Why do Paccar Engines Have such a bad wrap?

I feel like three letter acronyms hurt the intial feedback on the MX-13. It first came out in 2010. The EPA required OBD monitoring to be on one engine model for every manufacturer, Paccar only had one engine. This lead to a MIL light that seemed to always be on with a laundry list of codes. Most issues were repaired by software updates or bad sensors. The EPA10 MX-13 tends to be sluggish off the line and I find it needs RPM run up higher than what Paccar recommended.
In 2013, EPA required stricter OBD monitoring on all trucks over 14,000 lb GVW. The MX-13 had a bunch of improvements including common rail injection, better control of EGR, a better logic when controlling the aftertreatment. In my experience, EPA13 pull better, get higher MPG, and have less issues vs EPA 10 models.
Resale is hurt for sure if truck is equipped with a MX. We have an 07 379 Pete daycab with over a million miles with C13 Cat and were offered same trade in number as 2012 386 Pete with MX and less than 500,000 miles! Market dictates trade in values.
My experience with the MX has been good. We run over 25 of them that are the 455/1650 rating and they do what we need it to do. I am lucky enough to have DAVIE, access to technical information, and good dealer support.

 

I'll give you four facts and a rumor.

1. The driving/power characteristics suck.
2. You are pretty well limited to paccar dealers for parts/service.
3. The basic architecture of the engine sucks. The camshaft comes out the BACK of the engine.
4. They have crap resale value.

My favorite alcohol-pickled psychopath mechanic claims that the compressed graphite engine block cannot have the counterbores re-cut. If you have a liner problem, forget cutting and shimming, throw it away and get a new one.

 

I considered 680's. The salesman at KW told me there's no extended factory warranty for the Paccar.

Is this true? Cause that's one of things that turned me off to them.

 

Not true.

Extended warranty coverages up to 60mo and 600k are available to purchase on the base truck, engine and aftertreatment system. Understanding what parts are covered under these policies is a whole nother article that most do not fully understand.

Certain major engine components as the block, head, cam and crank are covered for 5yr 500k without any additional warranty purchase.

 

You had a Look at a Volvo or Mack engine lately...????

 

I have read that the mx 13 has been around for quite a time and was originally built under the Daf 105 engine. Than paccar bought it.
The mx 13 is the only pushrod diesel made for north America.
I liked the way they run. But to many red lights issues.
And the radiator is only good for 300,000 miles.
Most owners I've talked to really like them.
The first generation had an oil problem from bad valves I think.

 

Paccar allready owned Daf trucks before they made the MX.
The MX had USA input.(example off that is the fact that the COE Daf and the North American conventional have the dame dippstick)

First sold MX's were 06's.
Def without EGR.

The oilproblem was actually not the valves themselves but the seals on the valves.
1 hour extra work when combined with adjusting the valves.

 

Why would that guy say that then? I was looking at used trucks. 300K mile range.

Or do you have to purchase it as the buyer of a new truck, and then it is not available for the second owner?

They offered that premier 2000, but that's not worth the paper it's printed on.

That's the beauty of the Detroit warranty as well. It's covered. Period. Just fix it.
