One thing I just remembered about leak testing those B tractors,you need to either jack up the rear,or remove the front wheels so the front of the engine faces downhill.If a pushrod tube is leaking and the engine is sitting in it's natural position the water will run back inside,and you won't see it until it runs out the bottom.If you used copper washers instead of lead under the headbolts you can pretty much count on a leak.Poor quality ideas and replacement parts are not just on Model A Fords.I was the two cylinder man at the JD dealer in the late 70's,and these problems are floating to the top in my head now.Hot tanking the head will make the copper tubes leak,but the new replacement brass ones are EXTREMELY prone to cracking on installation.
