Nice that, a picture speaks a thousand words, so this is your setup?

Black corrugated (over intake mani) = C1 and C3 head breather pipe
Blue pipe = C2 and C4 head breather pipe
Black glossy pipe = Crankcase breather

All VTA.

Wilst not to discredit Mr Finch's knowledge or workmanship , & not to bore everyone with my full spec ,,
Car runs a oil cooler with thermostatic sandwich
Killer B pick up & windage tray
PCV & EVAP delete
Front cam breathers have been blanked since day 1
Never had an issue with oil
Gets dropped every 2000mls & has covered 15000 Mls
Never skipped a beat ,, but hey ho it may go "POP" tomorrow lol
It's due a check over & refresh ion the summer when I'm pi$$ing round on bikes , so I'll take your recommendation on board & change the set up & few things around.

I could equally say do you know more then Subaru who designed the engine? Yeah ok mate....really? But no.

First everybody gets things wrong. Me included.

Second I am sure that he knows his stuff and has far more experience then me.

However I did not say he was wrong. I just stated some simple (as I see them facts). Perhaps I am wrong. But instead of a concise answer explaining why I am wrong you just add a bit jest at my expense. Great cheers, exactly as expected here unfortunately.

Personally I would far prefer it if we could ditch the whole system as I go to great lengths to dump everything I can out of the bay. The Fuel EVAP system has gone (properly not the easy way) as it actually did not harm performance or reliability to remove it.

The PCV system however according to my research appears to be useful. So I will keep it. Unless a person can prove to me that Subaru's system (their engine design) is actually an error on their part and that their engineers got it wrong and wasted their time making something which served no purpose in the first place.... seems unlikely? It's even backed up by their own service manual.

Once again. I am not saying catch cans are bad. They are good. I am not saying your engine will blow without PCV. What I am saying is that there is a reason for PCV. Some race engines go to great lengths to create a PCV system at big cost (look it up). It seems to be beneficial to the engine far more then a VTA setup. I know most people VTA through a catch can and they are free to do what they like. But I like to think that these forums are about more then mocking **** cars on SIOC and that we can have decent conversations about technical stuff.... maybe not.

Also note I am only talking about classic engines with one breather on each head. Newer ones with double breathers I have not looked into.

Im guessing that the PCV should be kept then
