VAI crack in block

What can we do? Is this a common thing for the VA series? Anyone have any ideas?

I use lacing plugs and have for many years,

but the deck between the cyl's is not a good use

for them . A bolt thru the water sys into the

pushrod wall and sealed , will pull the block

back together and help to prevent another crack.

Then grind out and weld the crack , plane the

deck , recut the pilot bore and the counterbore.

I fix the Z and J series continental engines that

way and have for years .

Lacing tend to push the crack in the deck wider

apart and does not give any support to the cyl

liner and with out support under the liner you

lose the crush on the head gasket making gasket

failure almost a sure thing.

Also see the webbing sink between the liners in

the 4020 JD engines causing gasket trouble, they

sink .003 to .004 , plane the deck about .007 and

problem goes away and they start better.
