6.7 Crank Case Filter Delete

[BigPapa]

the 2nd Gen 24-Valves had an oil catch bottle on the front of the motor that didn't hold much and frequently overflowed.

Fixed it for you.

On my "Old Faithful" 99 2500 I just lengthened the tube from the CC vent on the timing gear cover and extended down to just in front of the front differential and believe it or not , my diff has never got any rust on it in over 20 years. I also found out that if you only fill the oil up to half between add and full, my truck would puke very little oil vapors, but if you filled it to full, it would puke out the top quart in less than 400 miles and mostly stop at the 1 quart down point and stay there for about 2500 miles and I would add enough oil to get to half way add to full. I still only add 2 quarts between oil changes 8k to 10K miles /once a year. The 99 is my daily driver/work truck at 240K and still needs only a little bit TLC maint from time to time.

Friends,

I did it. I chose to mount the catch can to an L bracket attached to the support arm for the cooling shroud. I reused the existing rubber crossover hose coming off the engine sensor, used a 3/4" to 1/2" reducer barb fitting, and 1/2" hose to fitting on oil catch can. support arm for the shroud. I cut about 3" piece of 3/4" hose and a 1" x 1" barb fitting coming off turbo to front of engine, then 3/4" to 1/2" barb reducer, then 1/2 hose to the oil catch can.

Just a point... when I removed the rubber crossover hose connecting an engine sensor to the turbo had a pretty good bit of oil on it and I only have 20K miles on my Ram 5500.

Parts on hand and purchased. I used a 3"x3" L bracket attached to support rod with HD hose clamp.

And the finished shots.

And

Easy project.

Very clean job Ron! May look into doing this as well.

 

[endoscott]

Thanks for posting pics. I just changed my CCV filter and there was a pretty good oil coating on inside of housing. Might do a catch can.Where did you get the kit? Seems like Genos garage should carry a kit like this.

 

[HPSimpson]

Great idea Ron, my '19 Ram there is ZERO room to mount something that big in the engine compartment.

 

[Wiredawg]

Friends, here's the one I purchased

I picked this based upon 4.5 out of 5 star rating and capacity 400ml. This one only plumbs to a closed system. On my former 09 4500, I had one that plugged the turbo and from the engine vented through a filter attached to the lid. That one released oil fumes into the cab, so I removed it.

Homer, if no room in the engine bay, maybe it's possible to mount underneath the truck.

I'll try to drive the 5500 more, check mileage and check dipstick. Guy on the Internet had maybe an ounce after driving 1600 or so miles.

Cheers, Ron

Friends,
Just thought I would mention one little detail... you'll notice in the pics I posted I did not install heater hose clamps on every fitting. The one inch 90' barbed fitting required putting fitting in a bench vise and using all my strength to get on using WD40 to lube it. The only way those are coming off is to cut them off.

Also as mentioned previously, instructions warn to empty weekly if freezing and hard freezes you should disconnect the oil catch can and put back to stock. Freezing not a problem down here in SW TX.

Cheers, Ron

Ron, I was going to mention that you now need to mark your calendar to drain the catch can on a schedule. I guess the company stated weekly?
That seems to me like a lot of oil being emptied ever week from the CCV system, 400ml is approximate 13.5 fluid ounces. So, I guess you will need to check your oil level at least once a month.

 

[lpennock]

Adding a catch can shouldn't impact oil usage. It was going back in the intake before, now it is just captured for dumping.

 

[Jim W]

But didn't Ron say this was a closed system so, the CCV air flow will still go back to the turbo. With the CCV filter in place I don't thing there is that much oil being pass to the turbo, is there?

Jim, they recommend checking weekly til you establish a baseline... I'm going to check it monthly along with other checklist items as this isn't a daily driver. I'm going to increase driving it as it is fun to drive and only slightly longer than a 3500 dually.

Also. I did not eliminate my CCV filter, only catching oil going through it, which based upon visual inspection of the OEM hose, is noticeble and eventually measurable. I'll post on 1 Sep versus 1 Aug with pics and mileage on oil captured.

Thanks for the thought.

Cheers, Ron

For you folks up Nawth who have real winter, it would not be hard to incorporate valves to bypass the catch can during freezing conditions. Mine would take about ten minutes to put back to stock, so also easy to swap back and forth.

Cheers, Ron

I better get me one of those to save my turbo and engine! 24,000 miles.

Just like mentioned, a lot of residue on mine for setting 4 or 5 days. I idled about an hour and a half yesterday and drove about 20 miles. After I get backhoe connected back on my tractor I'll check the can and see if any coating on it and if any I'll post pic.

EDIT: Happily not even any oil film... this is something that happens over a lot of time running engine and puttong miles on it. The YouTube I watched had what looked to be a couple tables spoons in the catch can after 1600+ miles and towing, and deleted CCV filter.

Cheers, Ron

The harder you work it the more you'll end up with in the can. I know Sag2 has had that puppy cross country with a camper in tow so it's good to see his looking so clean....even if it don't have 2 oil changes on it yet

It's R.Taylor not R.Tayler AND lighten up dude... Have some humor in life. Calling names and saying people need teeth knocked out is rather uncalled for. If you are even on this forum much you will see there is some creative humor / criticism often taken with a grain of salt... No Harm, No Foul. You on the other hand have worked yourself up and are angry with us.... But with a name like Killer I'd guess there's not much of a funny bone in your body.

I knew a 68lb midget that went by killer. I wonder if this is him.. You can get real mean and angry on the net because no one can see you !!! just my two cents.

You are welcome to come over and find out for yourself.

That said, I do think we need a sarcastic font. it's something i've been working on with Microsoft and the Linux community for a while now.

I don't like rude people, keyboard arse wipes need an education, most will pop off at the mouth on a keyboard and would never dare say that to someone's face, i'm not one of those guys. i'm all for teaching other peoples children how not to act and how to respect others. Something that is lost in today's population.

@Wiredawg. I was looking at your install pictures. If you have the room I would consider moving to the lower set of holes on the mounting bracket for the can. Ideally you want the hoses to the can to be running down hill so any oil that goes past the can and condenses on the hose will flow back to the can rather than flowing towards the turbo, especially after shutting off the engine. Just a suggestion.

We're thinking the same... I had to mentally study overnight to figure it out... It's slightly lower, but the real deal is its oil vapor (gas) exiting CCV filter so that's what's traveling through the hose, and I believe FWIW that is condensing along the way, even with turbo vacuum pulling it. So, if I lower it, I can't remove the bowl without unbolting it from the bracket. Still want to keep it simple and quick service item.

Here is what my FSM says about CCV System:

"DESCRIPTION

The CCV system contains the following components:

• Cylinder Head Cover Assembly (7)
• Breather Element (2)
• Breather Cover (1)
• Crankcase Pressure Sensor (3)
• Crankcase Differential Regulator (CDR) Valve; a part of the breather filter cover (1)

The cylinder head cover assembly (7) is made of a composite material. The cover has a recessed area for the breather element and passages for oil draining from the breather element, back to the crankcase. The breather element is serviced separately. The drain tubes have one-way check valves (4), (5) and (6) that prevent oil from being forced up the tubes by excessive crankcase pressure. The external fittings to the breather tube and breather drain tube are serviceable."

If anyone else does this on a daily driver, it will be easier to measure results.

Thank you for providing your suggestion.

Cheers, Ron
