767Jockey,

I've been watching your progress with resolving the porosity problem. A block that has porosity problems in the cylinder walls has porosity problems elsewhere also. Elsewhere can easily be the main webs. Last thing you need is to start cracking and/or pulling main webs out of the block.

The block they sent you is basically scrap metal. If it gets sleeved and resold the new owner runs a high probable risk of structural failure elsewhere in the block because of the same porosity. When the failure finally occurs there will be yet more posturing about whose at fault for the failure.

There is no guarantee that they either understand the reason for the porosity or know how to fix it. Imagine getting a replacement block only to suffer the same porosity problems but in a less obvious location - and probably similar or worse delays in getting a replacement. Sadly, the replacement for the second block will probably be as bad as either of the first two.

I think you might want to consider a value for value exchange. A refund of your monies for a return of their block and then use a different manufacturer.

Wish you the best in securing a fair and proper resolution.
