Hy Josh_51GMC, have you changed the oil since you started your engine? If you have and it has turned "milky", a blown head gasket is only one of the possible causes. Have you noticed a loss of coolant? When the engine is running at operating temparature remove the rad cap and look inside the rad to see if you can see any bubbles moving by the filler neck. The block may also be cracked, good luck.
