I've got a big custom order in with Mahle to make a run of 87.25 and 87.5mm 11.5CR pistons for all the stock rebuilds going on. I for one am getting tired of only having 1 rebuild on every block. Blocks are getting way to hard to find these days.

I don't know if this block had previously been rebuilt, and I honestly do not know the entire history of the donor vehicle. Which has always been a point of concern for me.
Has there been anything that can prevent the extra oil consumption outside of honing to the next size? Should I recommend to the shop to use a set of larger pistons? Would it be reasonable to go through the original block that I had purchased from BMW even though it went through nearly the same failure that the original block had? (Just probing for constructive criticism).
