I got the block skimmed again myself when I re built it so I wouldnt do it again. I told mick that the piston liner had cracked on me but I only got one replaced, so my guess was another liner had gave up cos it was just as old and weak as the first one. I was gonna put a block in it to be safe. If Karl wants one I can get him a standard 205 Cosworth block from a mate.
