Looking for help....I have a 37 Ford pickup with a 53 Merc Flathead. Its my daily driver which I put on roughly 200 miles a week. I took it out last night and as soon as I started out of my drive way I knew something was wrong. The engine was misfiring and seemed to want to stall out. I returned home and let the truck sit. When I came back out a few hours later there was a large puddle of antifreeze on the ground. I cant find were the leak is coming from though. Its is coming from the engine though, not from the water pump It is seeping down from somewhere (???) and then dripping of the leaf springs. Any thoughts as to what this could be??? I would think head gasket but its leaking when its just sitting......
