Intake Gaskets

I have reused felpros several times. And with no sealer whatever except the standard silicon-in-the-corners.
Have you tried retorquing?

Yes, I did check all the bolts just to be sure.. They were all still torqued to spec.

I used RTV on the intake side and copper on the head side of the gasket. I think the RTV is going to inhibit me from reusing them. So I better get another set on order just in case. Damn that is frustrating.
