Title: Can pre-O2 exhaust leaks cause problems on these cars?
Post by: JoeDellio on June 30, 2009, 07:39:29 PM

Just wondering if it is adding to my problems, I seafoamed my car, and it appears I have a big leak at the manifold to head.

I'm not sure.  I'd figure it would, but I have no proof one way or the other.

After looking more closely its only from the outlet of the header, I dont think it would cause that much of a problem.

Well its probably not helping anything.  Just throw in a new gasket.  Guess that could be more difficult with rusty bolts.  Just be ready with a torch and a can of PB blaster.  Also it helps to turn the rusty bolts a bit tighter before turning them loose.

Ill probably do it, the bitch about it is that the manifold to head are crammed in there with my damn AC lines in the way. :mad:
