Jesse...sorry thought this can had some filter element in it. Are pressure difficulties the only reason why wouldn't you want a can with some type stainless steel mesh and/or screening mechanism to act like a maze to collect and condense the oil vapor? Dave

Re: oil catch can

There is a simple baffle, but the design I am waiting to receive is the least restrictive for our setup. After it is installed and secured in the engine bay I'll post a pic and also if it causes the computer to throw a code. I won't leave you guys hanging but the guy making the can is swamped with ordered for custom CC's. He has been keeping in contact regarding my spot in line.

oil catch can

I modified the original design of intake and outlet ports to allow the use of the stock hose from crank case to intake. Similar to Futuresystems setup. Now I only need to run a hose from crank case to can and plug the stock hose that runs from intake into the outlet of the can.

Were you able to get this installed? I really like the idea of a can created with inlet for the stock hose diameters.

Re: oil catch can

Subscribed. Just curious what oil are you guys using that are seeing a lot of blow-by?

The problem isn't the oil. The problem is that the EPA mandates that the engine route exhaust back into the intake (PCV).

Regardless, it's not like EcoDiesel owners have real choices in oil selection. You can either use Pennzoil Ultra Euro L 5W-30 or you can use Mobil 1 ESP 5W-30. Practically speaking, that's the extent of your options in North America in Feb 2015, presuming you like your warranty. I've used both now.

I'm still waiting to see the killer, drop-in catch can for our platform. The guys who have done it so far have done a great job, but it seems like they had to do their own engineering rather than install a kit. For example, the lack of premade brackets is an issue for me... fabbing a bracket isn't within my current capability.

EPA is a problem no doubt in my mind, probably 90% of it or more. I just asked about the oil because there are people who might be using regular Mobil 1, or Rotella for example to save a few $$. A low NOACK oil is what you want in that application and the two I mentioned aren't good for that engine. Low NOACK oil can handle heat and is less likely to vaporize and go through the PCV system. I'm not saying that is 100% of the problem, but it could be contributing slightly for people using the wrong oil. As far as I know the only two oil choices easily available are the two oils you mentioned. That leads me to believe a large % of people could be using the wrong oil making things worse.

From what I've read and heard installing a catch can and not getting a CEL can be a royal PITA, but I think it is a necessity for this engine. It would be awesome to get a drop in unit that won't trip the CEL out of a box.

That's pretty scary and a prime candidate for a catch can. You'd hope they factory filled it with the right oil. An analysis of the oil in the sump would be very interesting.

Re: oil catch can

Update.

I continue to get about a good teaspoon of oil per thousand kilometres in my catch can, definitely stopping a very worthwhile amount of oil. That has to be a good thing, rather than that oil going through turbo/inter cooler and into the manifold.
Of course, how much is getting past the catch can, I do not know.

PS pulled my EGR pipe off the other day, (it's just two bolts at each end), very easy, and don't like what I see- a lot of gooey black crud in the pipe, and inlet manifold.
I'd love to block the EGR but suspect it would immediately throw fault codes and possibly cause other problems, so at this stage that's a no go.
