Just bought my first twin turbo. Decided to do a compression test just to make sure everything was up to par and turn out my left bank is between 120 to 125. Right bank is slightly higher fluxuating between 135 to 145. I know the guy I bought it from said they did the 120k kit. So my question is could the guy who installed the timing belt possibly not know what he was doing and set the timing incorrectly? And this be the cause of the lower compression on the left bank? Any insight is greatly appreciated.
