Hey all....I have a 50' 235 and have recently noticed clean coolant on the top of the block on the dizzy side kind of along the head gasket. I checked the thermostat and water pump seals and do really see anything wet. Could there be a head gasket issue on this side? The motor runs great and doesn't smoke so I don't think anything is getting into any combustion chambers. Is this a common issue? It's not alot of coolant since the level hasn't changed much at all. Any ideas? I don't want to replace the head gasket if I don' thave to....Thanks!
