PCV line / Oil Catch can
 
Could anyone confirm that this is the PCV recirc line in which to splice in an oil catch can? Look's like it's possibly the air pump from the crank case and going into the air intake line right before the turbo:

Would be a resource as I am sure many diesel owners want to get a oil catch.

Anybody know? I figure that line has to be it as it's really the only tube going into the air intake track just before the turbo..

I ordered this bad boy:

Provent 200 Oil Catch Can Diesel

From my research the ProVent 200 is the most efficient catch can out there at 90+% efficiency. Important for turbo diesels.

Hi Zybane, Yes that's the PCV recirc line, and fitting a catch can is a good idea on any turbo diesel with EGR

Ok cool, I will do a little write up of the install when the catch can comes in.

Here's some pick of where I installed mine (billet technology catch can), I'll be interested to see what you think of the provent

Nice! I was thinking the same spot. Do you remember what size tubing and fittings you used are?

Zybane, where are you going to route the oil drain line to?

I'd like to admit my ignorance here: I've had many diesels, but have never heard about adding a catch can. What's the benefit?

There's ton of stuff about it on the interwebs, but the quick and dirty is that the PCV ventilates the crankcase by sucking fumes, oil and particles and feeding them back to the intake manifold for the engine to burn it. The oil in that mess can have detrimental effect on turbo's like coating the intercooler with gunk and carbonizing on the turbo fins (oil coking). Catch cans filter the oil from the mix.

I will put an oil drain line right down by the engine oil drain a the bottom of the oil pan. That will allow me to drain it at every regular oil change.

What a Provent does is in fact remove oil out of that crankcase slurry/vapor coming out of the PCV valve as stated. It has mainly to do with the EGR as these EGR exhaust gasses have soot (particulates) and this soot mixes with the oily vapor now coming in as intake compressed air and 1) clogs the intake plentum 2) drives up EGTs 3) cokes up on the exhaust side of the turbo freezing the needing-to-move vanes and stuck vanes then create over boost 3) cokes up exhaust valves leading to premature wear... (there is more!).

It depends on how aggressive the EGR is set which probably is high as big brother government's EPA has these special standards for light diesel in the USA.
Proper thing to do is eliminate EGR but 1)voids warranty 2) stopping EGR will imbalance th rest of the exhaust system ( DPF, Regen, SCR ) and 3)is unlawful.

My experience with VM Motori (2.8L I4 in a Jeep KJ CRD) here in the USA has bore out some of these horrible symptoms. I had coked up vanes on a turbo rendering it useless. Other KJ CRD owners came up with SEGR so one can shut the EGR but reuse it when SEGR was disconnected. Of course this is for off road use only.

Back then (2005, 2006) ULSD was not even in existence. And sulfur is the main activist for soot formation. LSD and <1000PPM regular D2 was all suppliers had. Do not even think of using Red Dye Diesel(PPM is>5000). And biodiesel needs to be addressed(I will be checking the user's manual for initial recommendations).

My new WK2 Ecodiesel gets delivered Friday the 22nd and I am going to look to install Provent.

Keep an eye on the quality of fuel. ULSD ONLY! EPA rules and laws state emissions system must stay intact for 100,000 miles and States(like the diesel emission rule in California) are going to be checking especially DPF removal and SCR delete.

I think the only thing sold in the USA is ULSD eh?
