what's the best way to seal up water pumps, thermostats housings and such? is it still necessary to use those paper gaskets plus silicone or just silicone? is there some type of gasket-maker that is better?

I like to use the paper gaskets with copper rtv on both sides of the paper.Quote:

i find that if i use red gasket sealent and 2 paper gaskets on my 350 thermostat that it will not leak.
have always used paper gasket with Indian Head cement
me, clean surface good, paper gasket w/ no sealer. leak free every time
:D Thats close to aviation gaskett shelac...:LOL:Quote:

Don
yes i use RTV on the china walls on the intake to or were poor fit up is encountered .if the gaskets has O rings on it i like to put some slip on it like on the intake i will use some white grease or permatex non drying
On my Ford thermostat housing gaskets, I just use plain ordinary good contact cement to hold the gasket on which in turn holds the thermostat in place, in the housing (remember that pot metal housing that you broke at 9:05 on a Friday night? And your girlfriend was waiting for you to pick her up at 10:00 after work at the grocery store. And you didn't make it?:( ). I have yet to have one leak. Any other gaskets that require a sealer - I'll use the manufacturers recommendations.
Depends on the gasket. Valve covers, High Tack to glue the gasket to the cover, thin coat of silicone on the head side. Intakes get a bead of hylomar around the intake ports, thin coat of silicone around the water jackets (Both sides). Water outlet gets a Victor tuff-cork gasket with a thin coat of silicone on both sides. Header gaskets...Victor Nitro-seal gaskets wiht a bead of ultra copper around both sides of the port.
just my .02
Copper Coat spray for head gaskets. Permatex #2 everywhere else.:D Every time I have tried RTV I ended up with a leak somewhere.:mad:
It takes the same dance to get the part back off too.. and it feels like a war too....:rolleyes: :LOL:Quote:
