Thread: gaskets and silicone

Tweet

I get razzed everytime I post this info ,but I use aviation gaskett shelac on stuff like that.It seals pretty good,only downside is old gaskett removal.

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

permatex form a gasket aviation no.3 i use many things other then this 3m weather strip cement works good to hold gastets down and OMC typ M .hylomar and teflon dope on studs and bolts .i try not to use sillcone much if i do i only use it on one side of the gasket if like a oil pan gasket the sillcone will push out the gasket when you draw down the bolts so i will use 3m cement on the block side to the gasket and then go around the oil pan rail with RTV then draw it down but not to tight then let set up over night then a 1/2 turn more

Pat, you need me to teach you how to do those gaskets, my style. Never had any problems. It takes years to perfect the method.

THANKS i do not dance .i just do a irish jig well i never had any leaky oil pans the cheap pans some times fit up is not to good that were you need the RTV i really do not have any problems if you get your hands on OMC type M you will need dynamite to get any thing off you glue down with it .

I really haven't kept up with the times regarding sealants. I still like good old Permatex # 2, and Hylomar. We just used RTV on my Kids engine because he insists it is more modern, therefore better. I'm still in the dark if that is really true or not. And yes, I always use gaskets, except on the front and rear of intake manifolds, where I put a bead of RTV.
