even if motor is out of car, just hook up a battery to the starter and still check compression....Anyway, you are stuck with it now...as mentioned above, blue smoke is an indicator of bad rings and with those compression numbers I would think the engine should be missing....#2 cylinder is not working at all....and all 3 of those bad cylinders are on the same bank....they make products to help but it is just putting lipstick on a pig

Good point regarding the Starter. Ill keep that in mind for next time. :) Does not sound or feel like its missing but Im by no means an expert. I'll give the lipstick a go and see what results I get for curiosity's sake if nothing else. I'll get the other items on my list sorted out first then come back to the engine when funds allow. The car wont be moving much now till Spring as the weathers turning and its always wet out now.
