My 801B is getting antifreeze in the oil pan. I removed the heads and refilled the block with antifreeze. I came back a week later and there were two cups of antifreeze in the pail I had under the pan (plug removed). I've sent one of the heads to have it pressure tested as it had a lot of funky oil in it when we took it off. I then removed the pan to look at the bottom end. There is a slight amount of antifreeze on almost everything. There is antifreeze all around the bottom on the cylinder sleeves. There is no obvious leak point.

My questions are: Has anyone had or knows of a cracking problem with this block? Has anyone had or knows of a problem with the wet sleeve o-rings failing? Does anyone have any tips for trouble shooting this problem? Is there anything specific to look for?

My next step is to pull one of the sleeves to check the o-rings.

Thanks,

It is either your o-rings or the sleeves are not seated properly. Before you reinstall the sleeves, I suggest putting them in the freezer overnight. This makes the metal contract enough for installation to be easier. Unless you have done this before, take it to a good machine shop and let them do it.

If you had the block level and full of antifreeze and it leaked down evenly, you most likely have a bad Oring at the bottom of a cylinder, if there is no water inside of the cylinders, Some of these Case tractors were noted for cracking sleeves just below the top of the block. At any rate you need to take out the pistons and check the sleeves for cracks, Then replace the O-rings at the bottom of the sleeves. Since these are wet sleeves you can use a puller to pull them or drive them out with a piece of wood. You do not need to freeze wet sleeves if you have everything clean and grease the o-rings.
