Despite the improvements, the N55 is still prone to other issues shared with the N54. Thanks! This can result in oil-rich gasses being pumped into the intake manifold. . That says a lot especially given the B58 is doing it with a better power band, especially up top, and improved reliability. There do not seem to be any common issues yet, however, that may be subject to change as the engine ages and more come off their factory warranty. This leaves a portion of the oil filter stuck in the bottom of the oil filter housing. This isn't absolutely necessary but will help get any possible filter debris out of the oil. Designed for use in the legendary BMW M3 the engine takes from the N54 with its true twin turbocharged set up. We use cookies to improve your experience on our website. We also think the B58 should hold up a bit better as it ages. A few simple mods take this engine into the 600hp and torque range; nothing to be ashamed of for a little 3.0L inline-6. 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. 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. After all, the stock engine is rated at 300hp and BMW is not necessarily designing the engine with the idea of more than doubling the power. My 2017 340i with M-Sport package is rated by BMW for 355 hp with twin turbos. Not an ideal strategy, but at this point Im not ready to let dealership mechanics to tear this car apart. Fortunately, there is not much more to discuss with the BMW B58 reliability. Guessing you are all semi-auto owners.. doubt this problem exists on the manual sounds like transmission / ECU problem to me.. #. It can trap heat for up to roughly 36 hours. Thanks. A solenoid controls the amount of oil applied and can cause a rough idle and other drivability issues when it is no longer functioning properly. **Ranks are as compared between the four turbo, inline 6 engines**. And thats the N54 which is regarded as one of the less reliable BMW engines. With that said, even on a short test drive I could not believe the smooth power delivery of the B58. Additionally, it receives the forged crank and rods as with the N54. Ill take it up with the dealership once we are all in better times. Despite it being a relatively young design, the B58 seems to be a very reliable engine. Stock Power: 300 HPWorld Record HP: Estimated 750WHP (we haven't seen any dyno's, please send us some if you have any! Your comments are welcomed. Since then, Ive been wait for Dinans Stage II, III and turbo, but, nada. in. Certain G series models began receiving the updated B58TU1 in 2019. Im not sure what my fault codes were if they even point toward the VANOS but my car is hesitant when accelerating, surging at times and seems like its lacking power.. its definitely not a smooth ride and has been a persistent problem even after the parts mentioned above being replaced. Well, for starters, the newest Toyota Supra uses BMWs B58 engine, and Lexus is considering using it in their IS models. Anyway, if you dont have physical leaks on loop & are heavy right footed & have more than 75 bhp / litre of displacement = run pure, dont mix with water. 350-400whp will require at least a decent set of performance tires. Ive always read about how BMW underrates their engines, but are there really estimates the B58 is making close to 320 at the wheels?! F11 151k miles (now only tuned by 30%, in the past was tuned onev 40%) However, it wasnt as drastic of an improvement as some say. The B58 is a marginally larger engine displacing 2,998cc compared to the N55's 2,979cc and weighs 18 lbs more, but while making notably more power. However, it's fair to chalk up minor coolant loss to being natural. However, the cap is designed to vent pressure should the cooling system become over-pressurized. BMW Reliability Most Reliable BMW Engines. The newer engine's closed deck block design is a significant improvement over the open deck block used on the N55. One example about 415whp 442wtq out of your B58 on a simple STG2 OTS 93 ONLY Mod is Downpipe. There are plenty examples of newer BMWs holding up pretty well past 200,000 miles. Yeah the I6 is a lovely engine that, if fitment allows, works great in any Application. In terms of engine and chassis design, BMW is still one of. The Grenadier will be no different. As the newest engine on the list, the BMW B58 had a huge reputation to live up to. Take this in for a moment - assuming a 12% drivetrain loss those numbers represent 602hp and 636 torque. Our garage currently includes a 2008 135i, 2007 335i, and 2008 535i. Happy I stumbled on this website and will definitely be reading more. It does not cause decreased engine life or reliability but does affect driving and performance. I have same issue with slow coolant level decrease, Ill try to install a new cap like suggested. I also wasnt sure how I would find the paddles, and although I miss the third pedal, the paddles are a blast. Stupid technicians, or cheap skates that mix coolant with distilled water