Putting the intake on my 270 Poly motor and it has metal intake gaskets. Do these require any sealer on them? They have the raised bead around the ports but I wonder if they will seal water when put on dry. Thanks for any replies.
I just installed the intake on a 318 Poly in the '62 Dart....... Good how-to article here. In the Fel-Pro intake kit was a small tube of black RTV. The instructions say to use RTV around the water ports, and use a gas proof sealer around the intake ports much like the article above. Instead I used Hylomar on all ports, tossed the foam seals and used Right Stuff on the ends. My next choice would be Aviation sealer, and if I had to choose an RTV for the water ports and ends, it would be Ultra Copper.
Prolly quadruplicate or more. Anyway, I usually slather grease on all four surfaces when installing any kind of lowtemp gaskets like this. Usually makes it a lot easier to disassemble/remove again if you have to. Jack E/NJ
