Cam phaser sounds like a diesel when they are going bad. I haven't got that issue yet. Thank god haha. But I think my manifold might be cracked or have a hole in it. Cause it does echo through the exhaust. My stock manifold does look pretty ****ty (rusty)
do the seafoam test like i was talkin bout on txt. if you have a leak, you will EASILY notice it, even if its a pinhole. pop the hood and start lookin. if you only get smoke out the tailpipes, then unfortunately its not a exhaust leak... and i'm almost positive its not your cats.
cool. glad you got it pegged down finally. are you just gonna fix it when you rebuild your exhaust? or get to it before then?
LT HEADER FTMFW!!!! I'm puttin my Pacesetter pair on this weekend, if I can find a 3" to 2.5" reducer
