My 993TT has 45800mile,I drive it at least one a week for an hour ,I dont drive it hard,but occationally I rev it to 5500rpm to clean up carbon built ups. The exhaust had never smoked at start ups.Anyway My car had lower valve covers replacement service done recently.And when my mechanic removed the turbos ,there were 95mi of oil drained from driver side turbo ,but there were only 25mi of oil drained from passenger side one.He said it may due to the car was parked on unlevel ground prior to his work.I understand it is not supposed to have significant amount of oil in the turbos .So Is this sign of problems?
Thank you for advices.

Put in the 996 check valves on the turbo oil feed lines...thats the fix

911/Q45

If the oil was in the turbo sumps, it's normal and the varied amounts could be due to jacking angles. If it's not smoking, I wouldn't sweat it. Check valves from UMW would be a great "while you're in there" mod.
