Now they use another method based on liquid forced by the plug(s) hole when the piston is at BTC( bottom dead center ) , while the valves motion is stopped by removing the corresponding rockers . Then they mesure how much liquid is pushed out of the cylinder by bringing the piston at TDC ( top dead center ) Am I not right ? Jo Goodtimes , France . airborne radar tech live free or die
