    I wanted to ask about a truck I'm looking to buy. The truck has 330k miles and 25k hours. The truck itself is spotless inside and out. It having 25k hours is like having 800k+ miles ? The truck also has a PID 100 code, I did a look up on it and says low oil pressure. Me not being diesel mechanically inclined all that well does the motor need to completely come apart to change oil pump ? I've attached the JPro report of the truck. As I said the truck is extremely clean in and out with new rubber all the way around and everything else works I just don't know if this would be a good buy at 45k as my starter truck.

    25k hours is rebuild territory for an engine. I would count on it needing an overhaul soon.

    inframes are less than full out, but 10 to 25 grand probably is a fair guess to start.

    I lost a camshaft in a 99 Mack R series, that was 6 grand alone. (and that was 6 years ago) Had them test the rods and mains but they were still good.

    If you can figure in the cost of an overhaul, and have the seller's price reflect it, and you have it in your budget I wouldn't hesitate. Mack makes one hell of a tough truck. I spent most of my first summer in a 98 Mack dump truck, and about all it got maintenance wise was it's oil changes. It went to work everyday and made it's owner money and me a paycheck. Actually one of the trucks that I have driven in the past that I actually miss.