cause cooling system boiling point to fall. Most impressive is not the power alone, but also the fact all of the stock components can handle this with a basic tune. Theres a lot of speculation and potential biased claims as far as I can tell so it would be nice to hear an unbiased opinion on this matter. Thank you, Zach! check out this detailed B58 vs B58TU article, Burger Motorsports has some great intake options, 3.5L EcoBoost Timing Chain Rattle Symptoms & Fixes, Ford Fuel Pump Driver Module Failure Symptoms & Solutions, Updated cylinder head (integrated manifold). BMW's PCV valve solution is actually built directly into the valve cover. Love the car but hate the pain! Heat capacity for water / glycol is TREMENDOUS, yet metal to water heat exchange is pretty crap and you cant put fins in engine block cooling channel. 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. Trust me she still has a lot of life yet to go. For more information, check ourdisclosure. The car seems to have lost some pep. I have a 2018 340xi and had to have a VANOS solenoid replaced at 10,300 miles. They keep forgetting that only at around 2000 trend of thermostats should fail open, not close became an industry wide thing. Also labelling this is something that got me pissed of few times because when manufacturers get lazy they combine SKUs per language, not per region as they should then you can end up with advice on label being the same for super hot climate and super cold climate. Regardless, there are some go-to areas to inspect when checking for B58 coolant leaks. Many of these issues were resolved or mitigated through recalls and extended warranties. Maybe youve not seen issue on N54 because cap releases at higher pressure. Our garage currently includes a 2008 135i, 2007 335i, and 2008 535i. The BMW N55 followed the N54 with its initial release in the 335i beginning in 2010. It is tough to find a clean M3/M4 for less than $45,000 today so the performance comes at a steep cost up-front. An S55 powered M3 can be found for roughly $10,000 more than a B58 car. Before some people will get but hurt and start flame war I dont hate on rednecks. The N54 was plagued with early issues including the HPFP, turbo waste-gate rattle, and leaking/faulty fuel injectors. Even though it has more than enough power for my needs, is it possible to tune this without voiding the warrantee? Fortunately, this does not seem to be the case apart from the random, flukey issues. Minor leaks may not produce enough smoke to notice. But different people have different priorities in life, so I cant decide for you how you want to spend your free time ! Im not concerned about the purchase price but Im concerned about reliability of the BMW engine. Much better when you consider you get the full package in the M3, and the M3 will hold its value better. It manages a respectable 322-382hp and 332-369 lb-ft from the factory. Yes Im in the UK John. Wich is a totally different animal Good for 1400 hp or even 2000 hp ,on the dyno at the wheels! Haha your last comment seems to be spot on! Outside of that, meth definitely has some great performance benefits. Sometimes, B58 coolant loss can be dependent on other things as well. my buddy still has: 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. Although the B58 uses similar rubber VCG's, the engine has one advantage. 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. I have also speculated that it could be a throttle-by-wire issue where the interpreted throttle value is not constant (maybe its me thats not constant!!). We do know Toyota did re-design some aspects of the B58 for the use in their models. Yeah - a straight six is a beautiful thing. It does not have signs of issues with any of its internal components. Most repairs at the dealer will easily run over $1,000. Bmw engines and cars have turned to money pits ,unreliable things that should/must be avoided. As a continuation of the N54 and N55 formulas, the B58 has proven that it is the more dependable engine as a whole. Ram/Jeep had plans to come out with a turbo powered I6 to replace the 5.7 Hemi, but nothing seems to have come from that. However, there is one catch on the B58. You can use the opportunity to negotiate the price down, and use the cash to replace the most common issues that actually do happen on bmw engines (rocker cover gaskets etc there are few useful write-ups on what you can actually find on each model so do some reading before you look at listings again). JavaScript is disabled. Proceed with the oil change as normal. Therefore, I will not purchase a BMW unless it is a certified BMW. other than that it runs good and I still like it. The talker a 6th gear I can find the better. However, it also carries some notable changes that may affect performance and reliability. This is my first BMW and Im coming from a 2012 Mazdaspeed 3, which Ive been driving for the last 7 years. Thank you. