When I was dyno'ing I noticed the radiator cap was spitting just a lil coolant nothing to big and only one of the runs. Besides a headgasket sealing problem can air pockets in the cooling system have anything to do with? My heater hose sorta ripped (not blew) the night before i dyno'ed because of the hose clamp being so tight. I didn't have time to properly bleed the system so Im just debating to retorque the headgasket!?
