Turbo went out on a friend's Dodge truck.

The truck is 6 years old and he has about 60k miles on it. It is a Ram 2500 with Cummings turbo-diesel engine. Anyway, the place he took it wants $4,000 to fix it. I would have thought this sort of vehicle would have had a better power train warranty and this would be covered.

The truck is very lightly used, basically it is his daily commuter. I don't think he's ever hualed anything other than groceries with it. He did tow a Karmann Ghia about 80 miles on a rented trailer with it once.

I don't know what to say, but I find a lot of humor in a person owning a 3/4 ton pickup and hearing this

as I get more and more yrs under my belt and seeing pickups and the issues, I'll stick to my tundras.
 
How do you know it is out? Boost gauge reading 0 psi? Blowing smoke? Noise? Often people will blame a damaged injector for a bad turbo.


Changing oil is one of the biggest factors in the life of any turbo. Too often people get cheap on oil and this is what will burn up the turbo in my experience. Cheap air filters are another cause. Fix the problem now so that it doesn't go out again. Also seeing quite a few CAI and K&N air filters causing too much dirt to get by. The stock air filter really works best.

The shop told him that the turbo is bad and needs to be replaced.

Far as I know he maintains it by the book. His Dad has the same truck and he has had some problems with it too but nothing this drastic.

He bought it with plans on buying a fishing boat he could trailer but that hasn't happened yet.
 
Many shops are not familiar with the 6.7L Cummins Turbo and all the intricate details associated with this engine. The oil line running to the turbo not only tries to cool the turbo which can exceed 1800F degrees but also does its best to lubricate the bearings. This is why this engine holds 12 quarts of oil even though it is only rated at 350 horsepower.

You should be using a 15w40 high quality brand of oil such as: Shell’s Rotella, Mobil 1, Royal Purple, Amsoil, Valvoline Premium Blue, etc. Too often because of the 12 quart required fill, people get cheap and put in cheap oil that can’t handle the heat of the turbo. I would personally recommend either Mobil 1, Royal Purple or Amsoil. I’ve also seen many people just add standard 10w30 oil they have around their garage. Even quick oil change shops often will get cheap and put in cheaper oil.

There are specific Cummins boards where they discuss this subject ad nauseam. You would do much better getting advice on those boards than on a IT type board. I do both, which is why I am here.

That is sound advice. Also if the truck already does not have one, consider adding an engine oil cooler.

Stick with what you know.
All cummins engines are 12 quart since the B series started.
The 6.7 turbo is water cooled.
