Inlet manifold gasket leaking

[cossiemanden]

Hi guys
I'm using the cometic plenum gasket for my hart racing inlet and its leaking like an open bottle
What are people using?
Can i buy the rubber that fits in the cnc'd channel on the plenum?

...have you drilled threads holes on the plenum which is bolted on head?if no it will leak as you cant tight it properly..

I did that the first time i found a leaky gasket
But my cometic gasket folds when its installed.....

Use sealant as well as a gasket

Problem solved, new plenum gasket installed
