i've been driving my car around lately just a little before I was going to get the tune done and finally got a new compression tester due to the blue smoke coming out the tails. After checking it, i only have 60 to 70 in each cylinder. look like i'll have to pull it back out and redo the rings. i've tried using the old marvel mystery oil trick with no luck to try to get them to seat. anyone have any other ideas on what to try before i pull her back out? it has 120 miles on it.
