97 gtx no compression

[billy62]

My 97 gtx ran fine yesterday carried it out today ran fine for about 5 minutes ,then started missing ,got it home and found no compression on back cylinder.Is there anything besides a hole in the piston that will cause this? Have great compression on front cylinder,hard to believe ran fine one day and then blow craps the next day.

you might have a piston ring problem you can pull your head off and see whats going on..
