Exhaust Seal Problem

[VinceDizzy]

Hey! I got some CPI's a couple of trips ago. They're great except for one problem. The o-ring that supposedly "seals" the exhaust, the one that sits in between the cylinders exhaust flange and the headers, always gets blown out? I dont know how messy liquid exhaust seal is? Or if anyone makes any type of high temp exhaust tape to wrap the flanges with to make a tighter seal.

 

-thanks

What o rings are you using? All you should need are some thicker ones. I used some out of a cometic gasket kit and they worked fine.

Yah im using the ones form the complete cometic set. So "they" do make ones that are thicker but not a bigger diameter?

I had that problem with an aftermarket pipe on an old YZ several years ago. I ended up using some JB Weld on the seal, and it worked great.

 

In fact, it sealed so well that I had to pry the pipe off when I rebuilt the top end 2 years later.

 

Seems like a desperate move, but it worked for me!

you got me thinking about doing that...I have a bad exhaust leak too...

I think all pipe manufacturers ought to put double o-rings in the header pipe.

i just used high temp rtv silicone.

 

make sure your exhaust flanges are clean of all oil and the pipe.

 

then apply a nice thick bead of silicone and put your pipe on and let it set for 24 hours atleast.

 

i know its really tempting to fire your shee but if you don't want it to leak you will wait.
