I purchased a 1948 B that was stuck. I took it apart to find the block had a crack in it that was un repairable.
I bought a reconditioned block from sharps tractor that had been bored and sleeved (std bore) with new pistons. When I got the block I took it in to Arnold motor to have it surfaced.
I also had them totally go through the head. New valves, springs, pressure test. everything. I also had it surfaced.
When I put it back together I used a new head gasket with we copper washers. After getting it all back together and torqued at 96lbs I had it running good. A few days later I opened the petcock to start it and water ran out of both cylinders. This happened every time I would open the cocks.
I took it back apart and took the block to a different Arnold motor supply to have it pressure tested. Sure enough water was leaking in around both petcock holes and one spark plug hole. (Where the sleeve meets the block.)
Frustrated I got another block that had never been cracked. Had it bored, sleeved and surfaced.
Put it all back together with new a head gasket, washers, etc. At that time it did NOT leak. Got it out 3 days in a row to run it. NO LEAKS!! Now after putting some hours on it I am getting water in the #2 cylinder again. Grrr
I ordered a new John Deere petcock put it in and it is still leaking out around where the sleeve meets up with block around petcock hole.
Has anyone else had this problem!!??
Sorry about the long post but the thought of tearing it all down for the third time about makes me sick!
P.S. I also forgot to mention after it has been running and it is hot it doesn't start leaking again until it cools down. Maybe it is expanding and sealing up while it is hot? Then shrinks back down and starts leaking when it cools off??
Thanks in advance for your help!
