Well there are no "O"rings on the sleeves. The tractor has dry sleeves in a cast bore. There are possible head cracks that do not affect combustion chamber leakage. As you noted, a head gasket would also do it. Block cracks in the skirt area of the block are less common. Cracked cylinder bores with a loose sleeve (or pinholes in the sleeve) can also leak. If it were mine, I would put three heaping teaspoonfuls of fine ground black pepper (yes that is what I said) into the radiator, and give it a week of operation to see if I could stop the leak. If not I would pressurize the cooling system to 7psi MAX. and with the pan and valve cover off, I would look for leaks. Step head pistons will work without any concern at all. Best of luck, JimN
