Question on DP Value after installing new Engine

[Scott98]

I have a 2008 American Coach that has 65K miles. Engine (425 ISL) was determined to be dusted by Cummins, and thus, was replaced by Cummins. My question is this: 1) How do you now determine value (new Engine was $40k). 2) Would you buy, or shy away from a Coach with an engine change.

Not that people have all that much faith in the NADA RV price guide, but it might be worth noting that NADA has always stated that its valuation for DPs didn't consider the odometer reading since the engines are designed to run for many more miles than almost any MH is ever driven. With that philosophy one could argue that the fact that your MH has a new engine is almost irrelevant since the fact that has low mileage doesn't make it more valuable than one that has more mileage. As a buyer I would be impressed that I was buying rig with an engine known to be in good condition, but I'm not sure I'd pay all that much more for it. JMO

Upgrades/options and even a new engine do NOT add value per se.


Good selling point but not much for higher asking pricing


Would I shy away from a rig with new engine.not under the conditions you described (Cummins replacement motor done by Cummins)
Provided their is accompanying documentation......but I would NOT pay higher price just because

If I was in the market, saw add for one with new engine my thought would run;
You had to replace a engine way before the end of what should be it's useful life? Why? Lack of maintenance? Abuse?
Think it would scare me...

But,
You might be "assuming" it was the owners fault the engine went south in the first place. Cummins, has had its share of issues in the engine kwirks over time, just like other builders. Some folks run and hide when they think of purchasing a motorhome with a CAT in it because of what scuttlebutt they've HEARD of the HEUI pump. Well, that's up to them. And as far as "Abuse", I myself am not too sure how one could "abuse" a diesel in a motorhome. Maybe lock it in first gear and drive it a across the U.S. at full throttle that way?

If we were in the market for a coach and, it had the layout and total parameters of what we were looking for, AND had a new engine in it, I'm not sure I'd worry too much but, might be asking as to the possible reasons for the new engine. If it ran good, and delivered the expected power at given rpms and times, why not?

Yes, I am assuming it was the owners fault, and would continue unless Cummins, (in this case) told me it was not.

Well, as much time as a MH sits, the engine could well be damaged by failing to monitor the condition of the coolant. Or by contaminated oil. Running low on ether...
A pickup with 250,000 miles and a new gas engine? This guy planned to keep his truck forever, changed his mind. Bet the rest of truck is in good shape. Same truck, 50,000 miles and a new engine? ....

Does it have a warranty on the engine? If so how long?

A new engine at 650k would be an upgrade. At 65k a downgrade for the reasons mentioned by previous posters. It raises questions about the reasons why, and the competency of the shop that installed it.

The unfortunate thing here is that the issue more than likely happened at the factory. The turbo/CAC connection had a bad clamp that allowed dirt etc. into the engine. I’m the second owner, the previous owner had the Coach in at 14k miles and it was diagnosed as having a “loose clamp” and “light dusting.” Unfortunately when I bought it at 20k, this wasn’t passed on to me. Ironically, the old engine had no performance issues leading up to the diagnosis. Regardless, that’s all in the past now as everything is new, and professionally done by Cummins.

The Coach was/is maintained well beyond what most people would do. I’m that guy that’s always working on everybody else’s rig as well. That in part is why I chose to replace the engine, rather than pass a problem to someone else.

Rebuilt/reman engine usually doesn't change the value of a vehicle. In the case of a CM 871 ISX it could be worth more if it was rebuilt with the latest Cummins parts over one that still has the original parts due to the failure rate.

[avfordguy]

Value is the same , good engine at 65k or reman engine at 65k..no difference. You may never recoup the 40 grand, just me!

What were the symptoms that caused you to bring it to Cummins?

Seems that a loose clamp on the turbo/CAC hose would leak boost pressure. How would this allow dust to be sucked into the engine?

[Scott98]

Coach was brought in for 1000 hour generator service as well as a check engine light that only materialized under heavy load ie., climbing a hill. Cummins did a stall check for blowby which has a scale of 1-20. Max threshold is 12 and it came in at 13. Would be higher under load. Performance losses were not noticeable overtime.

Well, I can see how that could happen. Part of my weekly service was inspecting the air intake system. Would think it would of been found when serviced.
And while reading on the net I have no doubt about what you say happened. OTOH, if you where selling the coach to me I would look at you just like any used car salesman. Remember, I'm not looking at the rig, so do not be insulted.
I don't think the new engine would be more valuable than a well maintained original, so if you are going to mention it you need to show documentation that it was done, but proof as to why
IMHO, the only way you will ever get that 40 grand back is use it until you get $40,000 worth of smiles out of it,
