Spark plug problem
I've looked online and haven't quite found a similar solution. Maybe I'm not searching right.
Below is a picture of one of my spark plug that I took out. Are first I thought it was the VCG but there wasn't oil anywhere else but on the thread and electrode.
Am I right to think its not the VCG or do you guys think it is?

Best of luck.
That is pretty severe carbon buildup, probably due to oil fouling from either 1. oil escaping past the piston rings, 2. worn valve guides and/or 3. worn valve seals. Of the 3 possibilties, 3 is the most likely (at least in the N62 engine), followed by 2.

This is not a valve cover gasket issue, you need to address this issue BEFORE it blows up on you and before you drive it further. Please follow what i told you above if you would like to possibly save your engine. Compression check is most important. Go to sears and buy a compression tester. No harbor freight junk for this. Search google on how to do a compression check.
Best of luck!
