Cummins complete failure just after truck purchase.

I would check to see that engine has extended warranty . I am talking about 500k extended warranty. I know cases when freightliner has changed the engine due this kind of failure. Go to Volvo dealer and check to see that truck has extended warranty or not.

 

I have seen this engine fail in this manner even after the plunger and tappet up fit and the oil bypass valve update. Sometimes the damage is already done and takes a while to show up later.

Put in a new running complete engine with a warranty and get back to work. Sort it out later. The truck will be down 3 times as long if you wait to sort through the politics. Just what I would do.

If you are a second or third owner with no factory warranty it is unlikely you will get help from Cummins, but you may get help from the dealer you bought it from, depends.........

 

We have a CM2250 ISX in the shop right now due to the same fuel pump failure. It’s not metal, it’s ceramic material from the pistons in the transfer pump. Anything in the engine with a pressure fed bearing will be destroyed. You don’t even have a rebuildable core at this point. Find an engine, lots of used ISX’s around.

 

Cummins out to be sued in a class action.
@Daffs26 you need to talk to @Justrucking2 he can tear his own isx apart and out iy back together. He may give a reputable shop out near California. The isx is very particular engine design, with some very bad parts that fail way to easily.

 

Cummins has had nothing but issues with its ISX engines.Between the EGR valve issues,the turbos failing and the cylinder liners getting scored The engines are quickly becoming glorified boat anchors!

 

I'm done with online know it all diesel mechanics .
Having mine overhauled and updated .

 

Considering there are more cummins in trucks than any other engine, it makes sense that they would have more defects.

I'm not making excuses for cummins.

 

I didn't pay much for the truck and expected to overhaul it to begin with by 700k .
Is what is. ...rest of the truck is stellar .

 

We used to have a lot of Freightliner Cascadias with the Cummins engines but most of them have been retired and replaced by Detroit powered trucks now. The KW and some of the Volvos are still Cummins powered though(mix of ISX and X15 power units).

 

How much of that is choice and how much availability? I hear the 1 - 2 punch freightliner/dd is pretty hard to come by right now(new.)
