Catch Can on VM Diesel

I have a question for those that have installed catch cans on their VM Motori diesels. Do you actually catch any oil? If so, how much and how often?

The reason I ask is after reviewing service training manual that Milous uploaded in the premium member section, it documents a centrifugal oil separator device built into the crankcase ventilator system that routes cleaned air and allows oil to flow back into the crankcase.

The manual has a couple of diagrams that shows the centrifugal oil separator, baffles, and oil flow. Here is a quote from the manual:
"The 3.0-liter diesel engine uses a centrifugal oil separator to route crankcase gases to the intake manifold. The oil separator is attached to the left side intake camshaft. Crankcase gases flow through the front engine cover into the baffling machined into the front upper left engine cover. The vapors are routed to the fresh air inlet tube and liquid oil flows back down the baffles to the crankcase
So, if you have a catch can, does it actually catch any oil?

I would find it hard to believe that the relatively simple baffle system in an aftermarket catch can would catch more oil than the centrifugal system built into the engine.

-Eric

Re: Catch Can on VM Diesel

Whatever system is uses, doesn't work very well. I just installed my catch can (actual paper filter element) and just after one drive there was a good teaspoon of oil in there. Also, only 1,000 miles on the engine and already the air intake post PCV input was already slick with oil. Engine definitely needs a catch can to prevent gunk..

Re: Catch Can on VM Diesel

Any place I can find more information on where the catch can should be installed? I have about 750 miles on my truck and was hoping to take care of this as early as possible. I've had really bad experiences with VWs and intake clogging.

Re: Catch Can on VM Diesel

I'll add my vote to have Zybane show us how it is done. If this ProVent 200 is as large as people are insinuating it is going to be interesting to mount.

[EDIT] Thanks for the pics, Zybane: PCV line / Oil Catch can

Re: Catch Can on VM Diesel

I know that this is a bit off the Provent topic but I added a Billet Technology catch can to my 3.0l VM motor on the weekend.
I made a bracket from a piece of 100mm x 10mm aluminium bar, cut it with a jigsaw and cleaned it up.
I used the 2 x M6 tapped holes in the end of the head cover for the mounting point and tapped a M6 thread in the top to screw the can onto the bracket.
Needed to buy a piece of approx. 19mm diameter hose and adapted this to the existing neoprene hose. Works well, nice and solid and looks pretty good.

Re: Catch Can on VM Diesel

I watched a youtube video from Chrysler and they said they tested the new ecodiesel and the engine exceeded their engine life expectancy going in. Wouldn't they know during these long term tests if the engine needed some sort of catch can? I just don't understand what the catch can will do vs. the engines without using a catch can over it's life in service. Please someone explain. Thanks.

Re: Catch Can on VM Diesel

could you post the link to that video chad?

Here are two pictures of my intake at 1722 miles with the aircleaner hose removed. I stuck my finger in there, and sure enough there is a light vapor coating of oil on all sides. That pipe to the right is the PCV out tube that comes out near the oil fill cap assy. It's angled up at maybe 30 degrees, so there'd need to be some pretty serious volume for sludge or any liquid to enter the turbo intake. I'll have to disconnect one of the turbo outlet hoses and take a similar picture.

Re: Catch Can on VM Diesel

can we do that on this forum? I'll have to remove my hose and check mine. I have 5700 miles and never removed the turbo hose. Thanks.

Post a picture when you can... there seems to be a lot of confusion surrounding this topic
