Oil Filter Housing Gasket - Replacement (M54)

Refer to the PDF and if anyone has any problem with the file, let me know and I will post it again. This DIY is for 2004 525i with M54 engine.

Very helpful! I was able to follow these steps and successfully complete the oil filter housing gasket replacement. Do you happen to have any instructions on replacing the heat exchange gasket? This is also leaking.

I'm afraid I don't, as I don't even know where is the heat exchange gasket? Are you referring to the cylinder head cover gasket?

Thanks for the DIY. Planning to tackle this along with the VANOS. Is there an RTV Sealant used along with the gasket? Or is it simply,

1 remove old gasket (scrape)
2 clean area for new gasket
3 install new gasket

No RTV sealant is needed for OFHG.

Excellent DIY. When I did mine on my previous e39, I found that in removing alternator, spraying a bit of wd40 at the contact points to the engine block makes it come out nice and easy with no jerking necessary.
