    It all depends on the kind of job, that the customer wants. Cat says that.005" and more, should be repaired. All of my expert mechanic customers, follow that recommended spec. I install many, many of them, each month. I do not require them to follow that spec. It is up to the mechanic.

    My 6TS had the issue back in 04 found during overhaul. I had them deck the block. Cost an extra 5 grand plus everything they replace while engine is out.

    I believe it comes from poor coolant maintenance.

    All mine were pitted on mine. Block deck grind brought everything into spec.

    This is a way of fixing the deck, in frame. Saves much money.

    Couldn't disagree with you more. This guy seems to have come up with some fixes for unfixable blocks. I don't remember if it was cummins or the Paccar that didn't have a fix more sunk liners but I believe this guy came up with a fix.

    And as these cat blocks keep getting older you are going to see more repairs needed to water jacket holes. I know when I overhauled mine they were looking a little rough but not bad enough to need fixed yet. And yeah I'd rather buy this guy a plane ticket to fix in the truck than to have to pull the engine out
