I gave up on finding my machinist with mucho MB experience. I guess he's gone to Disneyland. He's a one man shop and his phone has been ringing off the hook for a week and a half. I hope he's okay.

I know a reputable machine shop that can do the machine work competently, but I was looking to the other machinist for advice regarding replacing the liners or simply going to the next overbore. I would not reuse the pistons in either case.

Is there any valid reason to go the extra expense and replace the liners rather than over bore. The oversize is .5 millimeters, which I believe is only .020".

Any experiences in this area that you can share?

Thanks everyone,
