Just Rob's 2.0tfsi Full PCV Delete project, and why you need to do it too.

[Gianni Lumadue]

This is my current temporary set up just rigged with things I had laying around the garage. Simply put a catch can in line after the primary oil separator to the stock back pcv port with a plugged intake path. Should work the same as a “half” delete?? Still stock plumbing to the turbo. Any reason this wouldn’t work?

 

[I'm Just Rob.]

problem number 1.
You will most likely be getting a vacuum leak from the primary input port ( see pic) to start with as the hose is not seated very well and the o-ring inside will most likely be not seated properly.
You may also be getting pcv issues with your method of bypassing the manifold intake link.

 

[Gianni Lumadue]

Okay, I plan on getting a real block off plate and intake plugs (rather than lug nuts and band clamps lol). But with location of the catch can and the plumbing in the pcv system shouldnt it catch most of the oil right from the primary oil separator?

 

[I'm Just Rob.]

What you have is an alternative method of a part delete, it will catch some but not all, you will still be getting the turbo outlet oil vapour with oil in IC's etc.
Also the quality of the design of your catch tank will dictate how well the air/oil separation takes place, just a plain tank will not really do much , you need a setup that separates air and oil effectively and that includes some sort of fine filter gauze or similar to perform the final filtering.
Only really effective solution is full delete, but all down to personal choice really.

 

[Gianni Lumadue]

Okay going to order the real parts and do a full delete like in your pictures. Thank you for your input I really appreciate it!!

 

[I'm Just Rob.]

I have moved forward a fair bit from that setup now and have a far superior design.
Hopefully coming into production to order in the new year.

 

[Gianni Lumadue]

Looking forward to seeing the redesign, the old one looks pretty bulletproof already.

Hi Rob,
Thnks for this thread . I want install your PCV delete kit on my 2.0 TFSI engine, but it's impossible to buy blanking plate on turbo in Czech republic and postage f. e. from UK is crazy. Pls can you (or somebody else) write basic dimensions of this piece of steel . Thnks

I have some spare plates if you want one for the postage cost if that helps.

I am also interested can you send please some kind of drawing?

what turbo are you fitting as the're different sizes.

K04 064, do you have a block off plate on the valve cover, also (drawing)?

I have K03 turbo in Škoda RS.....

B7 A4 is K03

Yea, it's the same engine.... VAG 2.0 TFSI EA113.

I Will buy PCV delete kit and close the input from crankcase....because full block off plate is not selling in our country. Dont know, why.....

Thnks for your offer. PM send

If you need to make your own turbo return blanking plate here are the approx. dimensions.
made in 3mm steel, just choose your flavour mild or stainless.

 

[can31]

Thank you Rob! So you just put this blanking plate under the hose that connects valve cover and turbo or you have completely removed that hose? Did you than somehow block the rear of the valve cover?

If you block the rear port how do you plan to get of the Crankcase pressure?

I'm thinking about it right now hmmm, connect it to the exhaust? What others do? For what then turbo return blanking plate is used for?

What setup do you have, are the front ports blocked? I found the most comfortable setup for my car was to block of the front ports, leave the first oil port as is and add a catch can to the rear port.

I plan to use pcv kit with catch can for the front part of valve cover (pcv plate with 3 connectors).

Robs original setup? Yes I was running that setup but recently changed.

I wont go to the exhaust. I will leave the back parts as is. How did he finished?

I feel the problem is from the rear port, ill send you a photo of my setup.

Keep in mind my original setup was a full delete not part delete .
If you are wishing to still use the VC pcv ports in any form then its not what I set out to do.
The whole object of the full delete was to bypass the VC and OEM PCV setup, by eliminating the source of the problem to start with , the returning of oil laden vapour back into the engine via the inlet manifold.

Im back to using the VC ports as i think i caused too much Crankcase pressure.

Here is my current setup, note that I have deleted the small port that goes into the turbo and connected it directly, (sth i read the VW guys were doing).

If the primary oil separator can vent fully without any restrictions then you will not get any backpressure problems.
Also if the valve cover is being vented correctly there will no problems.

My original setup worked just great for me , I've only changed recently as I came up with a far superior setup with less hardware and less intrusive in the engine bay.

 

[can31]

TBH I don't understand what have you done i.e. what connects to what.

Two things jump out at me chap.
one, why did you change the vacuum pass through line on the VC?
second , as you have the primary oil separator connected to the VC secondary separator have you ensured the front pass through ports are not blocked with that plate, even if there is a small obstruction you will get backpressure as there is nowhere for the crankcase pressure to vent, it will just backup to the crankcase.

Which you're finally going to put in a complete kit and sell to us to fund your BHP habit?

 

[I'm Just Rob.]

Indeedy .
But not really sure that many are too fussed about doing the mod in either form at present.
For now i'm just keeping it for my own usage , i'll put them up for offer again in the spring and see what occurs.
I need to crack on with the engine build until then.

The plate connects the first 2 ports together, the primary still goes to the primary port, the only difference is i have added an additional separator to the rear port.
I saw the vacuum pass through line fix on some GTI forums claiming that it will limit oil on spark plugs.

Not sure how the vacuum pass through will limit oil on spark plugs as it's just a vacuum passthrough, if one is getting oily plugs then it's oil in the combustion cycle not via the VC pass through.

So its useless?

Ill explain it to you, but first you need to know the the most optimum setup is Robs setup, but due to the limitation of some hardware I had to use my setup.
I used this block plate, i connected the line coming from the oil filter to the only port on the plate, the rear port coming from the VC goes into the in port of catch can, the out port goes back to the turbo.

The vacuum line isn't , you need it , but there is nothing gained by not using the oem vacuum line pass through , unless your VC has a vacuum leak which is not unheard of.
Sometimes the seal of the inner plate on the VC can develop leaks , in turn leading a vacuum loss in one or more of the chambers.
The leaks tend to be in the pcv pass through port section for some reason, but can be in the vacuum line pass through.
