But anyway, you should be looking for other things to justify how good previous owner's oil changes were. Look/inspect the cam lobes , pull the cam cap and check for wear. But you need to know what you're looking for .



Anyway... about the cam cover, i've popped lots of E46 valve covers and have never seen that residue on those, including my own. You can eat off of mine.
