AAZ advice needed, oil breather etc

[Team WorldTour]

Damn you, Samba for your thought out ideas! and logic! How can I compete?
So, I said 'fuck it', and got the breather tube that I recommended against:

And today I installed it.

First off, for the record, It shows the block-off plate in the Bible:

Here is the block-off plate as it should be:

Here is the block-off plate removed:

...and the resulting hole:

Here is the breather tube, installed:

And since I no longer needed the hockey puck, I decided to break it down.

Puck:

Puck underside:

Puck internal diaphragm:

Under the diaphragm is a spring and holder:

So, to refute the claim, when the puck is laid over at 50°, the collected oil WILL drain back into the motor.


Sorry for the crappy pictures. My phone is non-upgradable Android 6, and Google went and limited the camera app to 7.1, so now I'm stuck using the bundled camera on my phone (CAT S60).

The Bentley shows the block-off plate, but that isn't an AAZ. That's a 1.6 in the Bentley. Allowing the crankcase to vent from that location is an improvement. With the 1.6 the blowby gases need to vent UP the head oil drains while oil is trying to drain DOWN those drains. Either way works, but VW went with the two -port puck and the second tube for good reason.

Thanks for taking that apart. I've done similar before and have posted several times on various forums that the main purpose of the puck is to prevent runaway in the event of a blocked intake tract (e.g. clogged air filter). In that situation, the vacuum on the crank vent pulls the diaphragm against the light spring pressure and plugs the connection to the intake.

I imagine that any oil separation it does is due to the cyclonic effect and the inertia of the oil droplets. I also imagine that having the puck flat assists in that motion. VW actually changed the angle of the top of the JX valve cover (1.6TD Vanagon) so the puck stays more flat, which seems to confirm my imaginings on that.

Either version works but aside from ease of fitment, there is not any benefit to the 1.6TD puck over the Mk3 version and there is benefit to the Mk3 version over the 1.6TD. Rest well knowing that less oil will get ingested by your intake because of the better venting you installed.

Well, only an idiot would continue holding an idea that has been proven false.....

Are you trying to imply that am an idiot? I'm not sure how else to interpret your post. It's a bit startling when someone responds with unprovoked insults in the midst of a friendly technical discussion.

What 'idea that has been proven false' are you referring to?

[Team WorldTour]

Sorry mate, you've read that wrong.
At the beginning of this thread, I held a different opinion.
Through logic and facts, I changed my mind.
Then I stated:

[?Waldo?]

Ahhh, thanks for the reply and explanation.

I'm grateful for this thread!

I've posted a few times about my own probable crankcase ventilation issues. My AAZ runs just fine except on extended highway runs, during which it has shown an inclination to spit oil out of the filler tube. I'm not having problems otherwise.

After reading this, I'm planning on making something that will allow me to run the vent to the intake.

[Team WorldTour]

I am very ready to call this a placebo effect, but damned if my van did run just a bit quicker today while out and about. Not faster, just quicker.
Like third gear roll-on. The old boy had some power and got up and moved!
My engine is (comparatively) new (30,000km), and it felt like it had just a bit more power......

Oh, on a side note, I was visiting a buddy tonight, and I told him about the vent pipe. He told me that it is important to change the puck every 60,000km.
He says it fills up with crud and grit which can then be sucked into the turbo with the oil vapors. I told him that mine was from the old JX motor that died 4 years ago.

So, everyone- hit up eBay and get a new one, no telling how old the current one is!

Nice one, thanks for the link too. It will be very interesting to see how you get on with it.
Cheers

[ndorian]

Is the German puck really worth four times as much as a knockoff?

[ndorian]

I realize that for a lot of parts OEM is best. This is a fairly simple design and I would think that if the part is to be replaced as often as mentioned earlier the cheaper option should at least be considered.

[dom777]

I found a puck on vw heritage for £6 + £5 p+p. Pipe on Amazon for £14 inc delivery. Total cost £25. I'll see how they stand up, but not a huge amount oof money

So, oil level is still normal.

Maybe it's just the vapors....https://kelleepratt.files.wordpress.com/2016/01/fw_gonewiththewind-gif.gif?w=610
