which timing chain cover gaskets get sealer?
does the t/c cover gasket get gasket sealer on both sides? same question with the water pump divider and two gaskets for the water pump. Yesterday i put Aviation 300 on both sides of my t/c cover gasket, the first water pump gasket and then only on the back side of the second water pump gasket, so the divider was sandwiched with the goo, but i put nothing on the back of the water pump itself. should i have done it differently? thanks. no question to basic here right.

I used Gasacinch on the paper gasket between the timing cover and the block (make sure BOTH surfaces are flat). I use Ultra Copper lacquer between the gasket mating surface for the water pump, the water pump baffle and the timing cover. Aviation gasket sealer is also a good choice. I'm NOT a fan of RTV.

I usually use no gasket sealers except in about three instances! 1)The manufacturer insists it is required! 2)The surface being sealed is pitted or sheet metal that can bend or warp! 3)The gasket has multiple parts that must be joined such as where the timing cover and oil pan meet!

I goo both sides on all cooling system components - wp, timing cover, tstat housing, tc to intake mating surface/grommet.
Permatex ultra black or gray stuff. I don't go full-stupid with it, but old engines have many pits and irregularities that need some "help". I am also a "go" guy, not a "show" guy, so seeing a little squished out rtv doesn't bug me. I am very sparing, tho, when it comes to oil system gaskets so that I don't get a piece of rtv in a pump regulator ball, etc.

RTV shouldn't be used ON a gasket. It's sometimes ok to use RTV instead of a gasket. I'm not too fond of it even then. There's dozens of appropriate gasket sealers--Gasgacinch is wonderful, as is High Tack, Copper Coat, Hylomar, Permatex #1, #2, and #3, Indianhead shellac, and many others. |

While RTV offerings have become better and better over the years, it seems that Gasgacinch has either ran afoul of either the EPA or the company bean counters. It's not nearly the product it was a few years ago. Now it is a white milky liquid that seems to disappear into the gaskets with little to no holding power. Old stuff was like a heavy duty rubber cement that worked great.

Permatex ultra black is good stuff and the only RTV I'll use. When I want to make sure a gasket seals and stays sealed I smear the ultra black on with my finger as a very thin coat. Used like this it's like glue. Depending on what I'm assembling I'll use it on one or both sides of the gasket. If I just want to glue a gasket in place I'll smear it onto the part then put the gasket on the part, lining up all the holes and let it set up for a minute or two before installing.
I'm talking using a really thin coating of it, so thin that it won't squish out hardly at all. Just smear it on with your finger 'til you get a paper thin coat of it. If you let it set up a little before installing that also prevents it from squishing out. It does a great job of sealing irregular surfaces and pitting and is coolant, oil, and gas resistant.

thanks, i feel just fine with the avation 300 after reading about the demise of the others. i have another question and that is that all the bolts i used only go about 1/4" into the block or t/c cover, in the case of the water pump. it was enough for me to properly torque them down, so would it have been better to have used a longer bolt?

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
