Super C engine problem

montidale · May 14, 2011

I have a super C that has anti freeze in the oil. I pulled the oil pan and pressure tested it last year and couldnt see any coolant leaking. So I replaced the head gasket and ran it alittle this spring. When I changed the oil I found more coolant in the oil. Does anybody know where they are prone to leaking? I think I am going to put some bars leak in it and run it for now. Any suggestions? I have a woods belly mower on this tractor.
Thanks, Dale

Usually what coolant in the oil means, is a cracked head, a bad head gasket, or a cracked engine block.

O-rings on the sleeves, head gasket, cracked head, cracked block. Less likely, cracked/broken sleeve. If you pressure tested it with the pan off, that eliminates O-rings and sleeves. When you pressure tested it was the block warm or cold? If you replaced the head gasket AND torqued it correctly, that eliminates that.

cracked block or head is the next stop.

Drop the oil pan and see if coolant is dripping from the sleeve seals. Hal

If you drop the pan and let it set for a day or so you will see drops at the bottom of one or more sleeves this means the rubber o-rings are letting coolant by. If you want to wait until mowing season is over you can drain the coolant and replace with 10wt oil so leaking antifreeze in the pan wont ba a problem.

Same thing on my 54 super c. Third cylinder was leaking so i just decided to spend the money and tear it apart and rebuild the engine.
