Hey guys, doing the timing cover now for about the 3rd time and this time with a brand new timing cover. It seems like everytime I use silicone I have some type of issue with leaks. Is it acceptable to use no silicone at all and just go with the paper gaskets alone or is that not recommended?

I used silicone on my W/P. The builder put the T/C on, so I can't remember off hand if he used silicone or not.

All silicone is not created equal. Lots of folks have trouble with sealant-X getting hard, deteriorating through heat cycles etc.

I've had nothing but success with the permatex cheeze whiz can:



I've used it for everything from making a plenum gasket to an oil pan gasket (and yes, timing cover and water pump).

I'm sure that other sealants exist that are as good but this is the one that's impressed me over and over.

this plus a billion; that stuff is no joke

I used it for my water pump and timing cover as well. Zero leaks and it was my first time doing it.

Plus 1 on the ultra black. Also the Napa "good stuff" in the tubes for caulking guns I hear is awesome stuff too

When I tore my brand new engine down to swap a cam, I noticed the Rick used the gaskets with some ultra black lathered up on both sides of the gasket. I replicated that when I put it all back together. Seems like a logical way to seal it all up.

People have also mentioned having great luck with the Permatex water pump sealer. Seems like the only thing that will seal those chrome water necks to the lower intake.

i use the ultra black on just about everything... not the cheesewiz type thought. i just put a thin beat around the edge and run it around with my finger. place gasket on... another thin bead... no leaks... and its not bad when you go to replace the pump. the silicone comes off pretty easy with a razor

Buy high tack sealant in a small metal can with built in brush, it is purple highly sticky sealant that will permanently seal your WP paper gaskets. Silicone never stays put because of its slippery nature and will end up in the water or oil eventually. If they would just make decent WP gaskets we wouldn't have to use sealants on them. Also make sure the two rear wp cover bolts don't hit the timing chain cover or you will have leaks.

I always use ultra black, no problems. I also use a gasket spray to get the gaskets nice and tacky before I lay them down. Never have any leaks.

Ultra black, blue or red here as well. Depending on application.

That's awesome! I've used Permatex, but always in the little tube. An aerosol can is a brilliant idea.
