6.4L Power Stroke Engine and DrivetrainDiscussion of the 6.4L Power Stroke diesel engine and drivetrain in the 2008 Super-Duty trucks. No gas engine discussion allowed except on transmissions and drivetrain that pertain to all models. Please confine discussion of topics in this forum to those items that are specific to the 6.4L Power Stroke engine.
Every truck I have owned or used for work has been subjected to long hours of idleing. I've never had a single problem with any of my trucks from idleing, I've heard on this board that it can cause "wet stacking". I don't know what that is but it's never happened to me, I let my trucks warm up for 10 or so minutes on cold days and when I'm out on my jobsites our trucks usually idle all day long to keep materials for weatherproofing warm or for using the inverter for running a winch or electrical tools. Heck, they put a PTO on these trucks, I've seen Utility companies never shut their trucks off until they are done for the night. Has anyone ever had a problem with "wet stacking" or is it just a bad rumor? I know someone is going to say that it's wasting fuel but my response to that is to come on out with me and when you get down from being up 300' on a tower your glad that truck is warm.
On engines with HPCR injection excessive idling can cause the injector tips to foul up with carbon. There was a post on the Dodge board about a guy who's warranty was voided after injector failure. Supposedly the computer logs idling time as well as total hours.
You might consider using an additive like "meaner cleaner" on a regular basis if you do need to leave the truck idling. I guess the newer engines are more sensitive than the old mechanical injection systems. [img]/ubbthreads/images/graemlins/shrug.gif[/img]

In theory, practice and theory are the same.
In practice, they are not.
Wet stacking is the terminology used when an engine idles for a long period of time, and the stack on the exhaust system actually gets wet from fuel. This happens when operating temperatures go down and fuel burns inefficently causing the cylinders and exhaust system to load up with fuel. The modern day diesel doesn't usually have this problem, they have (an idle up switch) that will idle engine at 1000-1200 RPM to operate a PTO or pumping system.
VGT and idling is not a good marriage, it causes the turbine vanes to gum up.
It must take a lot of idleing time to gum up the injectors then because my 97 had 280,000 miles on it when I sold it and probably a gazillion hours of idleing, I left that thing running all the time. I try not to leave trucks idleing if I don't have to mainly for fuel savings. Have you ever seen a truck that had problems from excessive idleing?

Personally?...no, just relating what I've seen posted by other owners. However, keep in mind that HPCR systems are relatively new and may be more prone to getting carboned/gummed up than the HEUI or straight mechanical injectors. I hadn't considered the VGT turbine getting gummed up, but that would also be a concern.
PS: I've never seen the Space Shuttle either, but I'm pretty confident that it exists.... [img]/ubbthreads/images/graemlins/wink.gif[/img]

Your '97, mine also, doesn't fit the stated criteria for
trucks prone to idling problems.

I think Low speed idling is the real problem here..
Low oil pressure
Low coolant temp
Low and very unhealthy E.G.T.'s
These things all lead to Wet Stack or slobbering as I call it. Kind of like when You roll into the truck stops in the middle of a below zero night all you can see is a blue fog..
If you must idle your pick-up, kick the idle to 1000 or so.. On my CAT I park with back to the wind and Idle to 900 and the pyrometer will usually hold 300 or better....

Yes i have,been turning wrenches longer that many of you been alive,the modern day diesel no,but 25/30yrs, Cummins,Cat and Mack had a problem with wet stacking and fuel dilution when idling all night,the coolant temp. would drop below 100 degrees.The fix was to kick up the idle speed to 1000/1200RPM,vrs.idling at 600,for long periods of time,engine temp.would come back up to 180 and the wet stack would be elimated.
What is that "drone" sound I hear at the local truck stop late at night sounds like about three hundred diesel trucks idling, unless they have APU's on them. Does not seem to hurt them.

The drone you hear is damage to the engines unless they have some sort of idle control. The drone you hear is the lamenting of the actual owners of the trucks that pay for fuel/oil dilution AND wasted fuel. The drone you hear is the illegality in many states of extended idling.

With the 6.4L (and any truck with a DPF), extend idling also increases the length of the regens. This can lead to extra fuel dilution in the oil, and more fuel consumption.
Youve never seen the space shuttle? Not even on T.V.? You are the only one my friend. Can someone please provide a link to a picture of the space shuttle for this gentleman? I do like the comment though, it made me laugh.
"the modern day diesel, no, but 25/30 years, cummins, cat and mack had problems..."
-------------------------------------------------------------------
I appreciate your responce slide5th, todays powerstrokes idle up on their own, but my 97 didn't, I saw condensation all the time dripping out of the tailpipe, is that "wet stacking"? If it is, it never did any damage, what does wet stacking cause? Apparantly it's bad for the motor. I travel a lot and tow a gooseneck all over the midwest, I hit a lot of truckstops and pretty much every truck there is idleing, matter of fact, these truckers probably never shut their trucks off in the winter except when they are home, why don't they have problems?
You said 25/30 years ago, but the comments on this site have always been about all modern day diesels, what are your comments on that?
"the drone you hear is the illegality in many states of extended idleing"
__________________________________________________ ___________________
What "many" states are you talking about? California? Heck, you can't do anything legal there. I have never heard of such a law, and IF it exsists than why have I never heard of or seen someone getting a fine for such a thing? You would figure truckstops would be a goldmine for authorities to write fines. That drone is also keeping heat rolling for that truck driver that was driving all day and wants to get some shuteye without freezing his butt off and not getting enough sleep and possibly causing a pileup because he is dog tired. Now that is illegal according to the DOT, you must rest after so many hours of driving. I want the truck drivers I am rolling down the road with well rested, don't you?
Why is it those trucks can idle all week long without any problems yet everyone on this board says it will damage our powerstroke/cummins/duramax equipped trucks?
I understand the new technology and the delicate injectors, but why have I never read a warning from Ford/GM/chrysler/etc on extended idleing? You would figure someone (other than the patrons on this board) would say something. The best thing about all the Ford trucks I've had the pleasure of owning/driving for work have been extremely durable, I've been able to do whatever I've wanted to do with my trucks with very little consequenses, I constantly tow well over the weight limit I'm supposed to, I've had to pull trailers up steep logging trails to get to my sites, I've idled my trucks all day long on cold days for as long as I can remember and I've always been able to make my trucks last for a lot of miles, I had 282,000 miles on my 97 when I sold it in November, well, it has over 300,000 on it now. I'm just trying to get an explanation from somebody that has had a problem from extended idleing. As for the 6.4 powerstroke, I've read everything about these trucks and never have I read about damage to the engine from extended idleing. Have you read something about extended idleing on the 6.4?
