exhaust sealant

[john_3.0s]

for about 2 years ive been trying to get the exhausts on my capri sealed to the manifolds properly. Its a flange joint and ive tried different size sealing rings and more exhaust paste than I can remember but I still cant get them to seal properly no matter how tight they are done up.

 

Before i cut the flanges off and make up a sleave to go over the top of them are there any really good exhaust sealants out there? maybe some kind of silicone based sealants?? Im getting really p!ssed off with them!!!!

Ive always got a tube off kwik fit the type u put in a gun and make sure u got it really clean no old crap left on it and u need to run the car up before u do it to get the exhaust really hot or the water in the exhaust will make the sealant run off and dont use nylock nuts and u got to do it up even.

silicone sealer or even tiger seal, exhaust paste just drys out and then crumbles and fall out which then makes it loose

tiger seal, didnt think of that ill give it a go

Do what i did mate , cut the flanges off and weld a flared pipe on to the manifolds and slide them on the centre boxes then use a normal 'U' clamp , no more problems , the aftermarket ' rings ' never seal properly..

Thats exactly my 'plan B' !

Ive tiger sealed them this eve so let see how that works out, im letting it go off before i fire it up so fingers crossed!

I know a few people that used sika flex to seal exhausts but is a nightmare to get apart at a later date.

well the sealer hasnt worked all that well, its better but still not right. Ive got to do the rack at the weekend so think ill get the manifolds off and weld them up as suggested so there done for good. was hoping to make chelsea this weekend but doesnt look so likely now (
