i was lucky enough to get to use a really nice boroscope to look inside my engine today. the backs of the valves were very clean and there was actually no carbon on the backside of the valves. now on the face was a different story . all the intake valves had a layer of carbon on the face. some were a little wet from the oil burning in the cylinders, but they all togother looked good. the pistons look pretty good, and the cylinder walls look great as well. i think i am slowly narrowing it down to my turbo being my smoking culprit. tommorow im getting my car towed to my brother in laws house where i can use his enormous shop and lift :smile: this is the beggining of a long journey.... btw do you guys think i should replace the hg while i have the engine stripped down to just the block and head?
