Hello All- Last year, I found engine oil quantity rising, while coolant level was down. The service manual says 'replace oil cooler". I did this, and drained engine oil, changed oil filter, and purged crankcase with butyl celosolve. Drained crankcase, changed oil filter, filled with fresh oil. Cranked the old girl up, and ran over 18 hours on the clock doing odd jobs on the farm. I noticed low power going up a grade with the bucket full, but not very low. The next morning, engine would not start until I advanced the throttle a little past normal. In an hour of running, I noticed low power under load again. Parked the tractor pending further investigation. Upon parking, all fluid levels were normal. Several days later, the engine would not start at any throttle setting. Fluid levels still normal. Several weeks later, I determined to trouble shoot the problem. The fluid check showed 2 gallons down in the radiator, and 2 gallons overfull in the crankcase. I don't see how that much coolant could leak through a head gasket not under pressure. The book says bad gasket, cracked head, or cracked block. I need some ideas/insights into what the problem might be, before I go pulling the head off. The low power thing has me scratching my head, but it must have some bearing on the situation. I appreciate any and all ideas. Regards, Clark
