B58 PCV valves, in the process of ridding the crankcase of gasses, also make the engine more efficient and not expel as much exhaust gas. Trust me she still has a lot of life yet to go. It has honestly amazingly smooth power delivery and sounds better. Someone knows what is due? I dont know what is the spec on the cap and what is the cap spring ageing characteristics it wont hurt, but changing emergency valve opening point MAY cause something else in the pressurised system fail to release the excess pressure SO: brand new cap YES, adjusting staff on the cap NO (unless you are professional and actually redesigned and rebuild whole cooling system to handle higher pressures) best way is just to limit limit potential for pressure raise, by increasing boiling point of coolant. BMW used an electric water pump on the N55. 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? my buddy still has: These issues seem a recurrent theme, so made me wonder about the long-term costs of maintaining the engine. 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. Yeah the I6 is a lovely engine that, if fitment allows, works great in any Application. In reality these are a tiny % of the number of engines out there.And usually someone has abused it or skipped a service.I expect the engine to be very reliable and well suited to the vehicle.At least as good as any Defender engine! A few recalls and service bulletins do exist for the B58. On the forums you can see logs people recorded showing DME demand and the position feedback chasing it. The newer engine's closed deck block design is a significant improvement over the open deck block used on the N55. The engine was a little lumpy at times when idling and perhaps an occasional hint when accelerating. We may receive a commission for purchases made through these links. Hello, I own F20 120i 2018 with B48 engine (184hp). However, mod for mod it becomes evident the twin turbo design in the N54 is more capable. 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. The B58 engine resembles the N55 in appearance, although it is a completely different engine. Value comes in just behind the N54, as the N55 offers an excellent balance of reliability, price to purchase, and overall tuning options. Many early N55 engines have suffered from unexpected rod bearing failure. VANOS solenoids may be considered a normal wear and tear item. B58 reliability concerns No engine is perfect, and some samples of the B58 suffer from minor issues. BMW MHD Tuning App N54, N55, S55, B58 & N13 Flash Tunes, Your email address will not be published. The Grenadier will be no different. The cost $60-$65 each and get a few spare clips. Its a lot of extra heat and stress on these engines. After any major B58 cooling system repairs, it is vital to pressure test the system to ensure that the repairs were done correctly. 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. Thank you for the comment. Has it happened to someone else? Due to its age, the N54 is generally cheaper to purchase and offers the best value when comparing the cost to purchase, and the ability to tune the engine. 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. Lastly, issues with waste-gate rattle were mostly resolved on the N55. B58 is obviously a winner. Could you give me some advice about this problem? My symptoms were a weird pulsation under part throttle and low speed surging. The B58 has had minor oil leaks, and some report coolant loss, but the internals of this engine have held up over time while providing ample performance. Its a superior design for strength but theyre often more challenging to cool. Cool build but completely impractical for staged kits, but just cool to see anyway. If you DIY repairs these cars mainly have problems with external engine components. Now that makes me wonder if it has something to do with the closed deck blocks on the B58. Relatively speaking, yes. It is a turbocharged straight-six engine. 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. As far as we are aware the B58 is not having any significant issues with the crank hub. Yes, B58 is reliable. Its that sad with bmw. Don't sweat it if you're only topping up small amounts on occasion. Reliability + performance. 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. 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. The VC is prone to cracking and leaking, too. So much too learn, so little time. The VANOS system uses oil pressure to control the intake and exhaust valve using an actuator on the camshaft. Space is very limited but its doable. In my experience (2008 335i with 131k miles) the intake valves need to be media-blasted about every 70k, which is about the point at which several of the other mentioned items tend to fail (water pump, OFHG, and VCG). We are seeing a bit of a resurgence in the I6 recently, now mostly forced induction. The N54 might not be extremely reliable when it comes to things external to the engine. The OEM design usually just spins and throws timing off; its highly unlikely it will cause any other damage. Love the car but hate the pain! Open-deck blocks and cast pistons are not great at handling extreme boost pressures for long periods of time. Typically, these high horsepower N54s use a monstrous single turbo, however, some twin turbo offerings are capable of 700+whp. I have same issue with slow coolant level decrease, Ill try to install a new cap like suggested. Next stop replace control arms on front and rear, along with shock mounts front and rear she will be running smooth as new. Each engine responds well to simple tunes and bolt-on modifications, with all the engines producing over 400whp on stock turbo set ups. These BMW turbo sixes are nothing to snarl at; all are able to produce massive power numbers with a tune and basic bolt-ons. Im experiencing the same as you when the car is under load. The B58 uses two solenoids. DIY the basics (oil, brakes, spark plugs, etc) $500 to $1,200 a year If you can pull out the broken filter, inspect and clean any debris. It cost about 180 Euro. The B58 has more horsepower and torque then the N55. The B58 is not only powerful, fantastic to use, affordable, and reliable (from what we can tell, it's still a relatively new engine), it also has innovative tech, such as