I found out what is was....my head gasket AGAIN!!....I dont feel like dealing with changing it again...i guess it over heated because they was ait in the motor and i thought it was filled up all the way and it wasnt....and im guessing the reason it dont wanna stay on is cuz the gasket is blowen and there is no compression..im so pissed now im thinking about selling the motor with the jrsc...idk what the hell to do
