Should I use gasket sealer? | | | | | Joined: Sep 2020 Posts: 40 'Bolter | | 'Bolter Joined: Sep 2020 Posts: 40 | Clean and dry before install is all you need. | | | | | Joined: Feb 2000 Posts: 5,205 'Bolter | | 'Bolter Joined: Feb 2000 Posts: 5,205 | I use a little high heat sealer on exhaust ports and very small amount on the intake ports. The smoother the surfaces are, the less you need. | | | | | Joined: Aug 2001 Posts: 1,299 'Bolter | | 'Bolter Joined: Aug 2001 Posts: 1,299 | I am a believer in a skim coat on both sides of gasket when installing headers of a high heat silicone sealer. Exhaust gaskets will exploit the smallest leaking area and make it bigger over time. Seal the gasket fibers and it will prevent the later leaks. | | |