mild-hybrid systems in. Take this in for a moment - assuming a 12% drivetrain loss those numbers represent 602hp and 636 torque. Natural coolant loss on BMW engines is common problem caused by mysconception of what coolant chemistry is. Acnam Infotech, BMW Tuning - BMW Performance & Tuning Guides, News, Videos. Your email address will not be published. This is where the B58's heat encapsulation system may come into play. Whats your thoughts on this? VANOS is BMW's terminology for VVT, or variable valve timing. Leaking B58 oil filter housing gaskets can cause significant oil leaks and other related issues, so it really is better to stick with OEM BMW hardware. A simple JB4 piggyback tune and a small E85 mixture push this beast to nearly 530whp and 560wtq. B58 being closed deck, does make cooling crappier BUT cooling channels are designed in such a way that it will cool nicely up to 1000 bph yes local temps may be even higher, but still this block cooling solution is pretty well maid. It is usually just one of the sensors but I would do both anyway. Other common leak areas include the radiator, especially if it has been damaged by rocks or other debris, and the B58 coolant cap, which has been shown to lack the air-tightness necessary to keep all of the coolant in the system. 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 ). 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. 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. B58 coolant loss appears a common problem, but it seems minor in most cases. There are countless videos of B58 BMW owners with this exact symptom resulting from a damaged PCV. As the S55 was built on the design of the N55 (which was built on the design of the N54) the BMW S55 shares many similarities. 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. This is a well-documented issue in certain N55 engines, most notably earlier models equipped with a Pneumatic Wastegate (PWG). However, fault codes will help point you in the right direction. Im impressed to say the least. Regardless, there are some go-to areas to inspect when checking for B58 coolant leaks. Im guessing something might be coming up in future Im not sure if any other b58 owners have this or if its common Leave a comment and let us know. To find out more, read our Privacy Policy. Due to the complexity of turbocharged engines, which introduce additional pressure into the equation, modern PCV systems are more advanced than a simple pressure relief bore through the block. ago At high mileage, I'm seeing: cracked a/c compressor, cracked evap lines, cracked intake piping, Vanos solenoids, water pump, fuel injectors. Sometimes, B58 coolant loss can be dependent on other things as well. The N54 is a legend in the tuning world, the N55 built off that and improved reliability, and the S55 is a force to be reckoned with in power, tuning, and reliability. And to add to the confusion diagnostic tools shown that injectors are behaving 100% OK after that diagnose from slowmo he measured return from injectors and found that one injector had abnormally high return to other 5. (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! 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. Ive had issues with my 2018 440i not idling correctly. Thanks for your help! The B58 timing chain was moved to the rear of the engine. 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. Just bought a 2017 340i and I really love the B58 so far. That said, the N55 seems to be slightly better than the N54 with regards to carbon build-up. perhaps look for a used Audi 4 wheel drive convertible. Im looking for my first sports car and BMWs seem very nice. BMW B58 vs. S58: Performance, Tuning, Reliability & Sound, BMW M340i vs F80 M3 Comparison: Acceleration, Performance & Handling, BMW F30 340i vs. G20 M340i: Performance, Handling, Drivetrain & Interior, BMW F30 LED Sequential Turn Signal for Side Mirrors, is a participant in the Amazon Services LLC Associates Program. Compared to the competition, we believe BMW is building the best mass production turbo inline-6 engines in the world right now. Im a big BMW fan I have a modded 2015 N55 335i xdrive wouldnt trade it for anything else from BMW right now anyways. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Absolutely excellent comparison, Zach. Thanks! Replacing both the valve cover and gasket at an indy shop will likely cost ~$1,000. Now, we left out some potentially promising information. Currently stock on stage 1. 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. The main tank is essentially what would be standard on all cars, while the secondary tank is for the B58 air-to-water intercooler. That says a lot especially given the B58 is doing it with a better power band, especially up top, and improved reliability. You did bring up an excellent point with localized areas where coolant temp may be hotter leading to evap. The cap leaking does seem to be a part of the cause. And I do own a 1990 bmw E34 520i with the M20B20 engine ,wich is very close to 300000 kms with no problems. Still a sound improvement for the B58. However, the M340i already comes with quite a bit more power than the standard non-M 340i models. But sometimes, my engine just doesnt want to start. I imagine a lot of (even most?) Check out babayagaracing on yt for that b58 action milkthelanky 1 yr. ago Do you know of any good sites to get aftermarket body parts? That being said, there are a lot of bad engines out there! It cleaned up ignition timing a little bit, too. If it fails, an upgraded crank hub is definitely the way to go. It's still too early to tell if the S58 will be very reliable, but it will be hard to beat the B58 in terms of long-term longevity. N55 water pumps are notorious for their low lifespan. Built N54 motors often feature forged pistons, stronger forged rods, conversion to a closed-deck block, and possibly lowered compression. other than that it runs good and I still like it. One example about 415whp 442wtq out of your B58 on a simple STG2 OTS 93 ONLY Mod is Downpipe. Copyright 2021 - 2023 BMW Tuning LLC. 