I had a turbo seal blow and ended up with probably 1.5 to 2 quarts of oil in the exhaust. I was going to let it burn out but decided to clean it all out. Before I cleaned it out the car was running and some I noticed an oil leak right at the v band clamp to the turbo on the exhaust side. Now I'm wondering if the seal is blown again on the turbo or could it be sucking some of that oil in the exhaust back up to the flange??
