Why the BMW N54 Engine Was a Failure

- Here's a look inside the BMW N54 engine and how it works!
The N54 engine was BMW's first foray back into modern turbocharging for the 2000's era. It's an inline 6, 3.0L twin turbocharged engine with dual variable valve timing. It did not have the variable valve lift system that the N52 has.
The engine in this video was from an E90 with 160,000km on it. It suffered from ringland failure, likely do to an overboost situation. This caused no compression in cylinder 6, and coolant to enter the combustion chamber, effectively steam cleaning it.
Other common issues with these engines are oil leaks from the valve cover, oil pan, amongst others. The direct injection system was known to leak, so much so that BMW issued a TSB to repair it. The lack of port injection meant carbon buildup was severe and periodically needed walnut blasting by removing the intake. The turbochargers were equally unreliable, with leaks, wastegate issues and seals blowing out. While expensive, turbochargers were in a tight spot in the engine bay, meaning the labor costs in replacement was also very high.
Overall the general engine layout is quite simple, with the exception of the timing cover, or lack there of. The timing guides with the chain has to be slid out the top and bottom of the block and head, which makes timing work tricky.

Anyone who thinks the N54 was a failure doesn’t know how to perform basic regular maintenance. Mine’s on 172k miles running 450hp and it’s rock solid.
I've been waiting too long for this video. I'm N54 shopping right now. I think I need therapy.
They might have been a failure for BMW's bottom line, with all the recalls for wastegate rattle, HPFP, injectors, but once you got that all sorted (which most did under warranty) to the revisions that worked, it was a great motor. Quite reliable, and surprisingly serviceable as long as you didn't need to touch the turbo side. Valve covers and oil filter housing gaskets weren't too bad, at least for a BMW :)
Wow you’re opinionated
Change the title to : "why I'm a failure of a n54 owner" 😘
Failure? 😂
I have N54 with 300.000km its running smooth without any problems. Really happy with this beast
Looks like a lot of folks in the comments got their butts handed to them by N54s. The only reason for N54 hate because it’s a phenomenal engine and has been recognized as such by everyone that matters.
These were no failure far from it.
It’s hard to believe how much plastic BMW put in their cars
Am fixing an N52 (manufactured 08/2005), and I'm just finding blown gasket after blown gasket after blown hose. It's crazy how much oil and coolant the thing is just leaking. Also they ran the injection valve / spark plug harness connection behind the engine secured by a metal bracket with 2 screws which were genuinely impossible to get to. It was fun getting them out.
I always wanted to know how those oil pumps worked, thank you very much! Great video.
It finally struck me why you point at everything with a toothbrush - so you can clear the crud off of what youre pointing at at the same time - brilliant!
Great tear down vid thanks for sharing
You didn`t remove the crank snout. That is how you remove the chain from the crank. It is not necessary to take the engine completely apart just to replace the chain. And the chain usually lasts for a long time in these engines, unlike some other infamous BMW engines.
sweet!!!! thank you for posting this!!

Great video bro, love the N54
Great video as always. Hope you do a volvo hybrid rear end and other volvo issues some day.
Look forward to seeing a tear down of B58 in another 10 years!!
