High idle hours?

Lost of hone marks? Hopefully once the engine starts and runs the hone marks disappear and not be felt with the finger nail. The only reason a block is honed is to aid in seating of the rings to the cylinder wall and final sizing of the bore to piston clearances. Hone marks are not deep enough to hold any oil of sufficient quantity to worry about dilution of the oil on the walls or from the piston cooling oil that is sprayed into the pistons to cool the tops.

In reference to is it better to idle, not for the diesels we have today. I still do it from time to time especially in August when I want A/C relief from the southern humidity or I've used the two minute "rule" (not that there's a rule) for a long time which even that thinking should be reduced.
Plus, if you use remote start, it's already idling quite a bit over time. If it's remote started from inside the house, maybe you get distracted and five minutes pass by for example.
Idling begins to slowly clog the EGR inlet (butterfly valve area) because their is oil mist in there to help it stick, those smaller EGR pipes, the EGR cooler and eventually the DPF (but at least that can self clean (more fuel) unlike the EGR cooler).
Even idling my tractor (no DPF or DEF) has resulted in 3% fuel in the oil in the past.
The company I work for spends quite a bit of money with UPS where I've picked up a few bits of info over the years and they data log and analyze everything they can put a sensor on (telematics for the vehicles) or get metrics from. UPS's data analytics with folks who know how to utilize that data are actually one of their advantages. They have determined it is cheaper to replace starters than it is to pay for fuel and other wear from 10's of thousands of idling trucks. In addition, it is expensive (especially depending on the package contents) to have a truck more easily stolen so that factors into the consideration as well. UPS has said they proactively replace some parts anyways, such as starters. UPS will market it as "green" and "reducing our emissions" but it comes down to idling at their scale is a colossal waste of money.

Back to the OP's question though, personally I would not let it change my mind about the truck if everything else about it checked out.

True stories about premature DPF and EGR issues as well as diesel dilution and sooty oil. I would stay away from it.
We just finished a 6 month hunt for the right truck. 92000km, 1218 hours, 104 idle hours is 8.5%.
They are out there.

I assisted with the distraction. To the OP, it does have a decent amount of idle hours for the total but you could get a used vehicle Ford Protect (ESP) warranty for it and not worry about it especially if everything else with the truck is great. Even if you don't, realistically the first emissions component that could have an issue around 100,000 would be the EGR cooler and it's replaceable. A few members here have reported needing two or three replaced by the time they reached 100,000. Mine was plugged by 105,000 with 22% idle.

I went back and calculated the idle hours on my truck (bought it used) since I've owned it. I'm at 24% and I drive a lot of highway miles. Kinda surprised me that it was that much. I don't do any what i would call, "extended idling" other than normal stuff like picking up kids at school, drive throughs, etc.
The '17 is really nice and seems to have been very well maintained. When I bought my current truck, I didn't understand or even know about idle time percentages. Turns out it had a higher percentage than the 17 I looked at. I haven't had any issues with my truck at all but I did lose the rocket ship under the truck after I hit 100k. Did it as a proactive measure.
