914World.com _ 914World Garage _ Throttle to Plenum seal

Posted by: PCH Dec 23 2019, 02:27 PM

When placing a new throttle body to plenum gasket, do you put some sort of sealer (like Formagasket) on the gasket?
The previous gasket had a sealer on it.

Thank you for your help.

You shouldn’t need it if the surfaces of the TB and plenum are super clean. Torque down the bolts each a little at a time.

Common spot for vac leak, there is a gasket that should be placed between there at least I have always had one on my 2.0 D-jet

A thin smear (thin!) of The Right Stuff can’t hurt.

Gasket yes. Goop isn’t needed if surfaces are properly prepped.
