Default ok found my leak, which sealant....(need an answer soon please)

this is kinda awkward for the air leak, because of the big .12 gasket i need to use there is a little space beween my header and its gasket, which allows a small amount of air to end ad eventually get into my tank and lean my car out off and on

so what sealant would work best?


kinda in a rush because i wanna go buy the sealant and the hurry up and test it so maybe tomorrow morning i can take it out to race

Ultra Copper sensor safe, high temp silicone gasket maker manufactured by PERMATEX . this is the only thing that will work for sealing carbs.

Between the header and gasket on the engine will not let air into the mixture. If it is a large leak, then the worst it could do is spew exhaust oil onto the chassis, and lean out the mixture by having less pressure going through the pipe.

I know a TC3 owner here that had a similar problem, so try posting in the TC3 forum, maybe it is common.

use high temp silicon sealant and DO NOT use gasket.

the problem with gasket is that it will reduce in thickness and will cauze the screw loose and leaking.

Copper seal is for exhaust leakage or temp sealant I thought?? I use a stuff made by permatex, it's called gasket elimatinator. Its not a silicone base sealant. It's perfect for carb and back plate sealants. Any type of silicone sealant is a no, no, too me. It won't stand up to alky or nitro fuels,.
I thought silicone base sealants were only for only fixing holes in tin roofs.
You can use copper silicone sealant on the exhaust side. But, you should'nt have too.

TSR6- remember, as i accelerate that little hole will act as somewhat of a vaccuum, so if i get going speeding around and it sucks more air into the tank, then will eventually lean out the engine and cause the airleak effect, then will go away once it idles out

so whats the verdict on what i need?

gasket sealant would be suited for the job best becuase its sealing high pressure exhaust gases

I've also found that silicone "sealants" don't really hold up at all against methanol and nitro.If you're going to use something maybe a anaerobic(spelling) type sealant might work(rear cover) but i haven't personally tried it yet,as for the carb just a bit of rubber grease will do the job.
