    You’d need to ask Mack on that motor what ‘acceptable’ blow by levels are, but from what I see it looks to be fairly low.

    Congratulations for doing proper pre purchase checks - many don’t.

    They do seem rather low.

    I agree. They almost seem too low for a high mileage engine. I wasn't present when they ran the dyno or I would have asked a lot more questions.

    The Blowby test wasn't done right, it should be up a lot higher, just at idle it should be about 2 inches of water.
