Not my intention to derail the thread, but I'd be curious to know if that oil buildup issue might be due to overfilling with oil?
It's a stupid, yet common practice - one which I've gotten into shouting matches before - to blindly add an ounce of oil when doing an a/c service. Don't know where it started, don't know why. But damn near everywhere I've seen carries it forward. Guess measuring how much comes out during an evac is too difficult?
Have seen this too. Such a problem that gm added a filter. Never saw this problem when the pump was at top like the previous generation 5.7's.
