Oil found in the drivetrains according to the mechanic. Possible? Please advise. Smoke visible four years ago then disappeared until recent maintenance: radiator, water pump, and timing belt. Help!

You need to go back to the repair shop and have them check it out. It could be anything in the engine. or It could be just left over. Oil takes a long time to burn.

I am a rookie when it comes to cars, so what do you mean by left over? Thx!

Hello, One possible explanation: the faulty turbo allowed engine oil to enter the exhaust system. If so, it could take as long as a 30 mile freeway test drive for the oil trapped in the exhaust system to burn off. But please be careful. Significant tail pipe smoke may also be sign of other serious issues. My suggestions is confirm the engine has oil and water, and is running cool, and if so, drive to a professional shop for inspection. Expect to receive an inspection estimate of 1 to 1 1/2 hours troubleshooting. Good luck, hope this helps, Andrew

Turns out nothing was wrong with the turbo; this was simply the mechanic's guess. He is willing to put original turbo back in. Engine definitely has oil and water plus runs cool. Ever heard of spraying dye and using uv ray flashlight to see where the oil might originate from?
