High pressure fuel pump shelled

Head over to Rawze.com. many threads on the procedure, and yes, they are cutting corners. If the motor is salvageable, you need to flush with motor oil, and flush, and flush and flush. Multiple filters will be needed too. Same with the fuel system, it is an all day job and not a guarantee that the motor will survive. It sounds like you have a boat anchor on your hands.

To all that own a Cummins ISX CM-2250, 2350 or the new X motor. The fuel pumps need to be rebuilt every 300,000 miles or less. They fail, and when they fail, they take out the motor. There are two style pumps, a three cylinder (the old one) and the newer two cylinder. Originally it was the ceramic plungers in the pump that were failing and taking out the motor. The new steel plungers and tappets are also failing and taking out the motor. The rebuild kits are $400 to $500, a new pump will run around $3,600.00.

Look up Haggai Automotive, he is in Griffin GA. He has much experience saving these motors,

 

Wow! I din't know that he was doing that. I guess just wait on Terry to send an invitation code. Meanwhile, I would call Mr Haggai in the morning and see if he has a few minutes to spend with you. Honestly, from what you described, that motor is in rough shape. As far as an actual Cummins procedure, it normally consists of a new crate motor. The issue is getting all of the shavings filtered out, which is a nightmare as they hang up everywhere in the block and head. I cannot believe they are passing on the cams if the crank is being replaced. How about the liners and pistons? I can only imagine what those look like. Call Haggai in the morning, he is the one that came up with the procedure regarding these motors.

 

I would be in that shop going all over that motor. I would want to see the cams and rollers and get a look at the liners. To me, it sounds like the dealer is not doing you any favors.

 

Here, I pulled this from Rawze.com

As a follow-up to this...

it was the plungers that started to fail, but the rollers that caused all the destruction.

The engine had to be partially disassembled and flushed 9 TIMES ( about 110 - 120 gallons of cheap oil mixed with diesel fuel ) before shavings would stop pouring out of the engine and down into the oil pan. In just that 300 miles, the entire engine was buried in metal shavings. HIS ENGINE HAD the updated plungers and had the updated oil bypass valve. Makes me wonder what the oil filter is even for if so much shavings can get past the pump/filter and into the engine.


Mr. Hag has gotten quite good at saving these engines when they do this if it is caught early enough but even so, he said to me "What a royal Pain in the Arsse. You have to take it all apart down to the main castings (head stays on) and flush/force an oil/diesel mix through all the passages and put it back together, then run it, pull the pan again and look for shavings over and over and over to get it all out if you want to do it right."

They had to replace the pump, do the retrofit to the new style, replace the oil pump, oil cooler, and a few other components like the oil thermostat and oil bypass valve too. His nice new rod and main bearings all had to be replaced too. The shavings had already eaten them up as well.

 

what year is your truck? what engine is it ? cm2250 or cm2350 ?

 

looks like cm2350. where did you get fuel last time? before this failure ?

 

Why is the truck sitting at the dealer, take it to a Cummings repair center and have them don the work. We had a couple tank on us and I trust the Cummings place a lot more than the clowns at the dealer.
