I have a 53 3100 with a 216 and 3 speed that is just a yard driver that I start and move occasionally. I started it today and found that it would grind when I tried to put it in gear. I shut it off and discovered coolant leaking from the drain hole in the clutch inspection under pan. I'm thinking that the clutch disc might be rusted to the flywheel. Does anyone out there know if there is a freeze plug on the back of the head or motor? Hope I don't have a cracked block. I have kept antifreeze in the radiator, but did flush out the cooling system a year ago when I bought the truck. It had sat for years. George
