trick for pinpointing hpo leak????
So I have my valve covers off and air to icp port and can command ipr closed. Pass side seams to be air tight. Drivers side is blowing air through like crazy but I cant pinpoint exactly where. By this time all the oil is pretty much out of the rail and I just have a constant hiss. It gets a little louder when I chsrge ipr.
My question is, what do you guys do to pinpoint exactly where theleak is????
I have already replaced all injector o rings. Stand pipe and d plugs as well as oil rail seals. Inspected nipples for damage. All look goid but I definately have air basically free flowing outsimewhere . Please help
