Hello all my name is Boris and im from Germany. I have powdercoated my Air intake and did not think about the Plastic gear on the side of the Intake Manifold and now its melted. Is there any repair possible or do i need a new Intake manifold? The car is a 1994 GTO NA…
There are also plastic shaft bushings and a shaft seal that are also damaged from the heat. I had a similar issue and could not find replacement parts. The best solution is to buy a new NA plenum and swap the necessary parts to your powder coated plenum. You will need to separate the plenum sections to gain access to all of the components. Not fun.
