No catch can on mine....simply a drain. I've driven over 1000 miles now and since installing it and so far I have not seen a single drop of oil come out. The inside of the pipe at the bottom is oily to feel but not really moist. Our pavement on the driveway is clean. You DO see some vapor at times. I can't say that everyone will experience the same thing. My total miles is around 55,000. I do know that I had plenty of oil inside of my swirl motor that came from the CCV before I made this mod.

This is a real cheap fix especially when compared to the cost of changing a swirl motor. The elbow was $1.19 I think, and the clamps were $.69 each.
I chose to use silicone hose at $17.xx per foot, but you could use heater hose that is way cheaper. The expansion plug was about $3.95 I think.
That's it. I also used a couple of cheap wire ties.

Not to rain on the parade but dont you need intake vacuum on that port to keep the upper crankcase at mostly negative pressure to help with ring sealing and combustion chamber contamination??

If you really feel the need to do this mod then it should be done with a proper catch can **inline** with the turbo intake tube and the engine crankcase ventilation port.

The proper ones dont have those silly K&n filters on top. they are a sealed unit.

Closed crankcase ventilation (CCV) is something that has only come about in the past 10 years in diesel applications in response to EPA regulation on *all* emitted gases, including fuel vapor, tailpipe, and crankcase. The crankcase ventilation in particular has high hydrocarbon content, partially from oil vapor but especially due to evaporating fuel from the oil as a result of in-cylinder dosing strategies for DPF regeneration. Thus, to reduce the total combined HC emissions, they figure it's easy enough to capture and route back into engine.

So to answer your question, no, CCV is not necessary for functionality or longevity of a diesel engine. It's merely an emissions strategy by the OEM's due to increasing regulation of light duty diesels.

Same conditions for me. I've put about 15k miles on my CRD since I installed my 1st version of the EHM I adapted from all the KJ CRDs. After about 10k miles of use, I removed it and cut open the hoses to see if they were dissolving since it wasn't oil rated hose. Other than smelling of burnt oil and being very slightly sticky, I found no real issues. I plan to replace the hoses once a year at a cost of about $20. I currently have about 5k miles on what I've called my "EHM Version 2.0". I have a thread called "EHM Version 2.0" with a Photobucket pictorial if anyone's interested. Similar to Chirpz's but it's just pics, no instructions.

I've experienced no drips or spray beneath the vehicle. At startup, there is no smell or visible "smoke". Once up to operating temperature, there is a decent amount of "smoke" when sitting at a stop that flows from beneath the vehicle. It's color is somewhere between "steam" and white "smoke". It smells pretty strong but is only detectable outside the vehicle.

I installed a Racor 4500 at 1,500 miles but it kept allowing some of the blowby to get into the intake. After wrestling with it for a year, a buddy of mine who has a KJ CRD suggested adapting the well known EHM for my CRD. I gave up on the Racor at 7,500 miles and set up the EHM. Currently at 22,500 miles with no issues.

If after 15K miles there isnt much damage to hoses, why change them so often? We put about 10K miles per year so we were thinking of 3 years or more between replacement. The only thing that I can see that would be a problem is if the hose some how clogged, who cares if it gets sticky or oily on the inside? My local NAPA wanted nearly $30 for the hose I used, which hoses are you using that cost $20? Do you have a part number? Thanks!

I am swamped tomorrow, but could get one for you Saturday morning if they still have them in stock at the local hardware store.
You would need send me your mailing address via private email.
I can bill your for part plus shipping via paypal. I'm in a small town in Washington state.

Pretty sure I've seen these plugs in your basic Home Hardware or Home Depot's here in Canada. It would likely be in the plumbing section.

I checked both places, and did not see the right size.. The one Home Depot I went to was a 'smaller' one.. maybe I will try the other
