Well boys I finally done it. Let my ole u soak in every snake oil mixture known to man kind and she would not budge at all. So me and my dad tore her down today. Thoes pistons must be really stuck bad. Going to have to drill holes in them and bust them out or try and press them out. But gonna do a over bore anyways. Thinking about pulling her and really putting the EAST TENNESSEE OLIVER boys in their place. What do you guys suggest? As far as heads and overbore limits and all?

Was just wondering if you got the pistons out ever and if you tried the brake fluid and a match?

No it doesnt do any damage to the cylinders and also to get it to ignite better use a little torch to get it to start burning better.

If you are gonna mess with them olivers you better have at least a 5.5 bore and a 7 inch stroke with really good heads and manifolds.

No joke. We did it to the block of a MM JTS. Those pistons were stuck! So we put 1/4" of brake fluid in the cylinders and put a match to them. Brake fluid won't explode, it just slowly burns. We put it outside over night and in the morning it was still warm, and the pistons slid right out. The heat allows the brake fluid to work in around the pistons. It's pretty amazing. Let me know if you try it or not.

Anderson, Would this work with the blocks still on the tractor and then trying to pull the stuck tractor in high gear and break them loose that way?

Never heard of that solution for stuck pistons before! Would the cylinder block suffer any damage? Or is this used just in extreme cases where an overbore will be done afterwards?

If your going to make a puller out of it, throw those blocks and pistons away and get some M5 (or equivalent) 4 5/8 in bore blocks. They will fit right on your U and give you a lot more cubes than just boring the U block.

Now that you have it taken apart. Did you try putting about a 1/4" of brake fluid in the bores and then putting a match to it? It works pretty good.
