panzerjager bren project

[Lynn Eades]

Personally I wouldn't try to fix one that has a crack from the cyl. bore to a valve seat. It would basically be a time bomb. You would never know when the stitching would let go, and next thing water is no longer where it's supposed to be.
I am sure guys will now tune in and say they fixed theirs way back in 1763 B.C. and it's still running like a clock, but that's me. I'd want mine to be reliable, so I'd start with a better block and not waste dough on the cracked one. Just an opinion from this ole mechanic.
I wish you better luck with the second one Leo.
