with a coolant pressure tester connected to the cold engine start the engine
if it gets to 14 pds in the first few minutes then the inner  head gaskets
are leaking combustion pressure into the cooling system and why would you
run an old pressure cap if you suspect the cooling system is over
pressurizing itself  BUY NEW
