So I took out my nova today and drove it til it hit operating temp, then it just kept climbing to over 240 degrees.. I was very close to home to home so I took it back to garage. I open the hood and noticed the valve cover breather/oil cap was hissing steam like overheating... I checked the radiator and it was missing 2 gallons of coolant..then I check my dip stick and saw the oil level much higher then normal and it was like a milky mud substance. I also then took out all my spark plugs to see if I had water in there, but all plugs were gone dry.. what u guys think bad intake gasket? Oh and by the way its bbc dart motor 548 with brodix heads and cometic head gaskets.
