normally i would say you guys were right and x3 on the above coment but i just recently had this problem and there was nothing wrong with my piston. It turned out to be my #2 oil pump that returns the oil back into the resivior was not working so all the oil would stay in the motor causing major blow bye , but once i fixed the pumps everything was good.
