Engine decking issue(help)

That's not the machines fault. That's a piss poor machinist. You say your measurements show one engine is .005 off and the other is .006 off? The dude should have been fired and sent to work at a fast food drive through.

YR, I think they did send him to my local McDonalds, judging by my last quarter pounder with the cheese hanging half off! Next time have him sent to your own local fast food joint, NOT mine.
