Permatex High Temp

[RezoD]

I need a new gasket for my cylinder to block... But I don't want to buy the 40$ kit to just use one gasket. Can I use something like the Permatex High Temp silicone, made for engines that see up to 500* of heat? or will it seal just as well as my non-sealing gasket I have now? :p

P.S.
If there's any way to put a rush on this post, please do! I'd like to reassemble my motor today, and be riding by the weekend!!!

i have jeard of people w/ 400ex's not using a base gasket to lower the squich volume and raise compression, so i would assume it must be possible. i'm sure they used silicone in its place to seal the surfaces

And it will change your cam to crank timing,but you can dial it in with an adjustable timing gear.

Where can you get an adjustable timing gear?

[RezoD]

Using no gasket (Just the Permatex) worked perfectly, for those who may have had doubts. I have no more leaks, and the quad runs perfect.

My timing may have been advanced another degree or two, but I honestly don't notice a difference between having the gasket and not. The extra compression didn't make any difference to it performance wise (not that I can tell anyways), and neither did the timing.

Just wondering, how much did you use? A real thin coat?

[johnsls]

When my engine was being taken apart (partially) we noticed a lot of sealant that gummed up everthing. Probally just read the instructions but I think a thin bead should work.

Why not just use the oem gasket so your not changing the compression etc....??????

[RezoD]

I personally did exactly as the directions said. I believe the bead was supposed to be around 3/8" wide by about 1/4" tall... Around all the bolt holes and ports. Any ports that I saw, we used pipe cleaners to take up the space so no sealer could get in there. Tightened everything down, then removed the pipe cleaners.

I didn't use an OEM gasket because of the price... A top end kit was 50 bucks, as opposed to a 5$ tube of Permatex.
