Any opinion on the 6.7 engine?

[RVTRKN]

The first major issue! Was when D/C learned that the turbo's needed to be cleaned and techs had to drill a port in them to facilitate the cleaning, with the later turbo's having them designed for cleaning, which eventually were replaced with the new turbo's, if you had a CEL due to turbo sooting up. So back to the OP's question, if you purchase a 07. 5-08 6. 7, make sure the turbo was replaced with the newer model.

I never gave it much thought but I did notice the sound of the turbo when using the EB changed from a whine to more of a growl just before I traded in the 07. 5. Since there were no CELs or other issues I never did anything about it. It wouldn't surprise me if I learned that my old truck is on its second turbo by now.

That is one of the single biggest drawbacks to the VGT turbos, they will soot up and stick. Running them hard and using the EB helps MTBF but at some point it will be an issue. So far there is no solution for it with the emissions requirements.

Along with propensity to blow head gaskets and the cost fo the emissions junk when it fails, it really makes these trucks a "leave them stock and trade when the warranty is up" purchase. Good or bad, it is what it is.

I'm curious. Do you own or have you owned an '07. 5 - current 6. 7L?

I am curious, why does it matter?

For reference, I have several acquaintances that have\had a 6. 7 and have had 1 or more the issues defined in this thread. Their choices were go back to a 5. 9 or routinely trade the truck. Downtime sucks when the truck is the livelyhood, it is even worse when one is on a budget. Nobody denies the engine is strong and reliable to a point, it is unanimous the controls and emissions are the root cause of the bulk of the problems. Not much choice there, live with it or rely on warranty.

I have 2 HE351VGT's on 12V's. They stick routinely because of everything I pointed out. A 350 HP 12V is a lot dirtier in the exhaust so the problem is even worse.

As I stated earlier, I was simply curious. No offense intended.

None taken. Just wondering if there was a specific question.

Wow. What is a CEL? IS that a recall by Dodge to fix a factory bad idea? Just never heard that one before. So the update turbo have an access panel visible when looked at? Thanks for the bunch of info. I may just keep my 1998 12 valver. LOL

 

[HerbW]

Oh, the truck I've looked at is still for sale. Truck sales seems to be at a stand still. Two others I've looked at are also static and they even lowered their prices.

Thats the sad truth about D/C, they know they fail, and instead of a recall to install the Turbo that can be cleaned, they wait for failure. To compound the problem, they drill into the early model Turbo's, knowing you will return with the same CEL and THEN replace it with the current model.

Actually the new procedure they have developed for cleaning the turbos has a much higher success rate than the old one

Any details on the new cleaning procedure??

Are you talking about the first Turbo without the cleaning port?

 

[Bob4x4]

Ok instead of just spraying the cleaning solution in the hot tubine housing while running.
There is a scanner driven procedure where the engine is at operating temp of course and the scanner operates the slider while the cleaner is sprayed in(engine not running)
Doesn't matter what model turbo-

The drilling and Tapping if done correctly is a non issue.

 

[RVTRKN]

Good info.

I don't know, I've never had my turbo cleaned, it's never been touched. I did have the head gasket changed, by mistake. The dealer said the head gasket was blown, changed it and I had the same problem, blowing coolant out the over-flow tube. Turned out to be the EGR cooler. Changed that, problem solved. This took place at around 130k miles. Because of the type of work I do, I decided to get rid of the only problem causing area I was having, I completely deleted the truck, I have had no problems since. It seems Dodge has solved the emissions problems in the later trucks, if I were to ever get a new one, I would probably try to leave it the way it came. If the emissions started giving me a lot of down time, things would probably start falling off. Getting a new one when the warranty is up doesn't make sense $ wise to me. If I were going to do that I would get a gasoline engine and save the difference between gas and diesel. That won't happen, but it would make more sense.

Mine has never been touched either and still has all the OEM hardware attached. The truck is long out of warranty and I have no plans to replace it . . . ever. My truck is, of course, a cab and chassis, by plan. Less emissions crap was one of many reasons I bought it instead of a pickup. But it has never been subjected to service as a grocery getter.

I just have to throw my two cents in here. I purchased my 07, 6. 7 RFE in and took delivery 7-17-07 so you can see this is one of the first. It’s a 2wd DRW Pick Up truck. I’ve never driven it as a ‘grocery getter’ and it works at least every two or three weeks. When working it operates at a 23,650 gcwr. At the time the deciding purchase factor between the 5. 9 and 6. 7 engine selection was the new auto transmission. I just had to have it! Prior to that my standard transmission Dodge’s were 5 speeds and I just hated that flat spot that was there when trying to accelerate under load from a stop on a grade. You know the place where you just can’t get it to pull to the next gear. My earlier Dodges have always had clutch and transmission issues, probably because I was operating at max gvw and gcwr’s. I’ve been a TDR member for many, many years now and have followed the development and problems reported here. I’ve followed all the advice and carefully updated the software as it was issued and low and behold I can say that the truck has never been in the shop for anything other than regular service maintenance ie oil, filter changes. Of course there is no cleaning plug in the turbo so nothing has been done or needed in that area. Perhaps it will happen eventually. I did purchase the extended warranty as that was recommended because of the new engine and transmission. Turns out I’ve never needed it! John Holmes, when he was at Carson Dodge, helped with the selection and purchase of the truck. I went against his advice and purchased the 4. 10 axle ratio and have never been sorry about that decision. With the new auto trans it is sweet. The truck is still bone stock.

So there you have it and I can’t say anything negative about MY truck. I tend to agree with Harvey. If you’re buying a truck of any kind do everything you can to assure yourself that you are purchasing a truck with a clean history. Any truck can be a problem including later models so do your homework. Ted

Hi. I'm thinking about buying a 2007. 5 diesel with a 6. 7 engine and automatic in it. I have now a 1998 12 valve diesel. The reason I want to go newer is the regular four doors, newer six speed auto transmission and factory rear disk brakes. Is there any good mileage with the new engine? How about depenability, etc? Any ideas are appreciated. Thanks, Herb

Herb,



After all the advice, suggestions, and arguments have you been able to make a decision? Are you still interested in purchasing a 6. 7L? Regardless, I hope you find (or keep) what you need.
