    That's pretty damning against the Cummins and ISX engines.

    Maybe isnt that why there are mountains of those engine slaying around under a tarp because they are actually crappy?

    No wonder everyone is in a exodus to Detroit.

    The Volvos are almost exclusively for the “million mile” drivers. KW wise the older T-680s with ISX mills are replaced by X-15 models. The day cabs have a mix of ISX and Paccar engines. The International ProStars are being phased out,being replaced by LT models with the X-15.
    Almost everyone I know is getting the Cascadia with the Detroit powertrain. My 2017 already has 226K on the odometer,about halfway through the warranty period.So when it comes time to sell this truck, more than likely they’ll either put me in another Cascadia with a Detroit, or they might give me a KW with an X 15. Either way, either truck is going to be an automatic, SMH.

    If you tried to buy a Freightliner Retail made to order today with unlimited money cash with a Detroit engine, you will be told it's approximately 9 months before you physically have that truck sitting on your property pending paperwork, plates, stickers etc.

    The result of this delay is forcing the industry to buy whatever truck is ready today. Whatever it is. In this case it happens to be a majority of Cummins and other engine power. If you were willing to risk a Pre 2000 truck, you did that too.

    Well worse comes to worse, you could always get a Volvo with a D13 engine.You really can’t go wrong with those.

    You must be new. Should of done your homework besides looking at the pretty truck from the outside and the luxuries it offers from the inside. Sorry for your lost investment. This was a common issue Cummins had. Doing some homework would of saved your pocket book. You might have some light at the end of the tunnel so to speak, depends how well you can communicate with your people persons skill. In other words, BS into having Cummins meet you at least half way. Goodluck

    A very well known issue on the Cummins CM-2250 and CM-2350. There was a TSB and a short campaign to fix this issue. Originally the ceramic plungers in the fuel pumps were failing and taking out the motors. They switched to steel plungers thinking that would fix the issue, it did not. Cummins has since canceled any recalls and TSBs on these pumps. The new pumps are running around $3,000.00 + Labor to install. Rebuild kits may still be available... It is recommended that the pumps be rebuilt or replaced every 300,000 to 400,000 miles. A costly affair. The new X15 motor has the fuel pump isolated from the oil circuit.

    But, in your case, if it did what the dealer stated, the motor is scrap.

    Was there no fuel pressure warning code/Check Engine light? It should throw that code, when it does, immediately shut down and tow to a shop, the motor can normally be saved. By saved, it is still a $10,000 to $15,000 affair. Basically a mini in frame and hours upon hours of flushing the metal out of the motor. And there are still no guarantees the metal will be entirely flushed out.

    Is the motor stock, or was there a delete? If no warning light, I'm thinking someone "fixed" this motor.

    As far as the dealer, good luck, unless you are a very good customer he may just let you eat this. Last long block I had looked at was $38,000. You can get away with a short block in this case, problem is you will not have a core. Sorry to hear you were bitten. You did not do your due diligence with this motor, and the dealer you bought it from surely knows of this fuel pump issue. Good luck.

    The campaign on these fuel pumps only lasted a few months. It was on the CM-2250, then Cummins redesigned the fuel pump and went with steel plungers vs the ceramic plungers. The pumps still fail and need to be rebuilt/replaced every 400,000 miles or there about. The new X15, Cummins isolated the oil circuit from contamination when the pump cuts lose. No clue if Cummins will step up, that will depend on the shop/dealer.

    Where are you having the overhaul/in frame done? Be very very cautious as to where you take it. I am on my second in frame in two years, almost to the day. The licensed certified Cummins shop that did the first one installed CM-2350 parts in my CM-871 motor. They also skipped many steps in the assembly. The motor was going to blow apart in another few months due to the shoddy reassembly of the motor. The wrong parts were just the icing on the cake. I did my own in frame (the second) in Rawze's driveway, with his and Mr Haggs help.

    One thing. VERY IMPORTANT! The block must be machined! Do not skip this most important step! Or you will be in framing the motor within 100,000 miles, if not sooner when a liner busts lose. The liner steps MUST be machined!

    If you are not confident in this shop, or have the slightest doubt, call Haggai Automotive and Diesel Repair. He is the premier Cummins rebuilder in the country. He is located around the corner from the Atlanta Motor Speedway in Griffin GA. (678) 688-8107

    I get nothing for referring you, but I did spend quite a bit of time in his shop while waiting for parts and the weather. Jerry (Mr Hagg) rebuilds the motors by the book, and he stands behind his work. If I ever need anything major mechanically done, it is going to his shop if I cannot do. Folks come from all over the country to have him do their in frames.

    Just my .02, as I would not trust anyone to do this job properly. I can see why many shops skip many of the steps in rebuilding, it is a rather tedious affair. The reason I did my own.
