when i got the la and ran it home it ran hot- so i looked in the rad. and it had a lot of rust in it-- took it out and cleaned it good and proper--put it back in -painted the thing up real nice-new tires ect.now it was time for a ride--the farther i went the hotter it got -till it steamed--felt the rad. and the only hot part was the top--i shut it off--the the water started to move on its own- restarted it and it cooled off-- took it for another spin --same thing-is the head cracked? head gasket out?the water seems to circulate until it starts to over heat! any case experts got any ideas on whats going on???
 
Roy, those LA Case heads sometimes crack. The crack often does not go through to the water jacket and does not present a problem. In your case the crack seems to be reaching to the water when the pressure is on. The next step is to pull the cylinder head off. That head is a heavy chunk of iron. When everything is loose and off, pull the front plug and put a 2x4 and a bottle jack against that part of the head. Then use a large steel bar in the rear exhaust port with a 4x4 and jack, push up. Then get a 40 ton crane to lift it off. Have your local machine shop check it out. Have fun and enjoy your Case LA. -- Derrol in Texas
