Good look with the spousal relations, I have no advice there. I finally have my fiance understanding that she needs to idle her truck (Cummins) a bit before shutdown. She didn't believe me until she finally read the manual and saw that it stated exactly what I had been telling her.
I can't get 30+ mpg in them hills. I consider most of the driving around Lake OZ to be town.
Thx for the clarification....that's good to know....it's hard enough to find a good service dept for "common" gas vehicles, even harder for common diesel vehicles, but it's next to impossible to find somebody who is knowledgable about something as rare and unique as our CRD's.....thx again for the info....I'll keep Grubbs in mind....

I guess any first time diesel owners who were not early buyers must have installed a provent at time of delivery or don't expect to own it long. We were not that lucky.
Over 20k miles, no "broken in" benefit. Best mileage when not using local crap diesel. Would love some 50 cetane.
What was your $8-9 intake fix you referred to in an earlier post? Where did you re-route to intake to? I remember Mercedes diesels in the 90's that actually had an air intake grill in the passenger side front fender, I guess to pull in the coolest air possible....I haven't checked my air filter yet, as I've only got about 3K miles....I will check it this next weekend, and may try to re-route the intake then.

I had a Silverado with the Duramax a few yrs ago....changed the fuel filter the first time at 15K, and immediately saw my mileage go up 1-2mpg.....has anybody had their CRD long enough to replace the fuel filter, and if so, any noticable change in power/mileage?

3"-4" plumbing rubber coupling and 3" male pvc adapter. This replaces the airbox inlet tube and surrounds the piece attached to the radiator brace diffusing the draw of the turbo and keeps road grime off the filter.
That is not an issue for most people but if you look at your filter and debris clogging your drain holes in the airbox you'll get the picture. My airbox stays clean and no water on the filter.
I bought the CD also. It is sure
enough a good copy of the shop
Manual. I also bought a parts list
CD.
Good luck! LK :shades:
Dave, are we talking about the same vehicle? The fresh air intake on my CRD is just left of the right headlight behind the grill. The bottom of the opening is 31 inches off the ground. I haven't driven through 2 feet of water yet but I have driven in heavy rain. I see no evidence of water getting in my intake or on my filter.
My problem is this, there is oil all over the hose. I am pretty sure this is not as it should be. The dealer ordered a new hose, but what causes the hose to be so oil soaked on the outside? Any ideas or suggestions are sure welcome.
One dealer I called told me it was the transmission cooler line, and of course one tec said it was a water hose! And DCX has trained these CRD dealer tec's?
I did change my air filter as it was really, really bad. Put a fram in, cost $11.30. but at least its a big one.

I agree with Bvcrd that it is a loose hose clamp or a loose CCV hose. Could also be a split intercooler hose but that should result is a loss of power and maybe make a rushing sound as air escapes. Eventually the hose could pop off completely.
If the hose is okay it needs to be removed and the mating surfaces of the hose and the pipes made very clean on each end so it won't slip off under pressure due to slick oil.
Anyway, you now know first hand what we have been talking about concerning oil in the intercooler hoses.

I have tried that, but my wife has no interest in my CRD what-so-ever :-) To her, it's "just like her Trailblazer, but noisier"....which is why she doesn't get to drive it!
That's why I enjoy this forum....get to talk to others who get excited about their vehicles and enjoy sharing experiences and advice. Thank you to all who have posted over the months....I've gotten a ton of great info from this sight!

There is nothing to worry about except getting you dirty when you reach into the engine compartment. These oil fumes diffuse everywhere and this is why we have hoses made of a special material that resists to cracking.
One of my headlamp connectors was destroyed because of the oil fumes. The plastic moulding around the contacts of the bulb just came into tiny bits like if it had burnt. Wires are usually not affected but tape doesn't resist more than 5 years. Tape just peels off because it doesn't stick anymore.
I watch the weather channel. Talking about an air intake that is vacuuming the asphalt implies an air intake that is 10 inches off the pavement - like little cars. The air-box and intake is nicely integrated in the CRD. The intake is open around the headlight and should not suck water, it can only be pushed in or just be that high. You are not going to get any higher under the hood, realistically.
What you need is a fording kit or a bigger vehicle. I had the impression the intake was poorly designed until I looked at it.

