EGR Failure on 6.7 Power Stroke

[FishOnOne]

Here's a video on a EGR failure on a 6.7 PSD. I'm surprised of the idle hours this guy is reporting.

If properly equipped they should have a fast idle setting. Where I work we only idle if we need emergency lights running or if it's extremely hot or cold out. Otherwise we shut them down whenever parked off-street. Same thing with the big trucks, no need to keep them running if you don't have to. Some of our newer ones have the ability to run emergency lighting off of an on board generator, so they only need to run the main motor if pumping.

High Idle just prevents wet stacking and I doubt will help much with the EGR system.

Even at a multiple vehicle crash scene with multiple extrications and or waiting for the Coroner unit to show up your looking at 4 hours tops. All these units have the ability to idle up when sitting for extended periods. At a scene the units at least ALL I have been involved with and seen for that matter stay running until they arrive at the hospital or back at the station.

If the Ford can't handle extended idle time, then Ford should stop supplying units for EMS/Ambulance use IMO.

Don,
Ignorance is a bliss... You want to fire this chief? Link

BTW... I can understand your post full of angst since RAM owns 8% of this market and Ford owns 68% of this market.

Sincerely,
We Own Work....

Suspect a high idle isn't nearly enough to keep an EGR from failing over time with the overall amount of time an ambulance spends idling, though the hospitals in my locale finally got wise and require the ambulance jockeys to shut 'em down when they are parked at the ER entrance offloading.

"hammer down until the smoke clears out" ?

This his way of keeping the EGR clean. New diesels DON'T SMOKE !

If they are worried about running it cold (Not likely in Atlanta) use the block heater!!
2,500 hours in 120,000 miles, that is just under 105 DAYS of idling time WAY TOO much!
This post is bit, misleading, in that it a case of extreme abuse!

Umm. It's not just the cold that makes one idle a vehicle. Y'all have any idea how hot and sticky it gets in Atlanta in the summer. 110° on pavement will kill you just as dead as -40°.

Yea, I agree, funny how right in the power stroke manual it states not to idle the engine for extended periods of time.
Not surprised the EGR failed, it has hot exhaust gasses constantly flowing over it.

[thomasmnile]

That the EGR came from an ambulance certainly explains why it failed. That's a bunch of idling time, but if the ambulances are constantly on the road, either on a call or being shuffled around town for coverage purposes (and idling in shopping center parking lots, etc & not based in a station), that kind of idling time isn't unrealistic.

Idling a diesel to keep it ready to go makes a certain amount of sense . . . in Anchorage, Alaska. In Atlanta, however, it is what is gently referred to as "a h*** of a stupid idea." If there is any place on the planet where it ought to be easy to start a diesel any day of the year, that place is Atlanta. Atlanta, where 1/2 inch of snow closes EVERYTHING. Atlanta, where a bitter cold snap gets down just below freezing. No wonder that EGR cooler was clogged up with carbon deposits.

Yeah, idling a modern diesel engine "to keep it ready" makes no sense at all.
