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. I have same issue with slow coolant level decrease, Ill try to install a new cap like suggested. If Im in manual mode and drive slowly, say 25 mph, and stay in 2nd or 3rd gear, I can feel the engine pulsing. 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?. Has anyone managed to get this problem sorted out yet?And if so could you let me know 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.

Trust me she still has a lot of life yet to go. 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. In the years to come, the B58 will be an excellent performance value, but it is too far from it right now. My history with bmw is: Tuned car = more power = more temperature in combustion chamber = more temperature on cylinder walls touching the coolant = more possibility of localised boiling. 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. 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 ? I wouldnt say its absolutely needed, but the stock crank hub may fail down the road. After replacing it he enjoys the car again and issue is rectified. Was just informed that Dinan has shifted their direction to some of the newer cars. Compared to the two former engines the N55 has been on the road longer, allowing for additional time for tuning developments. when removing the reservoir cap, I noticed a bunch of crustiness. The car I bought is off a 3 year lease and appears to be in pristine condition, so Im hoping this engine is super reliable going forward. .

Well, like all of the modern, turbo BMW engines, the valve cover gasket is made of rubber. Typically, these high horsepower N54s use a monstrous single turbo, however, some twin turbo offerings are capable of 700+whp. Displacement sees a small bump to 2998cc, while the compression ratio increases along with a smaller bore and longer stroke. Since the initial release of the BMW N54, the engine has gained quite a positive reputation in the tuning community. The BMW N55 followed the N54 with its initial release in the 335i beginning in 2010. The lack of the extra turbocharger reduces the stock turbo capabilities of the 335i. It's a pretty labor-intensive job. 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. Proceed with the oil change as normal. So much too learn, so little time.

Three times this has happened and Ive only just reached 14500 miles. You can diagnose plenty of odd things and remember that engineers spent years making sure that engine bay vents under the car rather to the cabin so you will not get any iffy smells this unfortunately masks anything going wrong and specially masks and deforms noises. Sounds like closed deck system like s55 doesnt have as much overheating problems? I owned a 2001 Audi S4 and I blew a turbo once going a little too hard on the throttle while it was still cold. 2015 335i 4 series coupe has been a great auto.

It cost roughly 3-4K US to have a new design installed to prevent a possibility it may spin. Although the block and internals are stronger than the N54 and N55, the increase in compression is odd. Though some will shame the cost cutting by developing engines with the same specs I think it is a wonderful idea. 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. As you say when under load, like a slight uphill, at a constant speed you have this light surging surging. Replacing B58 VANOS components does NOT require lifting the engine.

Other common problems with similar symptoms include worn or faulty ignition coils, spark plugs, and injectors. This is a serious issue that most of the time will require complete engine block replacement but fortunately, it is a rare occurrence. Congrats on the purchase! 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 ).
