Well, of course my issue now is, my pcv valve is easy to get at, but the plastic elbow attached to it will not come off. Of course you google pcv elbow for 2005 LS6 and nothing comes up. Seems they try to make it hard for the DIYers to save some cash and try to get you frustrated enough to go to a dealer. Any ideas? Was thinking of trying to find abouther elbow that will fit my pcv valve. Does anyone have any idea of which elbow will fit the PCV1001 from autozone, I believe it's made by Champion. Will the autograde universal rubber vacuum elbows work?