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); This is a wonderful post so clear and easy to follow. BMW's B58 and S55 engines are newer, so more issues may pop up down the road. Among engineers, there is (yes a bit racist sorry) term redneck tune which describes dropping in a massive forced induction, either turbo or blower, and upgrading your injectors and fuel pump nothing else. 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. Reliability + performance. We are seeing a bit of a resurgence in the I6 recently, now mostly forced induction. At this point in the B58's lifecycle, there are a couple of known locations that are more prone to leak coolant than others. Conclusion. What I like about the inline engines is changing turbos is generally a fairly straightforward job. Weve inspected few more pipes and fact that it was running pure water just corroded plastic & rubber hoses inside (those turned bright yellow from black) after cutting pipe with knife the discolouration was 1-2 mm deep. Currently stock on stage 1. AND BTW, I dont know whenever new caps will fix anything. I hope to get a 2015 M3 in a few years time as i would love to drive the S55! You should replace the B58 oil filter with every oil change, anyways. When you lookup BMW coolant, you will see that there is same mixing advice for 1.6 non charged 80bhp mini cooper for Canada region and M3 for UAE region. Was stock. We appreciate the positive feedback! Im not convinced there isnt a secondary issue. The rough idle is a symptom of the VANOS solenoid. Ok, definitely my thought process as well. Though, it may be excessive on lower mileage B58's. Space is very limited but its doable. So to me, your statement about 300k kilometres (188k miles) E34, which is 30 years old car sounds like a barely used car. Required fields are marked*. BMW techs dont seem to know how to resolve this. Replace valve cover gasket and oil pan gasket at 160K. Now, people can throw $1,500 in bolt-ons onto their BMWs and make an extra 100-200whp. Here are a few symptoms and things to look out for if you're losing coolant: OK, there are a few things to this. Of course, we are biased towards BMWs here at BMWtuning.co, but we fell in love with these modern turbo BMW engines for a reason. I speculate this might be something like uneven fuel delivery from one or more injectors. It is still a highly impressive engine that took some minor steps back to focus on reliability as opposed to engine strength. At 28k miles I had a warning light low coolant. (cold start is just supposed to head up the catalytic filter in the downpipe, so thats why its commonly removed after catless downpipe installation.)e. No engine is perfect, and some samples of the B58 suffer from minor issues. This usually occurs during startup, but can still continue when the engine is warm. BMWs B58 and S55 engines are newer, so more issues may pop up down the road. Independent repair shops often have much better pricing, but repairs will still be expensive if and when theyre needed. Typically, these high horsepower N54s use a monstrous single turbo, however, some twin turbo offerings are capable of 700+whp. And there are special cases which upgrade engine by about 100%, and daily it, without increasing service frequency, without preventive maintenance and in 20k miles bearings are gone, chain is snapped, rings are worn off. Its a pretty simple 20-45 minute install and uninstall. A 2017 340i M Sport uses the B58 engine, which is a single turbo. Not sure which car you refer to when you say single turbo. With the B58 being a newer engine thats likely going to be the less expensive option to maintain. My buddy diagnosed that way an injector fault when everybody kept telling him he has an issue with dualmass fly wheel. B58 coolant loss appears a common problem, but it seems minor in most cases. Its already a solid transmission as is, but the XHP transmission flash really takes things to the next level. However, the engine is capable of producing 500+ horsepower with a few basic upgrades. 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. Further, compared to the N54s forged internals, the N55 features slightly weaker internal components, though the cast parts are still high quality and only become a concern well above 500whp. Maybe FORD forums are for you? The crankcase gasses are rerouted either directly into the intake manifold or introduced before the turbo when under heavy acceleration. 