Intake manifold plugs
« on: March 09, 2016, 09:59:03 pm »
Does anyone have best way to go about what to use for sealing the brass plugs to the intake manifolds? Which is the best > teflon tape  or some type of sealant or high temp silicone.

For general sealing of 1/2" and smaller pipe threads apply two full wraps of white PTFE tape in the direction of thread tightening followed by a smear of good quality PTFE paste sealer.

It's difficult to know just how much you don't know until you know it.
In other words... if people learn by making mistakes, by now I should know just about everything!!!
