Finished my exhaust finally but I seem to have a leak at the flange. I just used the thin metal flange that Borg Warner supplied. I cranked it down to different torque numbers and it still leaks.

Just curious if there was a better gasket out there before I throw on the silicone


dang nabbit, this thing is still too loud with the exhaust on

 

and I seriously almost dropped dead from this E85

 

You need to surface the flanges flat. The thin steel gasket should work fine.

 

Do they warp or what? Who does that type of machining? Any machine shop?

 

Yeah, when you weld on them they warp especially with a mig. Any automotive machine shop should be able to do it.

 

right on mang...... I should probably have the flange on the engine machined too, huh?

 

deff wont hurt

 

I had mine done at a diesel engine shop big flat table used for blowers! Engine flange turbo flange and wastegate flange.

 

If it's not too bad and you have access to a nice belt sander you could get it done. If it is warped bad you will need to get it machined as stated.

 

Thanks Sean......... I don't have a belt sander so I'll just have it machined down. I don't hear a exhaust leak, just have fluid dripping out (E85). Running a little rich

 

omg u arent runnin rich u r about to run high

 

what

 

I have some multilayer T6 gaskets that a buddy gave me. I'll stick on in the mail for you if you want one. Let me know.

 

actually, I don't think it's the flange...... I've got millions of pin holes in my welding. I suck...... ***

 

HA! PM sent!
