Fordson Major Diesel water in engine oil

Still going strong at least until recently.
I found water in the sump and suspected
(hoped)it may have only been the head gasket.

I've pulled the head and it looks okay.

Does this mean it must be cylinder liner seals
or corrosion round the liners. Is there any think
else that could cause this.

How practical,easy possible is it to replace liners with the engine still in the frame.

It is almost always the sleeves leaking. They can be removed with the engine in frame. Remove the front axle wishbone then the sump (there is a sump bolt up in a groove at the front of the engine near the pully, dont forget to remove it). Also remove the oil pump.

You will need a sleeve puller. I had mine made at the local machine shop. Get a piece of round stock machined 1/2 in thick about 105mm in diam with a 97mm step and a 1in hole. This goes in the bottom of the sleeve. You will need 1in diam threaded rod and a piece of inch thick steel to make a bridge with a 1in hole in it. Be carfull not to hit the crank when you insert the steel rod. With a nut on the bottom abd one on the top, the steel bridge with blocks of wood bridging the cylinders, get a big spanner and a piece of pipe as an extension and pull em out. Be aware they take some shifting. I usualy wrap the crank journal with a rag. I have had to use a six foot pipe as an extension to shift em in the last engine I did but usualy they are not that bad.

You may need to replace the sleces as electrolysis eats em away at the bottom. I would at least also replace the rings and bearings.

Good luck
