exhaust gasket ideas
 
Since all of the gaskets i buy are a freakin joke. burn out within like 3 days yes i have got aluminum ones. But i'm wondering what would take the exhaust gasket? I was thinkin of gettin a fairly good size chunk of asbestos? Gutting it into the formation of a gasket and using that any suggestions?


Thanks, Evan

any ideas?

asbestos is sandwhiched between the aluminum on those one you can get at the dealer, like 7 bucks a pop though, but what your describing should work good since asbestos has a high heat capacity, but I'd use a mask when taking those sucker off, and or puting them on, that stuff is extra bad for you..

Oh, come on....

A little absbesos never hurt anybody. I used to eat paint chips when I was a kid and I turned out fine [involuntary twitch].

Yeah, wear a mask when dealing with that stuff.

If you keep blowing out gaskets, then one of the mating surfaces is warped and should be machined. Also, don't over or under tighten.

I had the similar problem with the Bonez Racepipe. The gaskets would always blow after a months usage. I found the flange found on the racepipe wasn't flat and warped. So I welded off the warped flange in return for a 6mm stainless steal flange. I haven't blown a gasket ever since.

Im not sure its blowing the gaskets in the first place, it mught just be leaking from a bad flange surface.

I just fixed my whole headache by getting a new manifold and mounting the catalytic conveter by itself first and tightning the bolts, and THEN connecting the y-pipe.

Made for a nice flat surface.

damn dude :P i need the car sounding as good as possible. Could an exhaust shop grind it down? what kind of tool would they use?


Thanks

Most machine shops will be able to easily do it if you bring them the part. Doubtfull that an exhaust shop has the equipment necessary.

DC350 12-26-02 02:25 PM

damn, i have to bring them my manifold?

Just do it. Belive me it is so worth it end the end. I went through alot of exhaust gaskets and headaches form exhaust fumes like you. I finally took a forum members suggestion and just got my flange machined and a nice flat new manifold. No problems since.

okay, here goes. I guess i will get my manifold ground down :(
