I recently had my engine rebuilt for my XT by a reputable shop in Michigan. What I didn't realize was they replaced the banjo bolts in the oil line on the right side with plugs for testing. Needless to say I installed and ran it several times up to tempature checking for water and oil leaks including a 10 mile easy drive locally. Besides ruining the turbo bearings the cam timing device was without oil. It now appears I have quite a leak from one of the cam seals maybe on the right side. What other damage could have occured with no oil being delivered to that line on the top of the cam?!!!!
