Hey guys, im pretty sure i blew my motor and need a little help. I have a 1998 GMC K1500 with a 5.7 vortec. The motor wont start, the flywheel is putting up resistance an we dont know what it could be. Compression is all over the place, some examples are 190 180 120 60 etc. #4 cyl is at 60 any help would be much appreciated, thanks guys.
