Waste gate is in system - except when I plumbed in thru the intercooler nipple - which removed the w/gate from the system. No change. W/gate in reasonable nick - altho can detect very small bleed from there. Have stripped and refaced valve and checked diaphragm.
If I have pressure on my test gauge, I can't see how I could have a leak big enough , for the small amount of gas I am putting in, for it not to register on clock gauge?
Have hunted for leak, but can't find any - at least not significant. Have not applied any sealer to exhaust blank plate - but figure with gasket it has to better than straight overlap. Can't hear any gas or feel any at that point. There will be a small bleed at that point - perhaps like waste gate.
So, is there a particular point in engine rotation that this test can be done without exh overlap? I would suspect not, if the cams have overlap.
