my truck has been sitting for a little while because i was out running it and it died so u went to put a clean glow plug in and when i put the glow plug in it lost compression and the glow plug was tight so i took the engine apart and checked the piston and sleeve and it was fine so i took the plug out and there was metel shavings anround it so i checked the underhead and it was stripped out so my truck will be back up and runnin soon. thanx site jester for posting the tuneing guide cuz now i know how to toon my truck so all us NW bashers will have to get togther and go bashing
