i just dont like the way the pancake valve looks.
yea, 7/8" = .875
Ya I don't either...I might even out it right after the catch can. The only reason I like keeping it is because it is designed to allow air to pass through but not allow oil residue, so although I have the catch can to grab (hopefully) most of it, I still have the added security of the factory system that monitors pressure into the TIP.
The pancake valve lets oil get by. That is why your entire intake track to the throttle body has oil residue. The pancake valve is designed to close after a certain amount of positive pressure, iirc. Or something like that. I'm too lazy to search, but it does not function as a check valve. And to have a catch can be effective, it needs to have a baffle on it. Those passages are what really traps the oil (my old 034 vortex one worked in like an affect of having the blow by spin in the catch can, oil stick to the walls, and only the blow by gas would exit through the outlet). If no baffle is on the catch can, then you need to create your own baffle, such as steel wool placed in it (not quite sure the proper one to use, which won't shred and have metal strands end up in your engine).
And if Nic does not want the E-Scavenger, I'll take it. It must be SS though, and not mild steel.
The pancake valve should only allow air to pass by; in which there will be a mild amount of oil vapor but when functioning properly oil should not pass through (according to what I can find, I've spend way too much time reading about PCV, lol). A simple blow through test on mine reveals it is worn out. I am going to pick up a new valve today and run it in the stock location; however I will run the line across the front of the motor to hide it, it will then go under the IM and to my catch can. I emailed the Saikou Michi guy last night requesting his smallest can with a -10AN inlet and a 7/8" outlet (As far as I know all his cans are baffled accordingly but I will confirm when I hear back.)
This way, as I see it, the can will catch the oil vapor in the blow by (which I will drain manually), and the positive pressure from the crankcase will re-circulate through the intake as designed. I figure this is the closest to OEM application I can run without all the clutter...and let's face it, that valve under the IM with the T-fitting is just asking for a boost leak.
On the list for today:
plug IM bung for PCV system
Install power steering cooler
clean the passenger side of the bay a little more
No worries, I'll be totally honest; before last night I was foggy at best on how the whole system operated anyway, lol. Now that I feel I at least know how the stock system is supposed to work I can accurately come up with a breather solution with fewer weak points, and more importantly; less clutter...the hotside of my bay looks sooooooo empty and I haven't even really deleted anything.
No worries Rob, I'm going to pick one up today.
gear, not yet but I will shortly, I also fitted the passat power steering cover. I am thinking about going 2.0 FSI coils, a couple of my coils are cracking a bit and TBH I feel like me having them for 5 years problem free is more than good enough.
I certainly will, I will try to get some pics of the bay tomorrow and show how some things are routed.
A to do list because I like them:
-Install catch can (ordered)
-Route lines for the can (still figuring out my exact route)
-Secure driver side engine cover
-Install new ignition harness and FSI coils as well as new plugs/delete ICM (ordered)
-Replace compressor>IC piping silicone (ordered)
-Make a new FMIC bracket
-Install new power steering cooler in SMIC location
-Paint/powder valve cover (again)
-Roll front fenders/rust proof them

Next year I am not opening my hood next to you Geoff LOL. Damn that Looks good. and that Driver side Cover is good. Its off a B5.5 Passat right?
I was thinking of going this route as well as I don't like my Engine bay at all, but with mine having DD Status I can't take the time to re-do it. but now that you've gone and done it I am just going to leave my hood closed LOL.
or maybe I'll take the pic of your bay, blow it up, and lay it over mine at shows

It's got a long way to go before everything is tidied up, let alone clean...but it's getting there. By the way, the fit of the hose coming off the PCV in the TIP was bugging me in that last pic so I went and cut a new piece that was about 5mm longer so it went all the way to the corner of that 90* fitting.
I don't have any more pics of the breather system/catch can as I don't have the catch can yet. I think I'm going to mount it near the power steering reservoir, that way my cover will hide it and it's less line to run.
Yessir...in fact the hose from the turbo the intercooler doesn't quite line up...I ordered a new piece from silicone intakes though. Other than that I don't have any issues...it's a bitch to line up but once it's on, it's on.
Great shots of the bay, That's what a bay should look like Mind if i post up the video and a shot of the engine bay on my FB? Ill give credit where credit is due, just wanna spice it up and its an awesome video

Marc, I can't remember if I got that part from my uncle (Porsche/Audi/VW guy) or if I ordered it from the dealer. I initially thought it was a Euro only part but I think my VW dealer had it listed and it was just a matter of getting one sent in.
I can get the PN tomorrow.
