I got the engine loose, it has a bad head gasket (4000+ hrs) and all the pistons and sleeves are pitted. #s 2 and 4 Had antifreeze in them.
When we were turning it over to loosen things up some, it would lock up about every six revs when #s 1&4 were at BDC and 2&3 at TDC. After setting for a little while it would loosen back up. At one time my brother got 64 revs before he wore out and I put in about 20 and it locked back up. After that it would lock at random places.
The Only thing I could think up is a bearing problem. It cant be the trans or hyds.
Sorry about the ter
