In this torque sequence, the Auxiliary bolts are only torqued to 22 ft-lb. This seems like a very loose specification. I would think at least 40 ft-lb. These are the smaller bolt numbered 5,6 and 7. When I was removing the head they came off with extremely little effort. They were tightened to the spec. given.

Would anyone care to comment on this observation please?

My engine was blowing compression gas into the cooling system which lead to overheating and smeared aluminum pistons.

Those tractors, I believe, were Yanmar engines. On a lot of those they used crank pulleys that were "Clutches", meaning they had friction material when engaged. The material wears out over time, so your cooling fan doesn't spin as fast as it should to move air through the radiator. Something to check and keep an eye on, but what I see in your video, I feel you have exhaust gasses going into your coolant from a blown head gasket. You can buy a tester, easy to use, to verify.
What is that kind of tester called?

I'm very grateful to all of you for helping me. We were able to get the tractor running well today.



Thank you for filling in the many gaps in my knowledge.
