thanks for the reply chap, i'm no stranger to PCV and different engines across the automotive sector respond differently to changes in the PCV , basic concept is the same but how it is implemented and integrated can and does vary, anyway this deals with the 2.0tfsi found in B7's in its various formats.
I don't run a 1.8t so cant comment on its specifics, my post was targeted at the B7 2.0tfsi owners , but It would cover the same powerplant in other varaints, but the B7 was the intended variant hence why it was in the B7 forum.
there doesn't appear to be a setup that really covers both pcv issues with the 2.0 tfsi engine hopefully my project goes someway to addressing things.
I used a blank plate , 3 port tank setup as per my original post.
The PCV goes directly to tank under its own pressure, as does the vent from the rocker cover, return is via the TIP where the separated air is drawn back in by the intake vacuum.
As you say this works well as gases are drawn out of the engine with the help of the TIP vacuum so a very efficient setup.
To date I have had no issues whatsoever with the setup, idle's spot on all the time, oil consumption has been reduced etc, engine runs better … both IC are pretty well oil residue free now with only a few drops .
based on my experience thus far I would say its been a 100% success.
On the plate front I have been to several firm to get the plates machined up to my specs , they just are not worried about a few small batch runs, i'm not making money out of this just doing as a favour to others really so costing is a factor I have to consider.
If I had a cnc mill I would do them myself frankly, i'm no stranger to engineering fabrication.
anyway, thanks for the plate info i'll keep it in mind should the other plans fail.
cheers
