Intake manifold gasket replacement question

projectpanda · 10-17-2018, 08:14 AM

I'm getting ready to replace my upper and lower intake manifolds with ported ones and was wondering which gaskets can be reused and which have to be replaced?

It seems the throttle body and the upper-to-lower manifold gasket are the same material and can be reused. The lower manifold-to-head will have to be a new one.

Can anyone confirm for me? Thank you

As a rough rule-of-thumb, elastomer gaskets (silicone, rubber, etc) can be reused. But there a lot of variables involved.

Paper, fiber, etc gaskets are generally one-time use only.

Get new gaskets.

Why reuse old stuff. Just get all new gaskets. Intake leaks are hard to detect.

Thanks, Not going to lie, I was trying to save some money on the throttle body and upper manifold gaskets, but considering this will be right before my tune session, better to be safe than sorry. New gaskets it is.
