ok, i tried pulling the sleeve out of my rs12s2, but its stuck, i heated it up with my heat gun,and i got it out half way, but no more, and since i didn't want to use any more force, i thought there was something wrong. It just won't budge now, up or down, the piston moves freely up and down, but the sleeve is stickin halway outta the engine! The engine has about 13 tanks on it. My dad suggested i wait until the engine cools down to room temp to move it back down, then heat it up again from that temp,and pull it all the way out, i also can't twist it either. please help! heres a pic to help you.
