1998 Audi A6 Quattro. Had a cam cover oil leak that damaged the timing
belt. Replaced belt under an extended warranty. Now the car blows lots of
visible smoke out both exhaust pipes right after starting the car. Smoke
pretty well disappears after about 30 seconds, but not completely.
Looks/smells like oil smoke. If I shut the engine down, and immediately
restart, the smoke comes back for anothe 30-60 seconds.
What could be causing this? Was something not done properly when the car
was being repaired?
