Hello, I recently received a Ferguson TO-30 in a deal with my uncle. It is a 1952 model and it has a Continental z129 engine. My uncle had a hose break on it last summer and replaced the anti-freeze with water,using it all summer. In the fall he he replaced some of the water in the radiator, turning the motor over but it never started. This spring he started it but he noticed it had no oil pressure and immediately shut it down. Today I checked the oil and it has water in it. I need some advice. Is this tractor motor shot? Is it possible that only the head gasket ruined or is it more possible that the block is cracked? I have worked on engines before and I think I could replace a head gasket. A complete rebuild is above my ability. I hate to give up on this tractor as it has been in the family a long time. How should I start? Any Ideas?Thanks Jim Bob
