Ford 7710 motor

I have a Ford 7710 that I know is in need of a head gasket
because it is getting water in the oil. I know the head gasket is
part of the problem. My question is. What are my options if the
block turns out to be porous. This is the 1st series with the q
cab. Thanks for the help.
 
I can almost guarantee you that the head gasket is NOT the problem, and I can give you almost an equal assurance that a pinholed block is. Don't waste your time pulling the head. Drop the pan and then pressurize the cooling system to see which cylinder has the hole in it.

Once you confirm the hole, remove the engine, strip it down to a bare block, and get it sleeved. It won't be cheap, but it's pretty much your only option short of finding another engine.
 
Well the only reason I said the head gasket is because I can see coolant running out of it at the back of the head. I wasn?t sure if those engines could be sleeved or not which is kind of what I was looking for. They are sleeveless from the factory right?
 
It's fairly typical of those head gaskets to leak a little coolant down the side of the block, but that fact has absolutely zero to do with the water in the oil.

Correct, they are not sleeved from the factory (this is called "parent bore"), and yes, they can be sleeved at a machine shop. Suggest your machine shop bore the block for thick wall sleeves and then re-bore to size. This is a little more expensive than conventional pre-sized thin wall sleeves, but it ends up doing a better job.
 
Ok thank you very much for the help. I had intentions of building the motor and figured that I was gonna run into this problem as much as I didn?t want to and wanted to have an idea of what to do. Thanks again
