A new head gasket isn't all that costly.

That tractor is selling really high here in Michigan. Ones needing overhauls are still selling in the $2000.00 range.

City people living in the country like them because they fit in their low grarages and look cool to all their

city friends that visit.
You might want to ask these people about the oil in the water. These people love their little fords, no there is nothing wrong with them just over priced here for the years on them.
