Dave,?
Metal shaper, yes, I think he would use the Locknstich technology to work on my original block.? If he were close by, I'd have gone there first.? The machine shop I'm using locally, uses Locknstich, indeed they are using it on the replacement block.? Their
judgment is that the "vertical" cracks are not well suited for it. Another option is to get the engine to the? Locknstich facility in central California and have them do it.? I'm guessing/hoping that the replacement block is a better candidate.? I'm not recycling
the existing block, maybe someone else can use it.
Another factor here -the valve seats.? i? have a vague memory, from the 1970's- when the engine was overhauled - the machine shop had trouble getting the valve seats in.? The shop doing the work now says these seats are uncommonly wide.? It appears to me that
the installation of these seats, however they were fitted, may have caused the cracking.
Metal shaper's discussion of how to make the rear seal work is what motivated me to get into this in the first place.?

On Behalf Of Dan Mulholland ? Continuing on the story, the engine from the wagon went to the machine shop for an evaluation.? They didn't like this condition: ? ? What we have are genuine block cracks, cylinders 2 and 3, that go from about an inch on the top, under the valve seat, and down the inside of the valve "hole", not sure of the proper name.? While Locknstich makes products and has a process for dealing with cracks, the depth down the valve hole they didn't like. ? So, the search began for a replacement block.? Nothing on Craigslist, anywhere within 1000 miles.? 150 miles to the south were a pair of engines that were complete, that had been used for a school project years ago, then stored.? Engine #1 looked like this: ? ? ? No pistons, or pushrod's; surface cylinder rust, one crack, but smaller, and does not extend below valve seat. But never bored out. ? Decided to look at engine #2: ? ? Notice the crack across the top, including under the peened area, and from the exhaust valve.? I took this engine back.? ? There turned out to be a third block, with no head.? It looked great on the top, no cracks, never bored, hooray! Until a side view revealed... ? ? A little patch and JB weld, maybe? ? This engine does have a good crankshaft,? helpful connecting rods, and a decent camshaft.?? So, we're going with the first block, with some parts, probably, from the third block.? ?
