Leaking at Charge Pipe/Diverter Valve Seal
My DVs were not making a proper seal to the charge pipe as evidenced by oil/dirt buildup at the base of one of them. The raised boost must have been blowing oil past the o-ring at the base of the DV. I have attempted to solve this by ordering a slightly larger o-ring that fits more snuggly against the DV shaft. So far it seems this will have solved the problem just from how much tighter the seal feels. I have cleaned the area and will check back in a week to see if the problem is solved.
The part number I ordered was McMaster 9262K553. 3.5mm wide with 24mm ID. The new o-ring is on the right and is only slightly thicker than the old one (but thats the point). If anyone else has leaking DV seals, PM me and I can mail you some.
