Paccar vs Cummins

Stick with a Cummins pre 2010 isx 15 871 model, anything after on the isx will give up trouble on fuel pump,,, enough of a problem to blow engine.
Paccar is a disposable engine.

Nothing wrong with an SCR Cummins, just make sure the maintenance intervals were kept up. The fuel pump issue isn't an issue if the one you're looking at has the two head pump instead of a 3 head pump. Cummins issued a bulletin on it to replace them. I had a 2012 truck with a Cummins that did great; however, at 700k miles needed the camshaft replaced. I probably could have avoided that if I had inspected the cam shaft on a set interval.

A friend of mine is leasing a truck with a Paccar 13 in it and he is doing great with it. They make torque at a really low rpm and get very good MPG. I pulled for a fleet awhile back and all their trucks had Paccar in them. Other than a recall on a few that came up while I was there, they were very happy with them.

 

Same comment here too... Find an ISX CM-871, Paccar are throw aways... CM-2250 and CM-2350 have the exploding fuel pumps, AVOID. The CM-871 is a good motor, buy cheap and expect to in frame and rid it of the mandate. Been through it myself, once the issues are taken care of it is a strong running and very fuel efficient motor. You will easily get one million miles out of one if you take care of it.

Head over to Rawze.com... And no, it is not a cult, but a group of owners with a proven track record of helping other owners and saving more than a few from total disaster and bankruptcy. I am one of the lucky ones, as I had the sense to listen to their advice and avoided going under. These are not your grandpa's trucks.

 

Not true, the two head pumps with steel plungers and tappets are failing too... The issue is still there. I was just in the dealer the other day, he had a 2350 crated up to go to the scrap yard. It had the two head pump and steel plungers... The Paccars start having serious issues at that 400,000 mile mark by all reports. Failed crank shafts seem to be more common than they should be.

 

The biggie for an independent is there are ALOT more places to get a Cummins worked on than a Pacar engine. Just about any reputable shop will be able to do literally anything to a Cummins. Only Kenworth or Pete shops for Pacar motors even after waranty for the most part. No way as an one man show I would get a Pacar no matter how cheap.

 

Get a big horse Cummins.

Don't put a paccar engine into that truck.

At least the big horse cummins say 550 to 650 will help you when you need it and do one rpm all day long when you don't.

Since Im not really allowed to talk about other engine options I'll leave it here. But I cannot emphasize enough how important it is to get a big horse cummins.

 

Didnt cm2350 had improved fuel pump compare to cm2250 that had ceramic fuel pump?
