6.7 Crank Case Filter Delete

[cerberusiam]

Deleting is the CCV filter is pretty common once you take the CAC and intake apart and find out what a mess it makes. The design is pushing oil vapor into the intake side of the turbo, it isn't hard to figure out what a mess that can make. No matter how good the filter it will NOT remove all the oil from normal crank case outputs, all that will eventually be squeezed out in the compressor and CAC and then dumped into the intake fouling the sensors and the grid heater.

You really ask WHY? How about so there isn't raw oil building up on a grid heater that gets hot enough to fire it off, fouling some expensive sensors, and coating the CAC internally. It was and is a stupid cheap system to meet emissions.

Thats all well and good, but is it a issue that occurs with any frequency ?

We can go back to under coating the truck like I did when I got rid of the puke bottle on my 2001.5 and extended the hose down to my steering box stabilizer.

It is happening all the time from the time the engine starts running. There is no valve or control on it, the harder you work the truck the more blow by is generated and the more oil vapor is purged thru the turbo inlet. At what point does the filter become a problem? There is no info on how much oil vapor is generated by engine load or boost, it is just a given it is more. The question becomes how much more crap do you want to stuff into the intake with the problematic heater grid, and, how much will it take to reduce CAC efficiency by a factor?

It is not an IF, it is a WHEN that it becomes a problem. All you have to do is look at the intake after 50k miles and see what is going on. Newer trucks with DEF are going to have less EGR but same amount of vapor. The point is it is dead easy to add a catch can to collect any escaped oil and NOT run it back thru the intake. This is common practice in gas engines to clean up the intake tract, works perfectly for diesels.

Link to the kit that does not create a warranty issue with FCA and is OK with EPA?

. It was and is a stupid cheap system to meet emissions.

Especially when you see the size of the CCV filters used in anything but a pickup.

The QSB's 6.7 I run at work have a CCV filter that must be 12" diameter by as much tall. And they still have an oily vapor on the "clean" side.

I'm pretty sure he's not too concerned about warranty on a 12

That was for cerberusiam.

Any and all of them. Neither one of those entities really care one way or another about a catch can in conjunction with or instead of the the existing stuff. EPA is not going to come and get you because you added a catch can, FCA is not going to deny warranty due to a catch can. FCA is going to deny warranty for a myriad of reasons that have nothing do with anything particular, that is how they work. If it really is that big of a deal take it off before emissions testing or warranty examination, some of these systems are dead simple to install\remove. ALL of them will provide a better degree of oil vapor cleaning.

If your reason is to save the turbo! Are you going to delete the EGR system all together such as the cooler and crossover tube to the air horn? Are you going to change out the turbo to remove the exhaust brake feature since very, very dirty exhaust gas is driving the turbo!

Not sure you have EVER sounded more childish or ridiculous, and that is saying a lot. Shame on you for responding like that, and, being so narrow minded.

this thread is almost as painful as watching the " alphabet news . " i appreciate what the original poster did, and watched his video. i appreciate his time. all i did was ask, in a kind way, why? now some guy named killer 223 wants to knock out my teeth. well , back to the personal insults. cheers comrades!

People take written word out of context all the time. It’s easy to do. It hard to interpret meaning sometimes. Was he being serious? Was he being sarcastic? It’s all in how you read into a post sometimes that makes it come across bad or weird. Other times it’s painfully obvious someone was showing their butt.

It’s the internet folks. Don’t get too worried about something you read on the internet. Lots and lots of misinformation and even more opinions. I’d like to think the TDR is above this, this is a great site, but it’s not... Please take that into consideration before posting a rebuttal when it could all go sideways for nothing.

I was just asking why, nothing inferred.

In my working life I was involved in rolling computers bank wide to all employee's and providing bank applications and email in the mid 1980's. We were the first large corporate customer of Apple Macintosh Computers, linking them all to the mainframe computer system. We had training sessions for them on applications and email. With email it was noted as being flat and single dimensional, and staff was warned about how you presented things via email. My DW says that when I post something on her facebook page for her I use to many words. Well old ingrained training is hard to ignore.

Like you my DW say's I am to wordy when I respond to a question! She will not even let me post anything on her Facebook account!

Friends,

I haven't bought into gutting the CCV filter, but I do like the oil catch can option. I have them for both of my gassers (wife's 2019 Ram 1500 5.7L and 2014 Jeep Wrangler). After reading this thread, it makes sense to me to add on to my 2017 Ram 5500. Already got the oil catch can from Amazon, gotta get a couple of 90' barb fittings to plumb it in.

If y'all remember, the 2nd gens had an oil catch bottle on the front of the motor that didn't hold much and frequently overflowed. I rmoved mine and ran a long heater hose behind the cab... it still had vapors that you could smell if you didn't run it far.

OP, thanks for posting.

Cheers, Ron

post pictures of your install. I was thinking of doing the same thing on my 18.

In Northern climates it is not wise to run it very far back, as the moisture in the blow by freezes and can build up to the point of blocking the hose, and then you start blowing seals.

Sno, sorry not more clear on that 02 truck...eliminated the oil catch bottle and had fluid drain on ground... this was before my shop and truck didn't fit under previous carport. Most of it disbursed, I'm pretty sure, under speed. That truck smoked like a freight train too. Now, I'm a little more environmentally conscious.

The one I'm installing in my 5500 will go in the pax side corner of the firewall, easy to access, not too hot, and plenty warm as this is the same side as the turbo. I'll add checking it to my monthly fluid checks and inspection checklist.

Cheers, Ron
