check...the engine runs great. However, I am concerned about turbo replacement in the next 30K miles or so...so I did previously mention here in the Forum that I would be doing a compression check some time soon. My thought is...if I am seeing compression issues maybe I should do an engine rebuild at same time turbos are replaced (since turbos can be replaced so much easier with engine out). The car has 220K miles on it at this time. Regards, Jim
