i see.

cincy, you're a clown. valve stems are on the tires knucklehead not under the valve cover, everyone knows the turbo disconnect is the thing under the valve cover.

 

You can idle for extended periods with no problems as long as the engine temps remain fully warmed up.

In cold weather you'll have to increase the idle rpms to keep the engine warm. At normal idle rpms the engine doesn't generate enough heat and can easily be kept from fully warming up just by idleing in cold temps.

During the winter (20* out) I'd be driving home on the highway with the engine fully warmed up. Then hit bumper-to-bumper traffic and that temp gauge would drop to less than halfway in no time just from sitting, idleing, in 20* weather.

You can do this the old way with a sawed off broom stick between the seat frame and the go pedal, or the new way with the variable high idle cruise control feature, which has to be enabled with a dealer reflash of the truck computer.

As long as the engine is warm you should be able to idle that thing indefinitatly.

There are members on this board who live up in Alaska and NEVER shut off their CTD's during the really cold months.

That's 24 hours per day, 7 days per week.

That's what I call EXTENDED PERIODS!

The problem is the engine temps won't stay up there at an idle and the colder is the lower they drop.


Nope, not true. Engine temp is not the criteria that is important, combustion temp is. A CTD will have warm coolant temps and too low combustion temps to stop wet stacking. Thats what a coolant system does, remove heat from the combustion chamber and surrounding areas. Too much heat is taken away at no load low rpm's.



Not and expect their engines to last as long as they should and not idling. You CANNOT putter around and idle these engines for long periods or there will be problems. The colder the temps the worse it is on the engine. Broom handle, high idle, etc, don't cut it unless the EGT's stay high .
Ten months out of twelve there is NO reason to extended idle a truck in the lower 48. The other 2 are only marginal.

DC does not warranty these engines for severe duty in a light duty truck. Cummins rates severe duty by hours-to-miles comparisons. If you have less than a 35 mph average you run the risk of warranty denial. There is just too much evidence extended idling is bad to ignore.

 

Of course you can use coolant temps to determine whether the engine is warm enough for efficient combustion.

Everyone [ except you of course ] who is concerned about NOT idleing unless the engine is warm enough uses the coolant temp as the indicator.

Way up north these engines are idled 24/7 at rpms high enough to keep the engine clean and keep the fuel from washing down and contaminating the oil. And those people use the coolant temp to determine how many rpms to add to take away to keep the engine in the right temp zone.

This has been the practice for years and they *still* do it so it can't be doing much harm.

If the engine stays warm enough ( coolant temp >= 175* ) it's safe to idle for extended periods.

Yeah? Ford owns Cummins too, right?

Mr NEWBIE, I suggest you do a little more reading before posting totally contradictory, and blatantly wrong, info in the middle of a thread. While your at it you might want to do a little testing on your own. You might learn a few things.

Not sure what your game is, but, if you want to TROLL have fun playing by yourself.

 

[QUOTE=no_6_oh_no;1557440]Yeah? Ford owns Cummins too, right?

That's a really good point. Right on subject.

BTW, ever have a problem with ADD? They say adults can have it too. You should have that checked.

Rather than go back and forth on the subject with me alone, you should research it on this site.

Then you'll have many more people to disagree with .

I have a bent oil pan on my 2004 dodge ram diesel 4x4 quad slt. I was told by one mechanic I should spend $1200.00 bucks and fix it. He said I have to lift the engine to do it.

Another mechanic told me that It wasn't hurting anything because the engine is not starving for oil. He said the oil pressure increases when I give it gas so that is a good thing indicating the veh is getting oil.

Thoughts on fixing this?

Any ways to bend it back on the vehicle?

Its bented up about 2 inchs...Nothing is hitting. I put about 200 miles on it before I knew it had a bent oil pan.

Roger...

 

I bent one myself and fixed it by putting wood blocks in the pan and jacking up on the bottom. You will have to make something so it puts the pressure in the right spot when your jacking it back out. I did have to raise the engine to get enought room to put the wood blocks in the pan. Make sure the wood is sitting on something nice an solid and not your pickup tube. Clean the pan once done very well as the wood may splinter. If your like me you just dont want to pay some guy 90 an hour at a dealer ya know.

 

Oh yes as for the idling this thread started out with. I have 2 trucks and 05 and a 06 that idle overnight, all weekend all the time and I have never had a problem from it summer or winter. Although when idling in the winter in the north we do block off part of the radiator and have never had the high idle enabled on either truck. The 05 has over 194k on it and the 06 has over 187k on it. You will notice some smoke when you takeoff after long idles and that is cause from raw fuel as they said before. Neither truck has ever used oil and don't use oil now. I know of 5.9's with over 600k on them still running freight that idle when parked at truck stops so for the average guy that idles once in awhile or allot like we do, I wouldn't worry about it at all. As far as the truck being in neutral to get fluid to the TC that’s not true. The pump is running 100% of the time and does pump fluid through the system while in park.

Right on Mark.

For all the yammering that goes on about how extended idling can damage the engine I have NEVER heard or read about *EVEN ONE SPECIFIC CASE* of damage done by extended idling.

Just doesn't happen.

Maybe, it will shorten an engines lifespan by 20000 miles but if so, I bet those 20k miles won't come around until the odometer reads at least 980,000.00.

I run with a radiator binky during the winter. Best 100 bucks I ever spent. The truck gets toasty in no time.

DT.

 

This may be too simplistic, but I bought a little rod at a truck stop that hooks on the bottom of the dash and goes to the accelerator for about $3. It is adjustable at the place it hooks to the dash, and I use that to set my idle wherever I want it to be.

 

I have a 04.5 with 300,000 miles on it and I let it idel for 8hrs a day with no troble and leave it in park with no problems at all.

 

Looks like I need to use spell check before I send a message.

 

You know I've been reading allot about all the guys with the new 6.7's. Looks to me like idling a 6.7 will clog your cat up. Man I hope they get a work around that because upstate Wisconsin and Mi. gets very cold without your truck idling allnight while you sleep not to metion what Phoenix is like in mid Aug. without air EEEEEEEEPPPPPPPPP. Think I'll just keep my 2 5.9's till they work that bug out. I'd say it will be like 2009 or 2010 when they get that worked out heh. I hate being the test subject at my own expence. When I twisted my 48RE's input shatf off into 4 peices it was 5 days in a truck stop parking alot idling air in the day an heat at night just West of Vail Co.with all the cat regen problems the 6.7's are having I just dont think one would have lasted 5 days of idle time.

I think I would be using the cat removal tool made by Miller or Lincoln
