2u with older 8r motor stuck

The last resort......tear down😊 😊
Probably wouldn't run well for long even if you did get it loose.
You might try some of that funny smelling stuff....Kroil, phosphoric acid, or the secret blend of 50% acetone and ATF. The wine works...but not on the engine😄 😄

I have a d2 that was froze. I pulled it around for about 20 min was perty discouraged went home and slept on the problem. I tried pulling it backwards and sure enuf it come out put it in a forward gear so it turnes the motor the other way and give it a shot. I also used about a gal of krol oil to i poured it in every where you could think.

I use two 20 ton bottle jacks and a couple of chains. Stuck a 4x4 in the sleeve on top of the pistons. Put the jacks on top of 4x4. Hook the chains to something solid on the left side run the chains of top of jacks and hook to something solid on right side. I made a bracket to fit over jack so chain did not slip off with a piece of pipe and channel iron. Make sure the pistons are going the same direction 1&6 2&5 3&4. Put some pressure and penetrating oil on them. If the don't move let them sit over night.
