Pierre, my O had the same Welch plug issue, at the back of the motor, it's just above the bell housing, you can either cut a hole in the fire wall or as I was advised by more experienced practitioners here, knock the old plug inwards then fit a new one on top. Second method was the choice. And like Morris said, I had to do all the others first. A lovely old truck with a nice purr as long as 38 mph is your speed.
I would strongly disagree with your “ more experienced practitioners “ re knocking the old Welch plug in. All you are doing is creating a blockage (overheating) and more metal to rust and block the radiator tubes.
Thanks again guys for your responses appreciate the input from all.
PDU, sorry to see your engine in such a state, that looks nasty.
When I drained the sump on my spare truck I got 4 litres of water & 2 litres of oil, no wonder it wouldn't turn! Junked it.
Wish you good luck in the hunt for another motor.
Some photos as promised. Hope they upload OK.
I could have sworn I read somewhere there is a welch plug at the back of the K Model block under the clutch housing!
I just checked & there is one at the back of the head about 1" diameter, but it does not appear to have been leaking.
The only reason I was heading down this path was I found water sitting in the Clutch Housing Bottom Cover when I removed it!
So how would water get in there?
A quick check of the manual & it looks like your right overnite, it doesn't show a welch plug at the back of the block.
Sorry to reply with more questions.

OK, this is where I saw the reference to the core plug under the bell housing. Came from an article in the HMVF Military Forum in the UK in response to a query from a member with a 1940 Bedford MW 28HP.

The core plug is under the bell housing between the mated surfaces".
Can someone who has taken a K apart please confirm if this is correct.
I could always drop out the connecting rod and push rods to number six and run it as a 178 cubic inch five cylinder!?
I don't know how long this engine was sitting but interestingly when pulling it out I was amazed by what I found inside the clutch housing when I dropped the lower cover . . .
. . . and that was taken directly after it came off, full of dirt, and a small wasps nest BUT no water
Who bob tailed the rear of the chassis?
Had a customers Ford tractor leaking water out of the bell housing. No worries says I, welch plug at the rear of the engine, which you can see is leaking. Trouble is the bottom 8mm of the plug is covered by the top of the bell housing, so tractor has to be split to fix it. Not really a big deal. Get the tractor into the workshop, off with the front end loader . Split it in half and replace the plug. Time for lunch.
Re-assemble the tractor and refit the loader. Fill it with water and start it up. Whoops, leaking out of the bell housing. New plug is fine. Tear it apart again to find there is another plug behind the flywheel. Should have looked harder in the first place. Hard to charge double labour for your own stupidity.
Bloke up the road has a Hough IH 4x4 loader with a rod through the block..... bit of weld on the oil hole ,broken rod wired to the starter,hole plugged with rag and silastic....been running for years like that .......I gave him some Neuess pistons and rods,doubt hes ever kept them.
Damn, you never know, I'm tempted to do it just for the sheer hell of it
And I do have a spare Humber engine and gearbox sitting in the shed. Good enough for a Commer and 4.2 litres against the Bedford's 3.5
