Syncro TDI Info and the WBX Conundrum

[AndyBees]

I'm running the OE Diesel CAT ........ once it begins to operate (which is fairly quick, even on a cold day), the odor is very similar to chlorine (bleach). And, at WOT it does not bellow black smoke ... maybe a light cloud of dust.

A diesel vanagon never will be as quiet as a petrol one.
I have a 1Z mtdi with all the later JX exhaust and inlet setup, have hydro mounts and it is still a lot louder than the JX was (it runs harder so the sound is from combustion, direct injection vs indirect injection) and the JX was louder than my friends DJ.
And they wont be quiet without the factory underside cover tray.
Plus that the latest diesel vanagons in europe (from model year '89 I think) had an extra sound deadening foam like material inside the engine bay on all the exposed flat surfaces and a bigger exhaust silencer to meet the EURO1 environmental standard that involved a sound pollution limit.
The petrol ones had no modification required.

A friend of mine has an AFN e-tdi Vanagon. With late JX exhaust, AFN air filter in a 89 van. More silent than my mtdi, comparable to the JX but louder than the DJ.

Loyd Tulluch from the UK showed a photo of a factory VW oil separator that goes inline in the vent tube that runs from the block to the breather "puck". I have never seen this. Is this a worthwhile this to hunt down and install? If so, does anyone have the part numbers for the upper and lower hose/pipe pieces and the separator itself?

More worthwhile is to add a Mann Provent CCV filter.

On mine TDIs i through this tube out.
The seperator would make sense in the other tube going from head cover to inlet.

[westyventures]

You can see the Provent in the left lower corner of this photo, to the left of the valve cover.

Cool, thanks! Is that the ProVent 200?

Karl, I remember you mentioning having a runaway issue due to the provent install. What was the issue and solution to prevent that happening?

[westyventures]

[Waldi]

If you put more gimiks into your van, the more you have to worry about.
The engine works also without it.
But the inlet gets more oil with the installed tube from down to up, and its not needed on a 50 degree instal.

Edit:
Also the plastik part on the button with a O-ring is a part more that can cause leaks.

Instructions for installation of the Provent are here:

https://www.mann-hummel.com/fileadmin/user_upload/service/catalogues/pdf/ProVent_en_2013.pdf

There is also the Parker/RACOR CCV4500 which is basically the same idea, but different dimensions. I think it is larger diameter so that hurts in a tight engine space.
I saw this for $142. on this website:
http://racorstore.com/racor-ccv55024-ccv4500-hose-...gQodutQAKA

Aside from dimensions the downside is recommended filter change is at 750 hrs. They do also have a little RED pop-up button to tell you when the filter is blocking up so you need to change the filter...so far I have about 2000 hrs since the last filter changes and the RED button has not popped up. However, I am changing the generator oil & oil filters every 250 hrs.
If your engine is high mileage and worn out then you'd maybe want to change it every oil change. Provent states it depends on the application.

I have these installed on my Generators and they work as advertised.
The size restrictions would be what dictates which one I would use.

[Waldi]

He ?
A seperator filters the oil ?
Well yes, you have to replace the amount of oil that is in the seperator by new one.

If i worry about dirty oil, i change it.

[Waldi]

Sure there are alot of ways to do some things better on every system.
But the stock engines run about 300-500k km.
Isnt it better to leave them alone ?

[outwesty]

I've never had any issues with running a hose straight from the puck right into the turbo inlet pipe. Yes it coats the intercooler in oil but who cares ? I say keep it simple. I don't see a need for the provent.
