (3.31) x 89.6mm (3.53)Internals: Forged crank and rods. Our 440i is about 5 months old and has a little over 6000 Km. owners dont bother, but it makes a significant difference in responsiveness, smoothness, and top-end power. Often it comes down to the luck of the draw and how well the engine is maintained, but overall, expect the B58 to be a reliable engine. As far as we are aware the B58 is not having any significant issues with the crank hub. Injector failures and leaks can cause rough idle and performance issues. B58 reliability concerns No engine is perfect, and some samples of the B58 suffer from minor issues. Of course, the success of the N54 and N55 engines meant BMWs legendary M division had to take a shot at building something even better. Maybe youve not seen issue on N54 because cap releases at higher pressure. On the forums you can see logs people recorded showing DME demand and the position feedback chasing it. However, you may make it well past without issues. In normal condition like drawing to grocery and not even touching accelerator, you will never see this happening, but when doing hard acceleration because you want to get out of dodge, negotiate out of slip road and you need to rapidly gain 40mph, just having fun In 2010, the 335i received the updated N55 engine followed by the B58 in 2016, however, the model was rebranded to the 340i. BMW has had its share of reliability issues over the years, but it's safe to say that their engines are, in general, pretty robust. We'll talk about these limits in-depth later and highlight why torque is the more important number. (4.2 l)My '06 TJ has the 4.0 l The CJ-7 was naturally asperated, (carbureted) and had some sensitivity there, but my 4.0 l is fuel injected and has been rock solid! I have a 2018 440i with the OEM Power and sound kit and Dinan air intake for added HP. If possible, How much would it cost? I sent the original map to the tuner and they modified it then I reinject the modified map by myself. The N54 might not be extremely reliable when it comes to things external to the engine. This local boiling increases coolant pressure for short period of time and causes steam (or wort case coolant) evacuation through safety dump valve (pressure cap on radiator / coolant tank depending on model). Deposits can cause misfires and power loss. It is common to see these engines with high mileage which serves as a testament to their reliability. Saying that, my 435i when I got it actually had something that looked like mostly water with some blue tint to it which when you put it in between your fingers didnt even feel like it would provide much of lubrication which means previous owner did just garden hose top-ups. B58 engine reliability BMW engineers were able to resolve the main issues with the engines that preceded the B58, including: Updating the fuel system Modernizing the cylinder head They fixed issues with the particulate filters A fresh design for the timing chain So far the valves have been cleaned, DME & transmission software has been updated and most recently the 8 speed auto transmission was completely replaced by BMW Sydney but the problem persists. The B58 is a great engine, but the S55 is better. At 28k miles I had a warning light low coolant. Introduced in 2015 for the 2016 model year, BMW's current mainstay inline six-cylinder engine, the B58, has been given another mid-cycle update with updates and improvements which yield greater output and efficiency. Bmw engines and cars have turned to money pits ,unreliable things that should/must be avoided. Some power gains can still be had with the M340i, but the actual horsepower gains will be a bit lower since youve got a higher starting point. other than that it runs good and I still like it. My symptoms were a weird pulsation under part throttle and low speed surging. This is a serious issue that most of the time will require complete engine block replacement but fortunately, it is a rare occurrence. Your email address will not be published. In terms of engine and chassis design, BMW is still one of. 49 32 comments Best Add a Comment ijustbrushalot 8 mo. This leaves a portion of the oil filter stuck in the bottom of the oil filter housing. Ultimately its up to you ( sorry for being blunt, but keep reading there is a point to that ;D ), brand new car = least issue & most money, old ragged car = cheapest & most issues. Only tool I needed was a small flathead screwdriver. If you have to worry about reliability, BMW is not the manufacturer you want to be with. Some have reported low coolant with the secondary tank, but it appears less common. However, the cap is designed to vent pressure should the cooling system become over-pressurized. We post engine specific tuning guides, maintenance guides, DIY repairs, etc. So much too learn, so little time. Our garage currently includes a 2008 135i, 2007 335i, and 2008 535i. Most B58 owners will have a trouble-free ownership experience and spend less on maintenance than if you were driving a N55-powered BMW. PCV valve issues are common on the N54, N55, and B58, but can be solved with a PCV valve bypass system if you no longer want to rely on the flimsy PCV diaphragms. A 2017 340i M Sport uses the B58 engine, which is a single turbo. That got lemoned (hpfp issues). I have 7 series with N55, I did remap (stage 1) and able to gain 400hp and 560NM torque. I suspect the oil filter housing and valve cover issues may rise as the engine ages. One of our N54s went 113,000 miles before its first walnut blast. Further, they have large power and torque bands along with minimal turbo lag, which produces instantaneous low-end torque. That being said, there are a lot of bad engines out there! Side note another