TO SEE IF EITHER IS BAD, CHECK THE COOLANT, IF IT IS A DARK DIRTY GREEN COLOR, IT PROBABLY HAS OIL IN IT, OR DRAIN THE OIL, IF IT IS MILKY COLORED IT HAS BEEN CONTAMINATED WITH COOLANT. IF EITHER SENERIO IS TRUE, THEN YOU ARE GOING TO HAVE TO PULL THE HEAD, THEN IS WHEN YOU WILL FIND IF IT WAS THE GASKET. SOMETIMES THE HEAD WILL BE CRACKED AND YOU CAN ONLY TELL WHEN IT IS WARM FROM THE ENGINE RUNNING, THE ALUMINUM EXPANDS AND THE CRACK OPENS UP,WHICH IS HARD TO SEE. THE ONLY WAY I KNOW TO BE FOR SURE IS HAVE A MACHINE SHOP CLEAN IT UP, AND DO A "TANK TEST"(FOR LACK OF BETTER WORKS)
