Majority of my boost leak problems as of late can pretty much be attributed to my GT-Spec header and uppipe.
About a month ago, I put in a capful of ATF, per 2fastnturn's recommendation, to find where my exhaust is leaking from. I dont think I used enough ATF because the car was suppose to smoke like a mofo and it didnt. Somehow the ATF just ran thru the engine and out the exhaust clogging up every leak there was. That's why my car was running very well during the S2K cruise
So I finally get off my butt and take the turbo, intercooler piping, subframe, header and uppipe off my car today. I noticed the following:
1. There's some carbon deposits coming from the slip joints on 2 of the runners on the header.
2. There's soot where the uppipe connects to the header(GT-Spec recommends 2 gaskets instead of 1).
3. There's soot at the wastegate flange(Pang did it! But he'll fix it).
4. There is an EGT bung welded in there by GT-Spec which has a crack all the way around. I only noticed it because ATF has leaked out of the crack and left a black mark around it.
Tobi, I think Vibrant and GT-Spec headers are one and the same.
