Hey, has anybody ever put high temp RTV under a band clamp to get it to seal better? It was sealing perfectly but I had to remove it and I guess I didn't get it back on in the same position and now it leaks a little bit.

Thanks

 

Why not just spend like $15 and get it welded?

 

Because then I won't be able to remove the exhaust from the car, which is nice to be able to do when changing the clutch etc..

 

Ok, I see what you're saying... but no, I wouldn't use RTV. I tried that, and it blew it all out in less than a week. Maybe try that exhaust patch tape under the clamp. That would work much better.

 

permatex ultra copper


not another brand of ultra copper

not another type of permatex

permatex ultra copper

 

looks like this:

 

i have used that on temporary exhaust connections to seal them up when welding wasnt an option and it works well. i always had to clean it off when i made a permanent connection, never had it blow out. i agree completely, the Permatex Ultra Copper is the stuff to use.

 

well u said you dont want to weld it but you want the seal of a weld, you could try JB weld. this part wont have much stress on it, however i dont know how easy it is to get the stuff off. never tried that.

 

 

you can NOT use JB weld on a exhaust system.. or in any high heat area.
