My 59AB started leaking what seems to be at the bottom or rear of right head, no water in oil and not in exhaust at least there is no white smoke, I would like to get by while the weather is still good. Is there any suggestions as to a product I can add to stop the leak until I can pull it apart this winter and will not clog my radiator ? Thanks, rick

If you "just want to get by" until winter, why not just keep replacing the coolant until you can fix it properly? Water is best, as it has less tendency to leak as does anti freeze. Adding quick fix products can gunk up the system if not used correctly. If your motor is relatively fresh, try re-torqueing the head bolts. If not fresh, the head gasket may be going bad.

That kind of leak can often be from a "wet stud" that wasn't sealed when last installed. Check carefully to see if there is any leakage. To fix it the head must come off and the offending stud unscr*w*d from the block. We use a Permatex sealed on all studs at our shop. While you have the head removed, have a machine shop check to se if there is any warpage that can be corrected by light planing.

I've heard a method to check for leaking head gaskets or possible leaking head is to remove the plugs, spin engine and check for warer out of plug holes. If no water, does that confirm heads and gaskets are ok?

John38coupe, that method would confirm a leak into the combustion chamber. The lack of water being expelled would not confirm that there is no leak, as the leak could be too small to show up with this test or it couls only leak when a certain temperature has been reached. A better test of coolant in the combustion chamber is white smoke coming out of the tailpipe, but it will not detect all leaks either. Tom

If you have a water leak into a cylinder, it is almost certain that you will experience "hydro lock". This occurs when enough water accumulates to prevent the piston from reaching the top of the stroke. At our shop we provide service to a large marina on a nearby lake. When we get an outdrive engine that refuses to turn over, we commonly find a "wet cylinder". If the owner is lucky, they didn't try to put jumper on the battery which can destroy the engine. If you find water, pull the head on that side before doing anything else.