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. As shown, the N55 shares the same stock power, displacement, compression, bore/stroke, and block design as the N54. Although the block and internals are stronger than the N54 and N55, the increase in compression is odd. Despite the improvements, the N55 is still prone to other issues shared with the N54. Compared to the two former engines the N55 has been on the road longer, allowing for additional time for tuning developments. ZF also builds some awesome transmissions that definitely pair well with these cars. You must log in or register to reply here. And for those with lots of money to spend theres the Ford BARRA 4.0 straight six engine! Enjoy your new B58! Now I still experience a bit of coolant loss, but much, much less. Completely misread that. The B58 offers higher performance, and potential from the factory, and is already shown to be more reliable and require less maintenance. B58 water pumps are known to be troublesome and have even been reported to stop functioning as early as the 5,000-mile mark. Original BMW coolant (the one in 1.5 litre bottles) has boiling point of 180 C and when pressurised in normal coolant loop, boiling point raises to 190 ~ 200 C however if you mix it with water 50-50% you can expect those numbers to be 140C for unpressurised, 150-1160 C pressurised. Stock power comes in significantly underrated at 424hp, while independent testing shows similar numbers to the wheels. A 2017 340i M Sport uses the B58 engine, which is a single turbo. Solenoids are relatively inexpensive and easy to replace. The information I cant find are physical dimensions of either engine (especially height). Although the B58 uses similar rubber VCG's, the engine has one advantage. Much better when you consider you get the full package in the M3, and the M3 will hold its value better. Thanks for the clarification and reply. Once the pass side is in and connected, install driver side and connect. Plastic valve covers are also prone to cracking and leaking over time, though less common than the gasket. As mentioned, this shouldn't be a huge deal in most cases. Yeah I agree with Tazzieman completely. For a better experience, please enable JavaScript in your browser before proceeding. We've seen some VANOS problems with the B58 engine. (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. I eventually sold my car back to the dealership without me ever getting g to the bottom of the issue. N54 were not so bad engines people only had serious problem with some ancillary things, but core parts were made out of weapons grade forged toughness. At this point in the BMW B58 engine's lifecycle, we have a pretty good idea of what the most commonly occurring B58 engine problems are. The talker a 6th gear I can find the better. The B58 is a great engine, but the S55 is better. Injectors are getting loud again at 200k so its time to replace them. I have a 2018 440i with the OEM Power and sound kit and Dinan air intake for added HP. Once removed there is no way for BMW to tell the car was ever tuned. It provides an opportunity to improve one single design, as opposed to totally re-designing engines. Disintegrated oil filters pop up frequently, but are not serious in most cases. Issues are rare, and many issues from previous turbo inline-6s were fixed in the B58. You can say we are somewhat N54 fanatics. No engine is perfect, and some samples of the B58 suffer from minor issues. 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. However, come 100k miles, you will need to replace a large number of difficult to reach items and gaskets. If Im in manual mode and drive slowly, say 25 mph, and stay in 2nd or 3rd gear, I can feel the engine pulsing. Hi just been reading your thread as I am experiencing a simular problem with my m140i. I too have had the coolant loss issue. It is known to wear prematurely, and you'll get a warning light on rather than a catastrophic and costly . 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. Why not? We did not include that as we do not consider carbon build-up an issue. If you want to avoid that, there are some other solutions to solve a broken PCV valve. 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. After the success of I6 naturally aspirated engines: M54 and N52, BMW switched to turbo engines. B58 is reliable, bulletproof and can handle hella boost on stock block. It manages a respectable 322-382hp and 332-369 lb-ft from the factory. Has anyone managed to get this problem sorted out yet?And if so could you let me know Injectors were changed from the piezo style to solenoid style as the piezo had too many issues on the N54, were too expensive, and did not live up to expectations. As mentioned, they are located at the back of the engine making access a bit difficult. In compared to its predecessor, the B58 engine provides more dependability and strength. Expect B58 solenoid issues to arise around the 80,000-100,000 mile mark. I do love a straight 6. Most B58 owners will have a trouble-free ownership experience and spend less on maintenance than if you were driving a N55-powered BMW. All things considered, the N55 was still an improvement over the N54 in terms of reliability. . Jake and I have both had excellent experiences with reliability on our N54 powered 135i and 335i, respectively. Although, VANOS work can be done without lifting the engine. e92 168k miles (tune about 30% up) BMW's PCV valve solution is actually built directly into the valve cover. Minor leaks may not produce enough smoke to notice. 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. Had the well known gasket issues. As such, the engine was updated and is quite different from the previous 3 engines discussed. e46 380k miles Its combination of attributes has no equal among six-cylinder engines on the market. Improvement of Valvetronic - VVT4 with reduced height. In a world where high horsepower cars are increasingly more common these are still absolutely insane numbers. Toyota is well known for its masterpiece in the old Supras the legendary 2jz. Im not sure how many as I was never given any job sheets. Your email address will not be published. Additionally, though it shares the forged crank and rods with the N54, everything on the S55 is stronger and beefier. This increases performance by. 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. , although it is a lovely engine that, there are some other solutions to solve a broken valve.
