I took the hose off yesterday and of course the inside was coated with oil. Also the FCV was well lubracated. I droped my nut driver and when I got it I happened to look up and what did I see? Oil comming out of the tube going to the EGR valve. Now that should not be there. What will the excuse be this time?

DCX's reply will be, "That's normal"

You watch, this situation will eventually become the killer of this engine.

I wonder how many engine this has "killed" on the other side of the pond. Haven't they had these for years? Are they running CCVs? I'd like the hear from them. How many miles and such.

Ehmehm..EHM! sorry i just had to clear my throat. :lol:

As far as I know a provent will prevent this..and will let you know if your turbo seals are leaking.

Yea but DCX will say that the Provent or EHM are reasons to void the warr.

They've used the same CCV setup on the R2516/R2816 engines since their inception in 2002.

Not exactly true. I had a long discussion concerning the Provent with the DCX reps last Spring. They are well aware of what a Provent is and know it's used on VM engines in other applications. As long as the Provent is installed per instructions and no factory equipment is removed/disconnected there are no warrranty issues. She inspected the installation (and took notes) because she was surprised I found a place to put it.

What they did have a problem with was the EHM because it was removing/disconnecting a required emissions device.

Air cops are everywhere out here. Glad I don't live on the front range. They have sniffers that can detect a fart.

I work with a fleet of over 200 Detroit Diesel Series 50 "Clean diesel" engines with a virtually identical emissions system. Not exactly the same because the crankcase vent is open (like an EHM) and has the EGR located on the other side of the engine near the VGT (like the European spec).

These engines also suck oil throught the CAC (turbo seals leaking), does the whole plugged intake manifold thing like the TDI's, and then pass it through the engine where it cokes the VGT and/or causes excessive carbon build-up. We go through VGT's and EGR's by the case and frequently have close to 1/3 of the over 200 coaches down for engine problems, usually VGT or EGR related. Not uncommon to tow 5 or 6 coaches per day for locked-up VGT/EGR (yes, when you loose one all you get is coal black smoke/no power and it can't be driven). We are now replacing engines (3 yr old coaches) for soot scouring ruining the upper engines because sucking recirculated diesel soot through an engine is about the same as running without an air filter.....And that harmless motor oil in your air intake, it make more soot to compound the problem. Have watched this game played too many times to accept this line of BS from DCX.

I just got finished changing out the fuel filter. It went off without a hitch. I was able to do it from above. I sqeaked a pivotting strap wrench next to the filter and got it around the bottom. I went in from the brake MC side. Anyway, I was cleaning and doing some general gawking, and noticed the intercooler hose was sweating. All under the mesh stuff was oil on the outside of the hose. I guess it is saturated and coming out. I go down to the dealer to have em look at it today. I am hoping for the replacement hose.

What, you've got a problem! I spoke to a young woman with a 05 CRD this afternoon. One morning her crd would not start. It was 2 quarts low on oil and it was in the cylinders :!:

The dealer then replaced the turbo. That's one of the places the oil is coming from and seeping from your hose. RFCRD can tell you all about it. She commutes about 60 miles one way so the tc had not failed and they got the F37 done.

Oh no, and on a 06 CRD!

WTF are you talking about? The hose is a wear item that is made of rubber that can't handle oil saturation. It is not specific to the '06 or any other year. It's not a perfect world son. Sorry to disappoint you.

Not a problem. Just getting a new hose good for another 23,000 trouble free miles. :lol:

Yes it is a problem. All that oil is supposed to stay in the crankcase, it shouldnt be going through your intake. If there was enough oil to soak through the hose, how much do you suppose is sitting in your intercooler?

Not much, but since I haven't crawled in there with a measuring stick, (I know of a coupls on here that will ask) Can't say for sure. I have never had to add oil. In fact it has always stayed right where it is supposed to be. I know that the design of this system isn't perfect and that it allows some oil vapor to circulate. It is this oil in it's atomized state, that is been forced out through the pores of the rubber CAC hose when the turbo system is pressurized. Now some have had turbo seals leaking. They may all leak when it is said and done, but since I have no oil missing at the present, I'm good. I don't worry about what MAY happen tomorrow like some. If it does and if it trashes the Jeep, No worries. I'll just go buy something else. No biggy.

That is exactly what they said.
