i took the valve cover off my truck and as i removed the bolt antifreeze started spewing out the radiator was not preesurized in fact it has not been run in 3 days or so. There is a pretty big puddle of antifreeze under the truck. i am kind of worried about this it is a chevy 235 and i want to know if it is realy serious and if i need to fix anything else while i am replacing the head gasket thanks
