excessive idleing

[jonathanwayne18]

just want to know what is considerd excessive idleing for my 7.3? or does idleing alot hurt anything. for instance today my truck idled for about 30 min while i shot bull at a buddys house, and i always let it warm up for 10 to 15 min in the morning.

30 minutes wont hurt anything. Ambulances idle all day long. If you plan on letting it idle alot id get a high idle mod done to it to prevent wet stacking.

Letting it warm up for 10 to 15 minutes every morning is a waste of fuel.

ive got high idle on my tuner but also when my truck idles for about 2 min it automatically idles up to 1000 rpm. and also i let it warm up in the morning because its been about 25 deg. in the morning and i love my heat!

I wouldn't be worried about wet stacking as much as long idling causing dead spots in bearing lubrication making engine life dramatically less.

not if its really cold

Even if its really cold 10 minutes is a waste.

And ive never heard of idling causing dead spots in lubrication.

"dead spots" are when due to the lower oil pressure the oil in the bearing areas may not circulate correctly.

I understand that but thats only if your oil pressure drops way below a safe level. Our trucks wont drop to that level while idling. We carry at least 20 psi at idle with warm oil, that is plenty to keep from getting dry spots.
