But i agree 1 or 2 busted blocks is cause for concern.
We know of 3 reported instances and one that happened at the shop. Brand new EJ25 case, built internals, poof magically the cylinder wall popped at like 23psi or something around that area.

Not taking the chance... I am ordering my cosworth short block next week ^____^ the shop told me that cosworth stands being its products so if anything does happen I'll be good in that retrospect.

I am surprised there hasn't been a whole lot posted on this issue. I guess its just now becoming more publicized :/

Someone told me to sleeve it but I said for less I can get a cos block and save money to build the heads later... I think overall its a win situation to avoid the headache down the road
