I believe the mechaninc is not sure of what he is doing. For this engine with timing chain to jump time, the engine would most likely be turned in the reverse direction. If the chain had jumped time by itself due to bad chains, you most probably would need a new engine.
After rebuilding the engine, the question of no compression on one cylinder shouild not arise.
Loss of compression can be due to leaking valves or bad piston rings and these should have been taken care of when rebuilding the engine.
