1998 4.2 v6 blown head Question (help)
so first the problem was one of the heater hoses snapped off the heater core connector. While diagnosing the problem i noticed there was amounts of rust throughout my cooling system, so i just went ahead and got both new heater core pipes and both radiator hoses, and a new thermostat. i was gonna clean and flush the system. After successfully putting all the new stuff on and the truck back together i filled the radiator up the just water to test it, and once i turn the engine over it runs shaky and ruff the water in the radiator bubbles instantly with the cap off, the white puffs of smoke coming out the exhaust, the engine oil is milky, and theres white smoke coming out of the engine oil filler tube.
