Here's where I am now. Not a bad job (so far). Mine was leaking for sure and the o-ring is a little crispy

I wasn't expecting but a few drops and ended up with a face full of oil. This much oil came out of mine:

Is your pan/shield full of oil or is that water?

My pan was WAY dirtier than that. Nice and clean now though. My o-ring was completely squared off too.

[QUOTE=TigerDave;1064874511]Looks like I'm not the first to come across this:

http://m3forum.net/m3forum/showthread.php?t=202623

These M10 bolts apparently stretch upon installation. The idea is to torque them to 43 ft-lb, and then stretch them by turning the bolt another 90 degrees.

At $2.50 per bolt, I'll just go buy some (12) new ones to be on the safe side before tackling this job.

I havent took of the subframe reinforcement plate but I just by 12 of the same bolt, or are they different sizes?

Yep, it's full of oil

An amazing amount of oil seeps out of that pesky CPV when it leaks.

Got me a can of brake cleaner and prettied up my reinforcement shield after replacing the CPV o-ring. No more oil!
