In the process of a doing a complete rebuild of my Farmall Super A.
Before rebuild of the engine I was getting water into the oil pan. Took
head in had new valve guides, valves ground, resurfaced and magna
fluxed.
New sleeves in engine and turned crank, new pistons and so forth.
After sleeves installed and without head and no radiator I plugged
lower radiator drain and filled engine with water to look for leaks.
This was about a 30 minute look. There was no obvious leaking.
Put engine together with new head gasket. Installed radiator and
filled with antifreeze. Let it sit overnight and in the morning the
radiator was down about 1/2 inch in the neck of the radiator. Thought
maybe there had been a air burp come up. Note tractor has not been
turned over or run yet. Refilled radiator and after a week the radiator
is down another 1/2 inch. Pull the pan and there is antifreeze in the
oil pan
So looking inside the bottom half of the engine I cannot see anything
obvious partly because leak is so slow.
Yes I did clean groove where sleeve O ring sits
Has anyone ever pressurized radiator with 10-15 pounds of air
pressure to look for leak?
I assume the only place for leaks are around bottom of sleeves, thru
head gasket or a crack in block somewhere.
Is there and hope when the engine heats up and things start moving
that it might seal itself?
Should I consider putting some radiator seal in.
This tractor has no water pump just thermo syphoning
