I have a '91 TSi AWD that I rebuilt the engine in.

2G pistons
big rods
BS removal
head rebuilt
3000gt vr4 fuel pump
no fuel control

Problem is that since the rebuild, the car smokes a lot. The engine has less than 200 miles on it since rebuild. It was down with a blown ecu for quite awhile and the gas in the car is about 8 months old. I know I am running rich, but also believe that there is some oil in the exhaust too. I dont know if I am burning oil from somewhere (head was rebuilt, HG is good, turbo is good) or if it is simply all from being way too rich. The vr4 pump is a pretty good upgrade, and the ecu hasnt figured the fuel trims out yet, I am sure.

I just dont know if anyone else has any ideas on what the smoke problem could be. I have a video of the exhaust. In the video I revved up to ~2500 rpms two times. Here is the video, please <right click> and <save as>

I do thank you for all your help with this Ty, I just want to get any and all possible ideas. ;)
 
i dont know about 2g,s but on 1g,s the middel bottom stud for the exhaust manifold goes into a oil gallery in the block. just take that stud out and put some permatex should help out some.

That is a good point. I did forget to use hi-temp rtv or something else to help to seal that. I dont know if that would be a possible cause of all the smoke I am getting, but It doesnt hurt to fix it. :)

Thanks man.
