Dave send me a link to the Endura you mentioned, I will also be looking at some Gulfstream units tomorror atv the same place.

One thing about the Sprinter is it small enough to be easy to drive and can be driven daily if needed, but the thing I don't like for something that small is it is too tall for the garage. I would have to put up one of those el cheapo carports, to give it some protection when sitting at home.

Ok I just found the Endura, sure looks nice. How much was the one you looked at there in Texas? Maybe we should compare notes aftter I come back from St Louis.

Last year, before Motorweek, we sat in the sprinter(sat in a freightliner chassis as soon as they had them in the lot in Irving Tx) at McClains RV in Denton, Tx. There was no tilt wheel and the full msrp was like $78K. At the recent motor home show it was not hard to get 25 - 33% off depending on the models. The Duramax/Allison - saw one at McClains and saw one at the show - I vaguely remember one build was of inferior quality. The FRED Crescendo by gulfstream was shown at the dallas rv show by Professional Sales RV of Colleyville, Tx ~ 75k , one of two was immediately bought upon the show opening. It was one of the family members that loved driving the fred to the show and it was also one of his relatives at their store who still liked pushers for maintenance. I remember seeing a plastic end caps CAC like the CRD on one model but fred has a metal CAC. FRED by freightliner has cummins/allison and vgt and 15000 mile oil changes. Sorry I can't be of more help. I'm sure some rv'ers can be of more help.

I suppose I should jump in here and ask for a spot in line for the OldNavy CCV ....

Where 'bouts in Missouri is your hometown, OldNavy? I've got a lot of family around southwest Missouri in Hurly, Crane, Republic ....

Guys,
Sorry to jump in so late on this long thread...
I installed a Provent at 16500kms (10,000miles) about two and half months ago. I now have 20,000kms on the clock and still are getting oil in both CAC hoses. I had cleaned both hoses thoroughly, the air valve and the intake bend of all the goo (but not the intercooler) once I installed the Provent. The Provent is collecting oil and the filter is beginning to turn black at the bottom section. I have used Shell fully synthetic oil since the 5000kms service. I have pulled every thing apart in the CAC hose network except the turbo and intercooler. The turbo has no end or side float and the compressor section looks and feels clean and dry. I have had a new air filter, (which is dry), since 16000kms.
Any ideas where the oil is coming from? Could it be I have a heap of oil stuck in the intercooler and it is still being stirred up?
Any help would be appreciated.

How many miles since you changed your air filter? Should be 12,500 miles max or the pressure differential will start pulling oil into the system through the turbo seals. To compare, Ford Powerstroke states 10,000 miles max before air filter change.

Roughly 4000kms or 2500 miles. Filter is good.

MACKJ:
This situation is a big dissappointment with my CRD. I can already see that hose cleaning will be part of the regular oil change ritual.

I have been watching the CAC oiling closely long before installing the Provent. Have also seen the effects of wet/constricted air filter on the system. The Provent is working and the air filter is clean & dry on mine but still have some oil getting past the turbo seals. The amount of oil is insignificant when compared to what it was sucking before modifying the airbox to stop the water. I last cleaned the turbo to intercooler hose @ 1000 miles ago and already have oiling from the turbo discharge to the first bend in the hose. After the first bend, it's clean & dry. Have a gut hunch it's related to the 0W40 oil that the dealer installed to run an oil consumption test. Once the testing is through, will switch back to Rotella 5W40.

Was told by a local oil supplier that the synthetic 0W40 and even the 5W40 will get past the turbo seals. He recommended 15W40 CI-4+ rated non-synthetic to stop it. Don't know if it's a myth or the truth??? If it weren't for the warranty stipulation for the synthetic products, I would be running standard Rotella or Delo 15W40. If this is true, this would not be the first turbo diesel I've seen that can't hold lighter viscosity oils.

Seen the same thing on mine, Provent outlet nice and clean, but still getting oil from the turbo in the inlet hose, with Rotella 5W40.

About 1000 miles ago, I put in Amsoil 15W40 synthetic to see if any effect on MPG and this same problem. EGR replacement and bad glow plug have sort of intervened.

Once the GP issue is resolved, I'll check and clean the hoses again, go another 2 grand and see how it looks at the next oil change.

Allowing for the EGR and GP, no detrimental effect on MPG that I've seen running 15W40 synthetic.

