exhaust manifold leak
 

the oem exhaust manifold gaskets have a lip on the corners of them. if you put an aftermarket flange onto them, won't you get a leak between the ports? that seems to be what's going on for me

help? :p

to be a bit more clearer:

the very inner ring should be about the same height as those lips

once crushed though it may leak its best to use new ones if theyre flat.

And whoooo boy those things ain't cheap :)
