If the turbo was the cause of the problem they might warranty it, but if it was a problem of the motor like a spun bearing that many of us have fell victim to, they don't have to.

Also, if you take your car to satan to try to get a new motor out of it, I would stronly advise you to put your car back to stock including using a different oil pan. Any sign that you had a turbo and thier gonna drop your car down off the racks and let you be on your merry way.

Good Luck.
