Intake plenum gaskets?
Just replaced my plenum and runner gaskets this summer, now I think I gotta pull it all apart again cause I think my lower intake seal might be pissing out oil. That smaller portion on the rear of the intake by the distrib.
So my question is do I have to replace my plenum gaskets AGAIN after just doing them?

I've reused the same plenum gaskets for 10 years and I've had that plenum off a hundred times. Unless they tear apart when you remove the plenum, you'll be fine.

I spray pam cooking spray or a light oil on the paper air only gaskets. It helps keep them reusable.
