my '96 powerstroke is leaking oil again replaced the o-rings and that fixed the issue before NOW there is a little valve that comes up in the pedistal to meet the bottom of the turbo. it is on the left hand side of the truck on the back side of the exhaust back pressure valve (side where the snap ring is) but it goes vertical anyone know what this is called? and why would it have oil pushing past it? thanks
