I own a '68 M715 Cargo, all stock. Saturday I spent quite a bit of time trying to get the truck started. Ended up having to use a charger on the batteries. The truck started up and was running fine. Was letting it idel and went inside. 10 minutes later when I walk out I have oil spraying out from under the intake manifold. I shut everything down. No radiator fluid. I add oil and the truck starts right up. Oil begins spraying out again from under the intake manifold.
I'm thinking headgasket needs replaced. Would appreciate any thoughts, comments, or guidance for my next step.
Thanks, Howard
