Valve Cover Replacement

At just under 85K -- Oil leaking from VC -- went ahead and replaced with OEM Mahle VC.

I believe that the photos show that the old cover was full of hardened & crusty oil carbon type stuff. Although the old cover was not warped or cracked that I could tell - the small passage ways for the PCV oil separator would be difficult to properly clean ~ glad I change the Cover and not just the gasket.

On my old N54 engine I had just changed out the gasket.

The gasket on this R&R was brittle and would snap crack at the lower locations of the cover close to the exhaust manifold (heat cycle issue for sure).

Note: OCI have been at 5K miles with PP Euro 5W-40

Rear most (3) Cover bolts were difficult to access but using my 1/4 flex extension it was doable and was even able to torque all 3. I did oil prime by leaving the injectors unplugged but it is not necessary. Followed up with clearing codes with my Autel OBD Scanner.
