In reassembling a T100C which gasket sealer is best to use between the two cases which have just a metal to metal fit??
Also which sealer is best to use on the other gaskets, primary case, rocker covers etc, I'm thinking of using Black permatex #2.
Also the copper head gasket.....

Thanks for any input!!!

I have used loctite (I think it was 515 or similar) before on engine cases and primary it was really good never had a leak.
Rocker covers are generally good with just gaskets
Dont use anything on the copper head gasket but it will need to be annealed (heat to red hot and plunge into water to cool)

gasket sealer

I used Yamabond #3 on my old xs650, it seals good and comes off without much fighting.

no matter what you use, clean the surfaces cleaner than you would want anoperating room to be clean if they were going to work on you. If there is even a hint of oil on any surface, sealants will not seal.

fought a lot of leaks

Hi Folks-
I've always had good luck with Mopar gasket maker. The clear red stuff. Any Chrysler dealer has it, it's about 20 bucks for a good-sized tube, and most important, it's an anerobic sealer. No blobs running through your oiling system. Good Thing. Lacquer thinner or carb cleaner to clean the joints up and it's good to go!

Yamahabond is the way to go; been using it, ironically, since the days of my 1972 Daytona 500 (which I bought new). Great stuff, and it comes off easily, if need be.

Motocraft Gasket Maker Forme-joints

I just used some ford stuff named above. Cost about $14. Success on inner and outer trans covers and as I had no gasket, on the primary chain cover. I let it be overnight.No leaks. Says for use on alum and cast iron parts. Fills gaps up to .010. Does not shrink or migrate. Cures to a flexible seal after confinement of 1-8 hrs. Clear red stuff. I like it.Found out it is really loctite 518.

Three Bond 1130 (same as Yamabond) on metal to metal and (sparingly) on gaskets. For the head gasket I spray with Coppercoat. Make sure the copper head gasket is good and pliable--many of them are work hardened by the stamping process and do not do a good sealing job. Anneal the gasket before spraying with the Coppercoat.

Many years ago (40 to be exact ) I had my 650 cases and transmission apart and was wondering what to use putting them back together. The trans inner cover had a thin gasket and oil just ran right through it. The engine cases no gasket at all, just sealer. I was at auto parts with a friend and saw some new weird stuff made by Permatex and I believe it was even called ‘ the Right Stuff ‘
It was in a squeeze tube which came in a cardboard cylinder.
Since I was helping my friend he bought some for me to try on my engine cases. It was advertised like it was a silicone- type sealer but it was not. It had the consistency of jello with whipped cream and was rather runny but I found it was perfect for machined surfaces. You put it between two machined surfaces and tightened them up and it seemed to harden instantly under pressure.
I used it on my ( very leaky ) transmission case instead of a gasket and also on my engine cases. This turned my leakiest transmission into one that stayed bone dry. No leaks whatsoever from engine cases either. A few years later I used some on my Harley cases.
Now 40 years later I am taking apart the same engine and seeing what the ‘ stuff ‘ looks like after all these years. Upon opening the transmission case it looked as if I had put a paper gasket floating in space between the cases but it was really just the ‘ stuff ‘ . It hardened into what looked like thin plastic or where it just stuck to the case it looked like thin pink cellophane. I even have some sections of it that came off as if a piece of plastic gasket.
Now that I am looking for something to use again I look in the stores to find there is a Permatex sealer called ‘ the Right Stuff ‘ but it doesn’t look like the same thing.
I wonder if there is anybody else remembers that ‘ stuff ‘ ,it’s been a long time. 1980

Wow 23, I would love to know what that was. Problem I have with most sealers is dis-assembly. Been many cases and covers buggered badly trying to overcome sealant. Jon Bergland told me once, threebond only on one side and let it dry or you'll never get it back apart. I find it can still be very tight.
Your product is very interesting, I should be familiar as it's in my time but I don't recall.

Btw... Three Bond 1104, Yamabond, and mopar gasket maker are all supposed to be the same thing, but I'm not so sure.

Yeah, I wish I had some of it now to use once again. It was really weird stuff. It was about like some really bad toothpaste coming out of the tube. It didn’t look like you could do much of anything with it.
But I believe it did harden under pressure, like right now. Squeeze some down then take it apart and it is hard right away. That’s what I remember, now after 40 years I was afraid it would be permanent cemented together but it came easily apart and what was left chipped right off. Mostly fingernail. I have some pictures of it on my camera ( maybe later ) where it came off in large pieces looking like a piece of plastic gasket.
I think that locktite gasket maker stuff sounds like it could be similar.

The new Permatex "Right Stuff" is awesome. I have a Cub Cadet tractor that would not stop leaking from the valve cover gasket no matter what I tried. New gaskets, new gaskets with sealer, nothing would stop it from leaking. Bought another new gasket and used the "Right Stuff" as suggested by a mechanic friend of mine. Followed the directions. This stuff, you let it setup first before you put stuff back together, and it hasn't leaked a single drop since. Great stuff.
