You may be able to run once started with low compression. At this point you may want to do as suggested with a little oil. If compression does not rise on that then inject some air to see if the valves are sealing as well. Less than 200 pounds per cylinder is not really acceptable. Even 200 lbs is poor. A diesel really is not happy starting at 150-180.
All you seem to have is gas engine compression numbers on a diesel. Yes you could line up your bottom pulley at zero and the top cam alignment marks to check the chain. If the low reported milage were true the car would have had to have been sitting out of service a lot. That could cause this problem as well as excess milage. The indicated milage is only in the magnitude of 2,000 per year.
