Intake manifold oil leak

The Eeelbrock Performer he has there is a intake with a heat cross over. Tht intake lacks a EGR valve. The half moon shape area in the head is a heat cavity. No oil comes from it a d it's exposure is fine.

Your likely to have oil drip from the valve cover or seep up through the intake manifolds bolts. Try Teflon tape around the threads to seal the leak. No need to remove the Intake if the gaskets are working.

Some times a grinding of the valve cover is needed. I do not know if such is the case with that intake. I jus git a Performer, I need to check when I get home.