It's also due to the "migration of the plasticizer agent", in other words the substance that gives flexibility to the hose has a certain degree of freedom to move. The warmer the better.
And, something else, the intercooler hoses on my CRD are lined with what appears to be Teflon or urethane, not rubber, so the oil rubber migration effect may be irrelevant due to the material.
ah...but it's a good thing the hoses are cheap so that replacement is not so painful on the pocket book. I'm sure DCX kept all these issues and more in mind when putting this engine system together using "rubber" hoses for the CRD intercooler intake.
And note that the report in the URL does not mention natural rubber (from a rubber tree). Nitrile and others(aka synthetic rubbers) were discussed. Urethane is a polyether and Dupont's teflon(r)is nothing more than a ubiquitous class of PolyTetraFluoroEthylene--both in the "synthetic rubber/plastics" class with drastically different properties and uses.
I am not sure the intercooler hoses are not good enough. Mine are still okay.
Sherlock Holmes also weighed in on this issues as follows:
"After eliminating the impossible, whatever remains, no matter how improbable, is the truth"
Oh and I got pissed today i read a consumer report that said that the CRD should be avoided because it was noisy, slow, and got poor mileage. 18 mpg is the number they quoted. I am Averaging 25 mpg.
Caribou1 says his intercooler hose weeps. His noted observations deserve unguarded recognition considering the calibre of his input on a weekly basis and the fact that he's willing to admit when he's wrong.
Your intercooler hose doesn't weep. Good. His weeps. Good. Therefore, the intercooler hose on the CRD has the propensity to weep in response to some sort of stimuli according to Caribou1. If he sends an update saying he spotted a different issue as the cause, then I'm sure he'll note the source of his discrepancy as he has done admirably in the past.

I discovered the strangest thing in relation to the shudder I've experienced in the transmission. You won't believe it, but I decided to pull the pan off the 545RFE transmission just for kicks. Lo and behold, I found a copy of the book, "The Divinci Code" lodged firmly up against the south end of the front pump! I swear it happened...really. When I removed it, and replaced the pan, I started up the CRD and it literally began flying! My gas mileage is north of 100 mpg, now, and the laws of physics and reason are all but unnecessary! And since I write it, unfortunately, without any evidence--camera footage, witnesses, documents, pictures--it really must be true!
So, for all of you folks out there who have been speaking about, teaching on, and designing the ever-improving mechanisms within transmissions, engines, and automobiles using historically empirical evidence who say this is impossible: this problem really was easily solved by my removing that ATF-soaked treasure trove of wisdom, insight, and verifiable fact. What's important to remember is that things that are "right" or "work" for me and my CRD, have zero bearing on anyone else's experience, perception of reality, or general common sense. Hail to the avarice-ravaged relativists, and go my flying CRD!

...oh, and I've posted my email addy in the alotted Edmunds profile, so anyone: feel free to bird-walk with me via that outlet.
My engine light popped with @10,000 miles on my CRD and I took it in along with an oil change. Interesting experience at the dealership.
The service manager writing up my service paperwork did three circles around my car. Why? Never saw a diesel or something?
He's a bit perturbed, I had the oil changed at a different dealership (it was closer to my home). Then says the oil change will cost more, synthetic oil.
He does another loop around my libby, then walks over to the parts dept. He comes back to my libby with two other employees and open the hood (duh, yup...it's a diesel). The have a little huddle for a couple minutes and then separate (first diesel repair?).
They get to work on it the next day. The service manager calls me to pick it up. He's happy to tell me the oil's changed and the tires rotated...then sneaks in that they have to order the EGR and "will call or mail me" to bring it back when the part arrives. :confuse:
Recall, we were originally talking about Farout's hose on a low mileage CRD when we decided to take a ride on the space shuttle. It is quite possible that the intercooler hoses on US CRDs are different material(s) and quality than what is on Caribou1's CRD. US hoses are lined with a different material than the outside rubber that you acknowledge but do not attach much benefit to.
You mentioned high temperature, pressure and solvents. We are talking about 23 lbs of pressure max, maybe 200F and boundary oil/fuel. Otherwise it's just hot air.
Now, I believe!
I think I would be looking for a different service center than the one you are with now. I had kind of the same thing when I took mine to the local dealership last August. I'm lucky because the town I work in also has a jeep dealer and they know how to work on them and treat the customer. The first dealer I went to and had problems with didn't like it when I knew more about the vehicle than they did. The service writer throw my keys at me. I told him a few fine words and out I went. Never to return to them again.
