I have some homework to do to diagnose this issue. I have some engine experience but I am no master tech, more of a part swapper myself. I have some friends that know their stuff so I will need to rely on them but their schedules can be tough so help may be limited for now. In the meantime, I am looking for opinions from your past experiences. I understand there are a lot of possibilities. This is a 2000 twin-turbo (Precision 62-66) running low boost. The engine was tuned just under 600whp at 6.5lbs of boost. Other than upgrading the necessary external parts for the twins all internal engine parts are stock. I can list all the parts added if someone wants the whole scoop. I went to the 1/4mi dragstrip this past weekend for my first try with my Precision Turbo setup and made a few passes. Once I stopped wheel hopping from launching too hard with street tires all went smoothly. On Saturday I made 3 runs. Sunday's first run was similar to my final run on Saturday, the car ran well with no issues. After helping a friend with his car for a few hours I got back in line for another run. While idling for a few minutes as the line started to move I noticed smoke behind the car. I immediately got out and noticed it was from my exhaust. I turned the car around and went back to the pits. Unfortunately, it was already late in the day and there wasn't time for in-depth diagnosis as I had a few hours to drive to get home so with much disappointment I loaded the car on the trailer I borrowed and came home. Many thoughts passed through my head as I drove home. I really thought that maybe the problem had something to do with the scavenger pump for the turbos. At least I was hoping it was that simple. Now that I see it is just smoking from just the right side and I can hear the scavenger pump running it is highly unlikely that is an issue...That said, I have not done much more to diagnose. Mostly due to my work schedule. Here is what I know..I don't really see smoke until the engine is coming up to temp. The warmer the engine gets the worse the smoke. I plan to pull the plugs this weekend and look for an individual cylinder concern. I am hoping to have a friend come over to do a compression test as well. I guess am I am reaching out for help too soon but I am looking for ideas on maybe the top 3 or 4 possible issues to focus on. Does anyone else have any experience with a similar smoke situation? Just to note the engine has 20k miles. Please ask me anything you feel is relevant. I appreciate any help or recommendations the group can provide.
