When using any sealant, be sure it is designed for the application, and use it sparingly. Too much sealant is likely to cause about the same trouble as none at all. For many applications we prefer the "Indian Head" sh*llac sealer. As said, silicone sealer is not a good choice for older engines. It is used in many modern motors in place of gaskets, but they are designed for it.

I never used sealant on the intake, the gasket will compress enough to do its job, just check the intake with a straight edge, and if it is warped, the water pumps you could use #1 permatex, the exhaust gaskets should be ok,without any sealant. what I have been using is the copper spray sealant,on head gaskets, you could use this on the intake,just a light layer. hope this helps,37RAGTOPMAN STAY AWAY from the silicone sealers,they clog up oil pumps, and passage ways, try not using for oil pans gaskets,use #2 permatex,

I'm replacing a few gaskets on my 59ab and would like to know what gaskets need sealant. •I'm replacing the intake manifold gasket. I'm pretty sure to add a sealant to the intake gasket and have some Permatex #1 gasket sealant to use for that. Is that okay? •Need to replace an exhaust gasket between the exhaust header and tailpipe. Sealant needed here? •Do waterpump gaskets require a sealant? -Thanks
