Over the winter I bought a stuck 1030. Before I bought it I pulled the oil pan and found all the crank bearing appeared to be okay. I want to put somesort of oil (trans fluid or kroil) into the cylinders to free it up. What do you think the best way would be. I was going to pull the injectors, but would a guy be able to put it in through the valves in the head? When I had the pan off I could see antifreeze dripping from the outside of one of the sleeves, but I would like to get it free before I tear into it.
 
You are gonna have to replace the sleeve o-rings anyway...might as well pull the heads and see what the problem is. Probably should re-cut the top flange the sleeve sits on when you get it apart. 1030s had a problem there.
 
Daryl: What do you mean "cut the top flange"? Yes, the 830's & 1030's had a problem in that area, exasperated with ether use, but the problem is that the upper flange area will crack. Many engines can be fixed, using a repair, but with the 830's & 1030's, there is no room for a repair. Been there. However, on the 1030 I've been 5 years restoring, I concocted a fix using "stilts" or legs under the flange reaching to the bottom of the water jacket for support.
 
Why is it stuck? Takes a lot to make a diesel sieze, most require taking the heads off. Since you have to pull the heads to fix the o-rings you might as well start there.
 
Years ago I had an A/C XT190 diesel that was stuck due to bad injector pump seals which cause it to have diesel in the oil. I pull the injectors and fill the cylinders with turpentine. I let it sit a few days that way with the injectors sitting in the holes but not tighten down. I then set a battery in it and tried to turn it over. After hitting the starter a few time with the switch it spun over and I went looking for a couple of injectors since it threw them a good 40 feet
 
Jon, the previous owner ran it with water in the oil, everything looks good on the lower end of the engine so I suspect it's the pistons that are froze. I read back into the archives about having the front end off the ground on one of these trying to get the piston out, may have been one of your posts. I just thought it would be easier to attempt to free it, before I get into it.
 
That may have been mine as I did that, never got them out. But water in the oil would damage the crank and maybe cam, but not the pistons. You can usually pop the piston/sleeve assy out as a unit. Mine were hard because it has sat so long the pistons had corroded in the sleeves expanding the sleeves and pinching them in the block. I had to break 2 of the pistons apart to get them out. But it has sat with water in it from a bad head for a decade or more.
 
If you are in love with it, it might be easiest/best to find a 1070 engine to drop in it.

It will be money pit to fix the original engine.
