I installed a 5" turbo back exhaust the other day. (4" downpipe flanged to 5") I know it defeats the purpose but I wanted a 5" and found a good deal on it. Anyway, after a couple of days it looks like there is a light coating of oil on the inside of the tailpipe. Is my turbo going, seals, blow by? Any thoughts?

Thanks.

Its nothing, its just the oil that is coated on the inside of the pipe when they bent it. Give it a couple more days and it will be black soot only. If not you got a problem.

I had the same thing with my new pipe. Within 3 or 4 days it was dry.

Ditto on not being worried yet. I can understand when you do something to a perfectly good truck and it looks like it isn't working right.
