1066????

So I'm working on our 1066! This fall it was pressuring the radiator wouldn't get hot just build pressure when worked on the harder side and blow water out the cap! And when on the blower this year she blew the seal behind the damper pulley! So fixed the seal and put new brass cups in got it running again had a slight rattle in the top end! Which I thought it earlier this year but with the hoods off you could really hear it! So adjusted the valves still slightly rattling! Took the head off guides shot had the head all redone at a machine shop! So then decide might as well do the torque so took the torque houseing out getting new ta installed! So after a month of me and dad arguing about spending more money he finally decided to go along with my idea of just putting a in frame over haul kit in since tge tractor is all apart and has over 9000 hours on the original engine! So tonight I went and pulled the oil plug to drain oil to pull the pan! And a couple pints of antifreeze came out! Now I'm wondering were that came from! Wondering if thiers a cracked sleeve or if my brass cups in the injectors would have leaked but if it was them it would have antifreeze on the top of the pistons when I removed the head and thier wasn't so I'm thinking it could be a sleeve! Any ideas oil cooler posible?

Real common one of the o rings around the lower part of the sleeves probably . Now if you are going that far go on and pull the oil cooler there on the side and pressure check it. If you do not know how drop me an e mail and I can tell you a fairly easy way to check it.

The pressurization of radiator was probably due to cavitation pin hole in the sleeve. They are hard to find when looking for them in the sleeve unless a big one. Do take off the oil cooler if for no other reason than to clean it out as they can hold a lot of crappy oil. If you find any bearing or piston contamination in the engine it will hang up in the cooler also as it is before the filters. I would check the camshaft for lift and condition of the lifters. I know, where do you stop but cam failures are common. When you get new sleeves and pistons, you will have a choice of wide gap rings with pressure balanced pistons or regular. The wide gap will give you much better oil control but you need valve cover breather to go with them. Then it would be prudent to install the latest type of rocker arm supports for proper oiling of the camshaft. This is why the repair bills often exceed initial expectations.
