the starter bolts into an area where there are no water jackets or anything near it. It could be the freeze plug right at the starter or a head gasket maybe. best thing is to get it hot and have it pressure checked to see where it's coming from. It could also be coming from the intake at the rear and leaking down..... that's why to pressure check it and pull the engine cowl off to get a good look at back of motor.
