Oil appearing on Intake Below Plenum
Hey Guys,
Has anyone seen this? My car just started collecting small amounts of oil on the intake below the plenum. Thought it was the valve covers, but the oil would have to build up past the pits there the heads and intake meet. I have looked around and have not seen anything obvious. Did I overlook something?
Thanks,
BILL

Usually its coming up the intake bolt threads.
You need to pull the bolts and use a thread sealant like Loktite PST liquid sealant on the threads.
I know its a pisser on TPI intakes..but hey...you wanted to install larger runners and port the base anyway, right?
