BMW N54 2008 Engine block rebuild overhaul DIY

I am now in the process of rebuilding my engine block. Shooting videos to show the process (for those who might be interested).


The long story short…

Had oil leaks problem (bad, very bad).
Corrected a few:
- Recently changed oil filter housing seal (few months ago)
- Oil cooler flange seal at oil filter housing
- Valve cover seal
- Cylinder head gasket was done about 4 years ago

All those fixes helped. But others were still to be done. I remember how big of a job it was to take out engine and transmission. Somehow, I was trying to avoid going there again (as I knew it was a big job)…

Initial thoughts: I have to replace crankshaft seals (both) and oil pan gasket. Since these are great amount of work, I have decided to check engine compression. All cylinders are within a 5 psi window, between 110 - 115 psi. Engine compression test should be above 10 bars (145 psi).

So, in the end, I'd rather taking engine out, rebuild the block. I'll have it in hand to fix seals and gasket issues.



I have open a Youtube Channel “Quebec DIY” to cover the entire process.

I thank you for the amount of pain and suffering you have inevitably saved myself and others from. The future of a blown engine looks a little bighter now.

Glad it helps.

I like to think that the best is yet to come. The assembly is the best part (at least to me)...

Should begin to assemble engine block this week

I am planning to get my 2008 335xi e90 6AT n54 motor pulled out at the end of the year by a friend. I have 176k miles currently and anticipate having 200k miles on the clock by then.

Would you be able to provide a list of what parts worked well for you on your car upgrade? I want to refresh as much as I can on my car while it is apart. My car is in california. I plan to buy everything from FCPEuro for the refresh. My car has been FBO since it had 40k miles on the clock.

Thanks in advance.

Sorry for the delay guys, I've been under the hood for quite some time!

Best advice, would be to go through www.realoem.com to review the parts. I did it prior to get my parts and it helped me for some stuff I forgot.

Your list might differ than mine. Here is what I got (might miss a few things and there might be some you won't need).
