Thoughts on Paccar engines

Thoughts on the Paccar engines appreciated. Amongst the trucks we're looking at this weekend are a few Pete 575's.

My company has several Paccar engines very rare to have them in the shop. We have 2015 to 2018 4 are Peterbilts and 2018 is a Kenworth  

I'm finding that all over the web. Engines, it seems, is are like asking what oil I should use? Facts indicate that some engines were/are more problematic (D16 for example) but most 'opinions' on motors are just that. You have first hand knowledge which carries weight. Would be nice if there was a compiled database or chart showing reliability across the spectrum.

Hopefully not rationalizing here, we won't put a lot of strain on the drive train pulling a 20k or less trailer. Maybe the Paccar (if in good shape when we get it) could be an option. Hmmm. I understand long haul drivers who pull the hell out of the equipment, being skeptical. As one driver said when he tilted the hood ..."oh, Paccar. Not making any money with this truck." And that's telling of their valid focus, right or wrong.

The Pacar engines IE DAF are as reliable or unreliable as any tier 4 engine with aftertreatment. 

 

Every manufacture is learning the weaknesses in their product line as the systems mature.     The older the engine the more likely the system has known issues.     The newest engines seem to be getting better just like spark ignition engines when emissions were first introduced.     That said, unless you buy a new truck or one with warranty time and mileage you are assuming liability for the emissions system.      That is the area where "engine reliability" is most fraught.      There are engines that are known for breaking cam shafts or cranks but, the reality is an engine that has 600K and no major component issue IS reliable.      The aftertreatment systems are the area where reliability fails.     A truck in commerce with 100K that sits at a service bay for three days every other month is NOT reliable.

 

The newer trucks have some really nice features and in general have good engineering.     The systems are complex and do have issues of their own.     Adaptive cruise control and lane departure, traction control, automated transmissions are all wonderful systems.     They also add levels of technology that can and do fail, not regularly but, when they do they are often costly and time consuming.      

 

The choice we face with any vehicle purchase is what we want Vs what we can afford.     Newer obviously is highly desired by most for the new tech and lower prior use.    For people looking for an RV hauler, either a pre-emission truck or the newest you can find would be generally be prudent.     In summary then it is either pre 07 trucks without dpf or 2016-17, the mid years 2008-2014 should be avoided.      I would also say avoid ANY truck that has been "deleated" while it may sound good on paper it is not.

The Paccar engine is a Frankenstein engine; unlike Cummins and Detroit, which are designed and manufactured in-house.  All you have to do is to go to Truck Paper and search for just about any similar truck make and model.  Trucks with Paccar engines are almost always discounted when compared to a Cummins, Detroit or Cat.

Of course, there will always be exceptions to the rule.  Obviously, there are folks out there buying the Paccars.
