1993 All Other Makes All Other Models Repair Question
93 GRANDPRIX 3.1 COMPRESSION LOSS.
Hi, you are NEVER going to take that plug out again?
Been really disgusted with mine before but not that much! But before that maybe you could look into a threaded insert for that plug hole. Not positive how it goes but think you enlarge hole and insert a threaded sleeve somehow. Try a search on rebuilding heads and you may get more info on this.
Just trying to help. hang in there, it'll get better. 8)
P.S. If you really are going to make it permanant
JB weld works pretty good!