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. The first indicator of an issue was a check engine light. Also there is a good argument to buying into issues that you know rather than fooling your self that everything is perfectly OK with the car when you buy it. This is a misconception. what it was please. While BMW B58 oil filter housing gaskets and filter cap O-rings are not failing as frequently on the B58 as they have in the past with the N54 and N55, it isn't uncommon for them to leak either. Of the engines referenced in this post Toyota is only using the B58. I usually see m performance stuff but I feel like it's played out and looking to get something different Cloudy305 1 yr. ago However, the initial value in purchasing the N54 may diminish due to potential reliability issues. Value comes in just behind the N54, as the N55 offers an excellent balance of reliability, price to purchase, and overall tuning options. The BMW B58 engine is a remarkable one. I add small amount of coolant from time to time, but nothing crazy. N55 water pumps are notorious for their low lifespan. should i stay away? However, a couple quick notes that are imperative to keep in mind: Regardless, the B58 is working up to be a reliable engine in its young career. Coolant loss The B58 uses two coolant tanks in its system. 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. Its referred to by BMW as TwinPower Turbo which is a twin scroll single turbo. Awesome car and congrats on the new tune. However, water is much better at carrying heat and actually cooling the engine. My history with bmw is: Dinan offers stuff thats covered under warranty. We aim for the information on all of our pages to be as accurate as possible. You can say we are somewhat N54 fanatics. It cost about 180 Euro. Although, VANOS work can be done without lifting the engine. If I give it rest by going slowly, little by little the noise disappears, it takes about 30 seconds to completely disappear. Hi Hank, Ive currently been having issues with my M140i. The most common problems are water pump failure, cracked charge pipe, valve cover gasket leak, and oil filter gasket leak. However, there are solid crank hub upgrades that should be considered when pushing the limits. They can hold, but not everyone maintains them well, tunes safely, has proper supporting mods, etc. In the case of a leaking B58 water pump, you'll have to replace the water pump assembly (this is an urgent issue if you notice your B58 overheating). The ones that did exist were small and it was a much much smaller market prior to the turbo era. Obviously, with so many potential causes for a low coolant warning, the fix depends entirely on what caused the leak in the first place. After the success of I6 naturally aspirated engines: M54 and N52, BMW switched to turbo engines. The B58 uses two solenoids. Im not sure how many as I was never given any job sheets. We did not include that as we do not consider carbon build-up an issue. In fact, it may not have an equal among all engines on the. Just go hard more. Turns out coolant was getting into the engine.

One of our N54s went 113,000 miles before its first walnut blast. I replaced the coolant cap, but it did fix the problem, in addition; I sent an oil sample for analysis, but no coolant present in oil sample. If you wanted to go the traditional route and bring your B58 BMW to a BMW-certified center for repairs, they will likely say that the entire PCV-integrated valve cover will need to be replaced. 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. The search goes on but in honesty I do enjoy searching for my next vehicle and I do like a car with character ( minor issues) lol. So, we've got a bit of a headache here. Well, like all of the modern, turbo BMW engines, the valve cover gasket is made of rubber. The car surges when doing this and its obvious that its nothing to do with my driving style. Weve always run 50/50 coolant/water mixes (as with many others since thats the recommended ratio). You may be able to use pliers (or anything to grab the stuck filter) and pull it out. 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. Why not? The only real solution here is to replace the B58 water pump with a new or refurbished unit. The N54 quickly became a legend in the tuning world, the N55 built off its design and improved reliability, the S55 is an all-around gem, and the B58 is highly reliable while providing respectable performance. Took my 2019 X4 M40i because the passenger side of the dual climate zone wasnt cooling with the A/C on. 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. Deposits can cause misfires and power loss. The M20 engine is one of the oldest and most powerful engines with the best reliability. Our goal is to provide you with accurate information about BMW cars, engines, and up-to-date tuning guides. Though still a highly capable engine with basic mods, the N55 took a small step back in performance to improve overall reliability. Yes, B58 is reliable. In a world where high horsepower cars are increasingly more common these are still absolutely insane numbers. Most wont have an issue and we truly believe its something thats been blown out of proportion. Disintegrated oil filters pop up frequently, but are not serious in most cases. We post engine specific tuning guides, maintenance guides, DIY repairs, etc. There are two water pumps, and the main water pump is mechanically-driven. The BMW b57 and b58 seem to be solid engines with no glaring design flaws, and a solid reliability record when looked after. 