This sounds like it's starting to pan out to be something major in that it's finally being discovered. I had emailed VM a long time ago, and it took them about six weeks to reply with an official response. Basically, "follow the Jeep Liberty user manual recommendations" for type and grade of oil.

I wonder what the user manual states to use in the European version of the 2.8L CRD Liberty (Cherokee). I hope someone can answer that.

Guys just remember that if you are using a Group IV full synthetic oil (Rotella T synthetic is Group III) it starts off as and is always 40w oil with additive package to give it flow rates of 0w or 5w (or what ever) but as oil heats up it is 40 wt oil. Group I, II, III oils made from conventional oil stock starts as the low number, which is the oppsite of Group IV oils. So Rotella T 5w-40 Group III so called synthetic oil starts out with a base stoke of 5w oil.

That said there may be two oil problems at work here, the non Group IV oils may be to thin and is too easy sucked passed the seals, and the Group IV oils could be too slick and gets pulled past. I have been thinking about going to a 15w-40 Group III or Group IV oil to see if this help with oil in CAC. What bugs me here is never had this problem on the VW diesels, so I am thinking there is a third factor with the air box that possiably drawing enough air durring high moisture driving.

Guys,
Thanks for the feedback. I will investigate different viscosity oils. I would prefer to remain with synthetics.
My owner's manual recommends 10W-40 to spec ACEA B3 or B4. This maybe the same as the Euro spec.

Old Navy I guess I am going to have to take a photo of my CAC hose,
5000 miles, and only one dry string of oil. Nothing else there. European
5-40 and nothing is coming yet. Going to modify the airbox with the
snorkel and gas bottom box.

RFCRD · **Posted:** Tue Aug 01, 2006 11:09 pm

One thing I should clarify is that I have to pull the CAC hose at the turbo end to find the oil. Pull it at the intercooler end and it's completely clean. Guess it's a question of how much oil is reasonable??? I can live with some if it doesn't throw enough to make it to the intercooler. At least I know the there is good oil flow around the turbo bearings. Still concerned that the oil accumulation loads around the hose connection and sweats/leeches out around the hose clamp making a mess. Also likely it will eventually soften the hose end making it prone to failure.

My turbo side hose finally dried up at the CAC end of hose after doing EHM. I never did have much if any oil in the other hose, but turbo side hose was wet and slick from oil until after I did the EHM and stopped the oil from going into the system.

Keep in mind that I was still cleaning-up after some bad oil drafting over the Spring. Mine seemed to have dried-up too after the airbox mod, infact the oil residue turned tacky, almost like tar. Last week I got the primary hose squeeky clean with some B100 and a dishwashing brush, then flushed it with ether. Was bright red and felt very porus inside when I got done. Afterwards I ran the snot out of it for @ 1000 miles and noticed the mild oiling. Starting to wonder if the tar residue seals the inside of the hose and keeps them from sweating oil???

From what I've seen, the Amsoil 15W40 hasn't helped as far as the amount getting drawn out thru the CCV. I put a new section of clear nylabraid hose between the hockey puck and the inlet of the Provent when I changed oil. After 1000 miles, it's got black oil all thru it.

However, it does seem that the Provent is more effective at filtering the Amsoil 15W40 than the 5W40 Rotella. With the 5W40, until the filter got loaded up with oil after 2000 miles or so, there was a small amount of oil mist still getting thru - it stained the inside of the nylabraid a light brown, and there was a light coating of what looked like light machine oil in the fitting connecting to the stock CCV hose. 5W40 with all the crud filtered out?

Besides the inlet hose, at the same time I replaced the outlet hose and popped in a fresh filter in the Provent. After 1000 miles, the outlet hose still looks brand new, and the fitting at the stock CCV hose is still clean.

When I mentioned that I was still finding oil at the turbo end, prior to switching to Amsoil, I was getting the "dried black snot" variety, not wet/slick/liquid. Haven't seen anything in the hoses you could really call "liquid" since I started running the Provent, just the black snot/tar.

I have the chance to get a Racor filter. I realize that the ccv of choice is the ProVent, but has anyone installed the the Racor, and if so, what were your experiences.

I think you are going thru uncharted territory. The Racor is a great unit but very pricey. Let us know how the install goes and take pictures and post.

Good luck.