possibility is that it wasnt the owners fault I had a main dealer technician stating point blank to me we always use tap water for coolant top ups. Glad I wasnt imagining this weird phenomenon . To find out more, read our Privacy Policy. Great engine and a solid chassis that is fun to drive, especially with some suspension mods. Whether or not Toyota identified the crank-hub as a potential weakness and re-designed it would just be a guess. We appreciate the positive feedback! Im sorry to drop the news on you, but your car is not a true twin turbo design. Lastly, issues with waste-gate rattle were mostly resolved on the N55. It cleaned up ignition timing a little bit, too. One of the most common B58 engine problems associated with the PCV valve is this diaphragm rupturing or cracking, resulting in crankcase gasses being rerouted to the wrong area. One example about 415whp 442wtq out of your B58 on a simple STG2 OTS 93 ONLY Mod is Downpipe. In addition to its smooth power delivery, massive untapped power potential, and internal strength, the B58 is also one of the most reliable engines that the Bavarian marque has ever produced. Had n55 in a 2011 335cvt, w manual. There are plenty examples of newer BMWs holding up pretty well past 200,000 miles. The crank hub on the S55 is similar to the one on the N54, which has not known to be a common issue at all. Peak power at just around 16psi. Since the initial release of the BMW N54, the engine has gained quite a positive reputation in the tuning community. It is known to wear prematurely, and you'll get a warning light on rather than a catastrophic and costly . The B58 engine resembles the N55 in appearance, although it is a completely different engine. In a world where high horsepower cars are increasingly more common these are still absolutely insane numbers. Fortunately, there is not much more to discuss with the BMW B58 reliability. what a great site you have! Ill try to describe what I suspect as a secondary issue. Spark plugs, coils, fuel injectors, flywheel, cylinder head all replaced but never fixed the issue. Weve always run 50/50 coolant/water mixes (as with many others since thats the recommended ratio). Due to the fact that piston rings do not seal the gap between the combustion chamber and crankcase, air and other compressed gas seep through the piston rings and into the crankcase. There are countless videos of B58 BMW owners with this exact symptom resulting from a damaged PCV. Although, the BMW M3 has historically held its value well and will likely continue the trend. Completely misread that. Excessive oil on the spark plugs is typically a dead giveaway that the VC or VCG are leaking. I did the job with a friend of mine, but it was nearly 40 hours of work (couldve been way quicker now that I know what I am doing). when removing the reservoir cap, I noticed a bunch of crustiness. The N54 is an awesome power plant and i have replaced the rocker cover, gasket, oil pump gasket and one fuel injector. Scotland to be precise. Just remove all the plastic covers and you can get your hand back there. This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register. Ok, definitely my thought process as well. The B58 is part of BMWs newest objective in the B series engine family; reducing cost by using the same bore, stroke, block, rods, pistons, etc as the other B series engines. With that being said, there are some shared issues between the three engines, like VANOS solenoid failure and oil filter issues. Awesome car and congrats on the new tune. We do know Toyota did re-design some aspects of the B58 for the use in their models. If you get a downpipe and aftermarket tune youll definitely want to remove the cold start function. Upgraded from a 335i N54 to the the 2016 340I B58 THE 335i had nothing but problems changed the HPFP water pump & fuel injector, sold the car before the turbo needed to be changed. Disintegrated oil filters pop up frequently, but are not serious in most cases. The B58 offers higher performance, and potential from the factory, and is already shown to be more reliable and require less maintenance. Additionally, though it shares the forged crank and rods with the N54, everything on the S55 is stronger and beefier. Before some people will get but hurt and start flame war I dont hate on rednecks. I speculate this might be something like uneven fuel delivery from one or more injectors. Hopefully, it's not as bad as the below image. Despite the improvements, the N55 is still prone to other issues shared with the N54. Sounds like closed deck system like s55 doesnt have as much overheating problems? It has honestly amazingly smooth power delivery and sounds better. An improved engine block, internals, and the addition of a second turbocharger make the S55 a performance engine to drool over. Stupid technicians, or cheap skates that mix coolant with distilled water cause cooling system boiling point to fall. From my understanding it is a fine engine.Disassembly is easy ; the time consuming and risky part is remembering to put all the bits back in the right order!Main costs of maintenance will be consumables such as tyres and brakes. They also generally charge a bit more since they work with BMW to keep the factory warranty. Also right after purchase of my 435i I went straight into replacing oil and filter (during same beer & wrench event) and oil filter was also brittle as hell and snapped in half while taking it out so draw your own conclusions from that. I have a 2011 335 x drive manual that I love. My m140i has now been back to the dealers 3 times in the last 9 days.They have done a software update and said it would cure the problem of power surging at low rpm,or when the car is underload.
