Water leak into oil pan Farmall Super A

Mtjohnso · Apr 4, 2019

I have a water leak into the oil pan on my Farmall Super A. This model does not have the water pump.
The engine is now on the shop floor. Head has been rebuilt and magnafluxed in the process.
The head gasket did not show any leaks. The sleeves do not show any issues that is apparent to the eye.
So how to best determine where the leak was?
I was planning on replacing sleeves since it is a wet sleeve.
Thoughts, suggestions?

Most likely a O ring on the sleeves leaking. It looks like you have every other possible leak points covered. A cracked sleeve sometimes is hard to see though. They can crack close to the top of the ring groove if sleeves were put in without clearing the bottom bore properly.

You should have dropped the oil pan, crawled underneath and looked up before draining coolant and pulling engine, IMHO.
