The S54 has many more serious defects. I'll take this one any day. Vanos issues are the worst, resulting in whole engine rebuilds. The crank seal has been known to go on all BMWs. Also the crank harmonic dampener has been known to split in half, so I'll replace that whilst I'm there.
Crank seal cost? The seal is about $15 with a few hundred in labour. It took a good portion of the morning just to figure out from where it was leaking. The engine bay was covered in oil. Until it could be all clean off, started up and run for a while ....
I hope she lasts a while before she goes kaput. I've already picked out my crate engine LS3 kit/tranny combo, so it's just a question of when ...
