The stuff I used to seal the block has worked . I did not have time to re do the sealing process prior to heading off on a rod run last weekend. As the leak was small I was not too concerned about water loss but took some with me just in case. Anyway the round trip was approxomately 650k and there is no sign of any coolant on the garage floor after 5 days. This stuff must have been doing its thing in the crack after it was flushed out.

Hang loose and enjoy the ride.

LON, do you get that anywhere in particular. The last stuff I tried did not work. Spoke to the people who distribute it in Sydney and they said leave it in longer.

Hang loose and enjoy the ride.

56 effie ,

Another product is Chemi-weld . It will seal just about any size hole .A few years ago when I was driving company trucks ,a big hole appeared in the side of a Cummins diesel I was driving . Took it to the workshop ,added 2 bottles of Chemi-weld and ran  it at full throttle for about 30 minutes  ,no more leaks .

That's exactly the procedure for the K&W sealer we have.  Works magic, but won't work with anti-freeze.  That's why you flush.  After it cures, anti-freeze won't affect it.

I have just been down to the local auto shop an picked up a product called CarGo metallic seal up. Have to drain & flush the system add the magic potion and run it at temp for half hour or until leak stops.Not sure how it will go as it leaks only when cold, however it could be evaporating when hot. About to go and give it a go.

The next step is to search for a sealer and it appears that the leak is small enough to keep cruising so thats the good side. The next question is to go a pour in the wet side or stick it to the outside.

Don't throw out the other block just "cause it's .060" over, you should be able to find +.080" for a 292 ,or you can use 312 pistons +.030" = +.080" 292 (312s have the same pin hight as 292s)  most 292 blocks can easily go 3.880" and then some. Might be a good idea to check the thickness of the cylinders though.

Although the Windsor is a Ford, it would be nice to see you keep the "Y"

Here in the states we have available "K&W Block Sealer".  Very good product, use according to their instructions, and it will seal your porous block.  As a teenager, I put some in a 6 cylinder chev that had frozen and cracked the block the full length.  Water ran out in a stream the size of a pencil.  Put the block sealer in and ran the engine, adding water as needed to keep it from overheating. The stream slowly reduced in size until it quit leaking, and the side of the block dried off.  Never leaked a drop afterward.  Maybe you can get it or a similar product in your area.  They claim it will stop leaks into the combustion chamber from a cracked head also.

Well the leak is back and has taken quite some time to find. It only leaks when cold and may not show signs for 3 or 4 days. I had to pressurise the cooling system and found that I have a porous block. It is coming thru just behind the oil filter below the oil pressure transducer. Looks like I am up for a new engine. The block I have in the shed is 60thou over and in very poor condition (rusty bores). It looks like it will be ok for the cruising season and I will have to look out for a replacement but the prices of rebuilders is making me think a 351 windsor would be best.

Well I eventually got around to removing the inlet manifold and sure enough there was no sealer on the front studs, I was also finding the valley cover to be wet. Took it for a couple of good runs and as yet there is no water on the garage floor so it looks like that was the problem.
