cam end plate sealant

[MichiganMat]

hey guys-

Im in the process of replacing the gaskets between the heads and the cam end plates and I read in Waynes book to use Curil-T to seal them up. I've also read around this board that Curil-T doesn't exactly grow on trees. Is there a local store that I can buy this stuff at or is there a suitable replacment that will work? Some people have mentioned "yamabond". Is there any reason why silicon RTV wouldn't work?

Also, the book says to put in the cam chain box gasket (between the box and the case) dry with no sealant. Any reason why I wouldn't want to seal up the bottom of these gaskets with something? Oil leaks are not my friends, they must be defeated!

I use, and I believe Tyson at TRE also uses (please correct me if I am wrong) Hylomar. It is readily available at local auto parts stores. I think the Hylomar that I use is made by Permatex.

Curil-T is available from Pelican (PEL-246948). Curil-T and "Yamabond" (ThreeBond 1104) are both non-hardening. I suppose that lets things move around a little and reseal.
I used to use Loctite 518 (available at your local NAPA) on the cam thrust plate gasket but the last couple of motors I've been using that copper "high tack" spray the John Walker has mentioned. The high tack stuff is convenient because it will hold the gasket in place during assembly. If you use the 518, you should rub it into the gasket before you put the gasket on.

You don't really need anything on the chainbox to case gasket.

Absolutely, positively avoid RTV any place that is exposed to the internals of the motor. All it takes is for one RTV "booger" to break off and get caught in one of the many pin holes that oil goes through to ruin a motor.

Mat:

You can also install all these gakets dry, especially on smaller area German-machined surfaces like these. If things are flat and clean and you use quality gaskets, no sealer should be needed. The factory used none, as far as I know.

If I use sealer (on the US made stuff with tin pans and covers etc.) I use high tack by permatex. It also stays soft like others mentioned above. I second not to use RTV anywhere on the flat six.
