EcoDiesel Catch Can

[harrish24]

What is everyone running for a catch can? I would ideally like the Ecodiesels of Canada catch can, as I have their delete, engine, and trans tune. The price, tariffs, I just can’t justify it right now.
I don’t want to throw one on and get codes and limp modes, so hence my question, what other options are there that are tried and safe?

What do you want a catch can for? The tuning you have turns that stuff off. I guess they can still open under the right/wrong circumstance though.

A tune turning functions off doesn't prevent blow by. A catch can will help monitor the health of my engine as well as extend its life by preventing oil consumption. Just looking for alternatives that don't cause the crankcase pressure code.

There was a guy a while back who blew his engine. The whole storyline was a complete shit show, but we're fairly confident the blown engine was the result of not emptying his catch can before he went rock crawling. If I remember correctly, it was his second engine.

Not saying it'll happen to you, but don't be that guy.

Catch cans for diesels are dumb. Tried and true method that has worked forever is a tube off the top end somewhere that dangles down and vents to atmosphere.

I installed the Mishimoto catch can. Nicely built but expensive. Works fine with no error messages.

That will throw error codes on an ecodiesel.
Open tube works fine on my Cummins ISX 650 in my 2009 motorhome. 922 cubic inch engine.

I have that on my 22’ F250 but it won’t work on the EcoDiesel motors.

Thank you, finally someone who gets it

What codes? You've seen this? Or seen discussions on the topic? Got any links to share?

I'm trying to imagine the type of sensor and the particular placement it would take for this to be true. The engine needs to vent crank case pressure. Instead of regurgitating it back into the intake that piece is blocked off and it vents to atmosphere instead. And requires zero maintenance for the rest of it's days.

Looks like there are 2 sensors one at the point where the CCV enters the intake tract and one where the crank case breather tube leaves the engine. Seems like the one at the intake should see a vacuum and the one leaving the engine should be pressure. So if you disconnect either it'll throw a code. I guess I need to take my intake apart and see if there is even any evidence of oil in the intake. No sense in worrying about the CCV if there isn't.

Just watched a video where a guy says one of the sensors is a flowmeter.

I have been running eoc's catch can for about 5k miles. no check engine lights yet

from where?

from where?

First let me start by saying all or at least most of the emissions requirements are retarded. At least in so far as they can/could be good for the environment and also not be so detrimental to our engines. A happier middle ground could be achieved.

Having said that at this point from my understanding I'm not sure that anything at all needs to be done with the CCV side of things. The EGR is a killer for sure, but the crank case vent? Enhhhh, I don't think it's going to cause much damage if any. The EGR if left to run wild can cause some serious issues. All of the crud needs to be cleaned out maybe every 75,000 miles. Either that or a guy should be borescoping and making sure it isn't getting outta hand.

Where to pull off the top end? Back up a second. After seeing that there are 2 sensors of some sort or another I agree with these guys that say it'll cause issues if you leave them non functional. They'd have to be defeated via tuning, or somehow physically fooled in some way. But like I said I don't think the CCV is worth the effort.

But to answer the question to an extent just somewhere off the valve covers. Just look at how it was done on the 5.9L cummins. Actually probably better look at a 7.3L Powerstroke (v design vs inline) probably get a better idea of how it worked.

How much gunk is accumulating in your catch can? Now that you have seen the can working, would you recommend it?
