Re: Need help on my 4.6 head gasket/ overheating not my 64
no water in the oil, or steam in the exhaust. ran for 20 in the garage, with the cap off the expansion tank, no bubbles so far. no other leak except on the intake just under the nipple at the heater hose. definitely cracked.Ordered the PI swap intake kit from blue chips in indiana.
