Idling 6.4's

I just saw on another forum someone being told by a dealer that they were going to be denied some warranty payment because of too much idle time showing on the ECM readout. That these new emission controlled diesels can develop issues if idled.

It's true. The 2008 and newer diesel trucks have a soot filter (DPF) that will clog if you don't get it out on the highway often enough.

Indeed. Idling these trucks for extended periods is not a good idea. ESPECIALLY if the emissions systems are still in place. EGR coolers will clog(and are much more expensive to replace than they are to essentially repair on a newer 6.7)...the EGR valve will cake with soot until it can't open or close anymore. Of course the DPF will sit there and catch soot from idling and not getting hot enough to burn any of it off. Even passive regeneration is needed at some point. Passive = just drive the damn thing and get it hot for a bit.

well, if the FORD severe duty maint schedule is being followed, a local dealership is going to have a hard time with that sell.

thats why FORD has a severe duty schedule.

I'll have to go back and take a look at the service manual...but does the severe duty schedule even mention extensive idling? Or is it/should it be understood that extensive idling is covered under the sever duty schedule? Seems like if Ford didn't want to cover the issues that arise from extended idling they would have made some kind of disclaimer somewhere.

Or...as you mention...if the severe duty schedule is being followed...then a Ford dealer shouldn't be able to deny such a claim...unless "extensive idling" is not mentioned under "severe duty" work. Seems like "excessive idling" should be defined somehow. How ever many hours per oil change? I don't know.

I may have just talked myself in a circle.

Mine is on a motorhome chassis and is a 2012 model year without the diesel cleaning fluid system. It only has about 24,000 miles. I've just always cranked and idled my coaches in winter months to keep them fresh. I know I have to run the generator. I guess its better to take it down the road that just sit in the driveway idling.