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. Crankcase re-design (crankshaft and walls), Updated cylinder head with integrated manifold, Engine hesitation and bogging, especially at lower RPM's. I know nothing about BMWs and love the articles. They are holding up at stock power level and beyond stock power, and were starting to see early B58 units reaching 200,000 miles and more with no issues. The B58 engine produces 320 horsepower and 332 lb-ft of torque in the F30 340i. Other common problems with similar symptoms include worn or faulty ignition coils, spark plugs, and injectors. Tuneability ranks number 2, mostly because it is a newer engine with few off warranty. Nonetheless, you must pay to play and the N54 is no exception. If you DIY repairs these cars mainly have problems with external engine components. Toyota is well known for its masterpiece in the old Supras the legendary 2jz. [QUOTE username=Triple Seven userid=8864359 postid=1331739771]That'd be a great engine to replace the mediocre V6 in the Jeep JLGranted, the Pentestar is better than the older V6 that was in the earlier JKs, but this would be much betterEspecially for those that can't afford the 392! The BMW B58 engine can handle around 600-650whp and 550-600wtq on the stock block and internals. Scotland to be precise. e91 189k miles Lastly, issues with waste-gate rattle were mostly resolved on the N55. *Picture is from an N54 that had a leaking VCG for nearly 20,000 miles. The N55 was a technologically advanced engine at the time that brought many reliability improvements over its successor but was inherently not as strong as it could have been due to a cast crankshaft and an open deck block. Of course, this may vary a lot from shop to shop. Now I still experience a bit of coolant loss, but much, much less. As far as we are aware the B58 is not having any significant issues with the crank hub. Fortunately, BMW learned its lesson on the N54 and focused on improving the reliability of its future turbo engines. perhaps look for a used Audi 4 wheel drive convertible. Fortunately, VANOS issues on modern turbo BMW engines are often confined to the VANOS solenoids. Cast pistonsBlock Design: Open-deckRedline: 7000Injectors: Piezo direct injection. 2015 335i 4 series coupe has been a great auto. Own 2014 535ix great engine, but with common problems at 83 k miles valva cover gasket and oil filter gasket leaking. Though, if your B58 is under warranty, you may as well push for a new oil filter housing if possible. Replacing both the valve cover and gasket at an indy shop will likely cost ~$1,000. The B58 has proven to be the most reliable modern BMW engine, perhaps as reliable as the naturally-aspirated N52. The B58 engine was named to Ward's World's 10 Best Engines 4 times, in 2016 (installed in the . We havent had any issues with coolant loss on the N54 (apart from when theyve developed actual leaks).

Considered my car is stage 1 tuned. Ill try to describe what I suspect as a secondary issue. If possible, How much would it cost? Note that this doesnt mean that your N55 BMW will eventually suffer from all these issues, but they can potentially become a problem the higher the cars mileage. 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 ). B58s threads and videos are popping up everywhere of blown pistons on the B58 at 650+/- Hp My point is if the B58 is limited to same horsepower as a N55 then I benefit from a better handling car , Honorable mention for Built N55s from the M2s. You must log in or register to reply here. Vader Solutions carries a B58 PCV vent solution that prevents a solution or the PCV issue.

[/QUOTE]. Enjoy your new B58! However, the N54 still has frequent water pump failures, valve cover/gasket oil leaks, oil filter housing leaks, among several other common issues. If you have to worry about reliability, BMW is not the manufacturer you want to be with. The following table compares the technical data for both engines. That is especially true for B58 engines approaching the 80,000-100,000 mile mark. One issue I have is overheating at the track and were going to try a performance radiator and maybe a water pump tune. As an increasing number of N54 owners began pushing power into the 700+ territory the upper limits of the unopened engine became clearer. TwinPower Turbo which is a twin scroll single turbo. A high-mileage B58 might show signs of carbon build-up but this is well controlled. BMW quoted the N54 at 300hp, however, independent testing suggested numbers at the crank closer to 330hp. https://www.bmwblog.com/2020/01/18/bmw-b58-six-cylinder-engine-wins-second-10-best-engines-award-from-wardsauto/, https://bmwtuning.co/the-4-most-common-bmw-b58-engine-problems/, https://www.youtube.com/watch?v=lbc4Hs-G9Rc, https://www.autoblog.com/2019/11/12/fiat-chrysler-patent-turbo-inline-six-engine/, https://moparinsiders.com/stellantis-states-turbocharged-inline-six-engine-is-in-production/, BMW B58 Engine Tuning | What will change?
