Well, I tore into our 1940 Farmall M today. It had 60 psi on cylinder 3 and 80 on the remaining cylinders. The head gasket was blown out between 3 and 4. The problem is that cylinder 3 also has at least 3 or 4 sets of corrosion grooves where the piston had been sitting in one spot for a long time with the valves open. It also appears to show evidence of discoloration of the metal, but it could also be rust damage. 2 and 4 have less pronounced grooves as well. Three of 4 pistons are covered with a blanket of prickly black carbon (burning oil?). The grooves on cylinder 3 are deep and easily catch your fingernail. All 4 bores have no remnants of the crosshatching on the cylinder sleeves. Additionally, I can wiggle the pistons in the bore at least 1/16 inch if not more. I was wondering about the following: 1) Does the above sound like grounds for a rebuild? (just want to make sure I am not being overly fussy; I don't want to part with more money than I need to) It is a work tractor, so it needs to be dependable.
2)It has 4 inch thin wall sleeves with what appear to be original aluminum IH firecraters installed under a 6336-DD Kerosene head. Can I still get a set like this (along with all of the gaskets, pre-overbored 4" I.D. sleeves, mains etc. for an inframe, where is the best place to get them, and what will the damage (to my wallet) be? 3)Is there anything I should know or check to make sure I don't rebuild it and wreck new parts? 4)It overheated idling for 15 minutes on a 70 deg day in neutral last year, which triggered the head gasket failure. I since found out that there was not thermostat installed, so it definitely wasn't the problem. The radiator and hoses are all new and the water pump belt was new and properly tensioned. It has no coolant ending up in where it doesn't belong, so I am wondering if anyone has an idea what would have caused such a severe overheat. Only thing that springs to mind is water pump. I just don't want to repeat this incident again in a year.

Today's Featured Article - Talk of the Town: How to Remove a Broken Bolt - by Staff. Another neat discussion from the Tractor Talk Discussion Forum. The discussion started out with the following post: "I have an aluminum steering gear housing with a bolt broken off in it. The bolt is about a 3/8" x 1 1/2" bolt. I've already drilled the center of the bolt out with about 7/64" drill bit the entire length of the bolt. Only one end of the bolt is visible. I tried to use an easy out but it wasn't budging and I didn't want t
