I have been installing a turbo kit from hell on a buddies car for the past 2 weeks in my spare time. It was a new kit purchased from the manufacturer about 3 weeks ago. I have had hardly anything fit without modifying. I finally got done with the install and the car is smoking a good bit at idle and you cannot see behind the car under a normal cruise down the road. When you get on it a little, it fills the car with smoke from having the cutout open on the downpipe. The car is all original 94 with only 90k miles and had no issues prior to the install. Does this mean the turbo seal is bad and letting oil in the downpipe? It smells like hot oil the whole time it is running in and around the car. I dont see oil at the end of the exhaust, but have not pulled the downpipe back off yet as it was hot and I am sick of looking at this car due to the crappy fit of the kit. Should I see oil in the exhaust housing when I pull the downpipe if the seal is bad? I want to puke just thinking about having to work on it any more. Any help is appreciated.
