ok guys i did a compression test when i first started working on my car, but i did not start my car and let it run a little before i did it i was told i could do it cold, well tomarrow i plan on doing it again. but the first time i did it was i got 124 on cyl 1 and the rest were in the 140's. so i called up a shop here in town and they said it was good. but every one is telling me its the rings. but when i redo the test i will let the car run a little before doing it. but lets say the one cyls is 125 do i put a little oil in it and see if it raises it and if it does what does that mean??????
