White smoke coming out of tail pipe; replaced the turbo but smoke still emits.

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.

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
