Having problems with your 1999 Pontiac Grand Am GT ?
2002 grand am 3.4l 1 newhead have compression only on cylinder 3 and 1 and 5 zero compression tried putting oil in no luck?
Well thats good. if you put in oil and there is compression that tells you that your rings are bad and neeed rebuilt. i would check your timing, its possible that the exhaust or intake valve is open on the compression stroke letting the air escape.
