For some reason the 22r motors have a lot of exhaust pressure. Try driving one with only the manifold and down pipe. That shit is loud and disturbing, I'm not a fan of cackling 4 cylinder exhaust, so I put a cheap cat. in front of my dynomax helped out a lot. It solved the annoying burp when shifting gears and helped out on the bottom end of power.
Phatty, you said you smell oil? Is this at start up or even after its warm? Have you replaced your head yet? did they put new valve seals in?
