Diesel ccv mod



For those who are interested, someone experimenting on the 3.0
Not sure if his motor is the baseline for what's out there in terms of sludge buildup

Great video, if a little long winded.

Re: Diesel ccv mod

Metal pitting turbo fans? How long can you expect the turbo to last with this going on?
Is this something common to all JGC Ecodiesels?

Re: Diesel ccv mod

I wouldn't get too concerned. The engine will likely outlast the rest of the vehicle.

Re: Diesel ccv mod

Here is the associated discussion thread regarding this mod on the RAM1500DIESEL forum. There are many there that hold "2012 Summit's" view that there really is no major concern. Interesting reading...

Re: Diesel ccv mod

Shawn (the guy who made the video) averages something like 120,000 miles per year and allows his truck to idle over 6 hours per day.

Not to mention that the Ecodiesel already has a highly efficient centrifugal air/oil separator.

The counterpoint is the several threads on this very forum where those who have installed catch cans on their WK2 EcoDiesels have immediately started collecting oil (and here Zybane noted his Provent collected 4 oz in 2k miles).

That's even before getting into the pics of coked-up turbos on other vehicle platforms that use EGR without catch cans.

Is this a problem if you're dumping the vehicle during the manufacturer warranty? No.
Is this a problem if you're hoping to make your vehicle last 12+ years? Well, how much does it cost to remediate a coked turbo vs how much does a catch can cost to install?

Re: Diesel ccv mod

Wondering if this is an FCA diesel design issue or are other manufacturers experiencing the same problem?

You need to take into consideration that the installation of the catch can modifies the built in oil separation system, therefor the aftermarket catch can results aren't very scientific.

Care to elaborate? The built-in separator is still part of the loop on most catch-can installation configurations. The only modification expected from the engine's perspective (aside from reduced oil in the PCV return) would be a slight loss of pressure. We know that the pressure is monitored by the ECM, so the drop cannot be excessive without a code being thrown.

I agree that it would be ideal if we had a systematic review of the carbon buildup on the intake and turbo on this engine after a decade of service plus hundreds of thousands of miles. Unfortunately, we still need to wait many years for that data.

Let me put it this way: if in 2023 we find out that these EcoDiesel intakes & turbos are still clean thanks to the built-in oil separator alone, I still won't think the people who installed catch cans were suffering from paranoid delusions for trying to protect against buildup. If we find out the turbo is coked because the built-in separator is inadequate, then spending $200 on a catch can will seem like a bargain in retrospect.

Sorry, I can't elaborate other than what you stated about a reduction in pressure. Perhaps at factory designed pressures, the built in separator is more effective. I don't really know.

I originally posted "I" wouldn't be too concerned. Everybody is entitled to their own opinion and if installing a catch can makes you happy, you could consider installing one. It very well may eliminate problems down the road.

The significant drawback to installing a catch can on our platform is that there is no drop-in kit. Every installation so far has been different, and often includes making a custom bracket. That's before getting to hoses, hose routing, and thrown codes due to excessive pressure drop (as seen in the OP's video). Furthermore, watching that video I was struck by how much space there is under the Ram 1500 hood compared to our Jeeps.

I'm leaning toward replicating Zybane's installation of a Provent 200, but it's anything but simple.
