Distributor Oil Pump Drive Plug

[GTP091]

I've had my fix on my car for 6 years now and no leaks. I pulled the plenum undid the clamp. lifted the plug up until it hit the rear head lip and then cleaned the hell out of it with brake cleaner. Then I slipped a brown oil proof o ring around it (measure it with calipers) . Put oil proof RTV sealant around the oring and turned it as i let it fall back in place and kept turning it until the rtv was evenly spaced around the mating surface. Let it set for half an hour and then tightned it down slowly with the clamp. zero issues...

I have seen many times too where a owner thinks that this oil plug is leaking, and instead it is the oil distribution cover on the top of the engine where the anti-flow back valve is that holds oil in the vains between it and the cam carriers.

Look for oil where the vacuum line (to the PCV) goes onto the distribution cover on the passangers side of the top of the block, under the lower intake.

check that rubber PCV line too!! mine was DESTROYED! cracked and full of holes. this could not have been good for the vacuum or the oil flow.

the gasket set cost me like $50 for the stuff under the LIM, for both intakes... and the EGR. it even had a little rubber o ring for the coolant passage too! goo crappy tire.

Most 3.4 DOHC's I've seen that still have not touched that PCV hose have one in very bad shape, very loose or even oil soaked and swollen.

I used high pressure hose, with double high pressure clamps, and to this day, It's remained dry in the area below the lower intake.....
