6.7 Extended Idling

Hello all I am looking into the 6.7 and was wondering does it have the same problems from extended idling as the 6.0 did.

If you do the high idle mod I wouldn't think there would be a problem.

it should be fine, i let my mine idle for air for my black lab's! u bought a commercial truck right. i see service truck's do it all the time with the 6.7,that's y there's an idle engine hrs. time keeper, cause you need to change the oil a little more often, that's all!! owners manual should have the intervals,for long idle trucks.

the local EMS provider in our area (hundreds of ambulances all fords) just stopped ordering diesels and went back to gas. Emissions problems with new engines, cost of new engines, poor fuel mileage etc.....

They run the 7.3's 350,000 without problems.

This thread interested me because I have a 1,300 mile trip from Texas to Michigan coming up and was planning on sleeping at a truck stop in Tennessee. If I let it idle 6 or 7 hours at night (after running all day) will it hurt the engine?

After getting back on the road it will be back up to 70MPH until I need another tank of fuel. Basically it will be running straight for 24 hours (with 6 - 7 hours of idling in the middle) and I don't want to shorten the life of a new engine.

This is my first Diesel truck and I don't quite know all the rules and I don't have SEIC as I saw was recommended for extended idling so I just wanted to get some opinions from people running diesel a lot longer than me.

Thanks!!

This engine has a much better EGR system than any previous engine. The EGR valve was moved from the EGR cooler outlet to the inlet in this design, in other words the valve only sees the hot exhaust rather than the cool side of the heat exchanger therefore the problems with deposits and coking on the valve are eliminated or at least significantly reduced. Like said above all it should really mean in practice is more frequent oil changes

You shouldnt have a problem letting it idle for 6hrs. It would be better if you have a High Idle switch though. Anywhere from 1,000-1,200RPM's. I Idle my truck often, no problems. Diesels are made to run and stay running, that's why we bought a Diesel.

Ditto, I think I still have more idle hours on the truck than running hours even half way through summer.

My truck idles for most all 12 hours a day. No problems. High idle mod will help.
But i also deleted that ridiculous exhaust. 5" straight pipe w/ H&S mini maxx. Overly impressed...
Guys i work with that have 6.7 co. Trucks still have dpf on them idle them 12 hrs a day, everyday, blows blue and white smoke out when they leave.
The only thing that worries me is injector wear and tear... any feedback on that?

I am aware that there is a intelligent oil life monitor on the 6.7 but I would resort to a 200 hour maintenance schedule if the vehicle is idled for long periods. Better safe than sorry when dealing with a $14k engine. Maintenance schedule is here: Power Stroke Diesel - Power and Pride

I work for an EMS provider here and they're starting to use gas as well, but time will tell how they hold up. It's fun to watch the pile of black shoot out of the exhaust when you idle a diesel rig for 4 hours straight and then try to go really fast though.

You do, you just don't have the dealer installed wire between your upfitter switch and the PCM input. Go here, follow the instructions. The resistor and wire should set you back about $3.

6.7 Extended Idling

I idle mine all day long in 105+ temps when working outside and it's nice and chilly inside. It doesn't skip a beat. I use Mobil 1 for diesel, OEM filters, change em on the extreme duty schedule ( or sooner) and trust it to go around the world.
