I recently purchased an international 434 that was running poorly until it was parked for the past 2 years. Had to pull start it, and it was leaking oil from engine housing, dipstick tube. Oil was cloudy grey. Lubricated rings thinking they were likely stuck. Sent a can of blue devil to repair head gasket. Changed oil. After leaving it for 24 hours and running again for an hour, it lost a good amount of coolant. Oil on the dipstick was 1/2 quart low but it didn’t look like it gained any additional coolant. It was slightly milky, but there was lots of lousy oil still remaining on the sidewalls of the oil reservoir. And level didn’t go up at all. So I think the coolant no longer is entering the oil reservoir, but blowby is still leaking out of the engine housing which is still very grey. Trying to avoid a full tear down until I know it needs to be done. My questions are as follows. If the head gasket is good but cylinder head or block is cracked, would this explain lost coolant that isn’t entering the oil reservoir? And would buggered rings be the most likely culprit for excessive blowby, or damaged cylinders/walls be more likely?

While I love straightening sheet metal, cleaning, and painting old tractors, I use every excuse to avoid working on the on the electrics. I find the whole process sheer mystery. I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
