Car was making a knocking/popping noise at random times. Wife took it in to a local shop, no problem found after many miles and a few days of troubleshooting. I had them change the oil as it was a good bit overdue. After the oil change she picked up the car and began driving my son to football practice. The car began smoking from the exhaust, by this time the shop was closed for the weekend. She kept it parked until I got home three days later. I check the oil level was on the high end but good but it was very black. Air breather filter was a little dirty but no oil. Then I pulled the tube from the PCV valve to the intake manifold and oil poured out, a lot of oil. I removed the PCV and air/oil separator, they were completely full of black oil. The car goes back to the shop and they tell me I have blown turbos and it would be $2600 to replace them. I trust the guys at this shop but it is funny to me that the turbos never leaked or made noise before we brought it in. Actually they still don't make noise and still seem to be putting out boost. Any advice on how to proceed would be greatly appreciated. I can do most work myself.
