Vwr catch can ?/concern

[Navi]

Perfect, thanks Navi. Does the catch can hit the frame of the car on the bottom with that valve in place? Or does it clear it fine?

it clears fine. I thought you were removing all that stuff though. Wasn't it filling with oil?

Yes, but I'm considering adding a line from the can drain to the oil pan. lol. That way I don't have oil flooding my turbo and it just returns to the pan. But I might just combine it with OEM PCV instead of an aftermarket plate.

Also I'm late to this party but you are probably leaking a lot of boost at the N80 valve. Several plates like VWR send full boost to the N80 and I don't think the N80 is designed to handle it. OEM, Spulen, and Leyo incorporate a check valve to prevent boost from reaching the N80.

Not too sure about this. I put a check valve in that line so positive pressure cant go to the n80 valve and it didnt change anything for me. I also pressure tested the crankcase at idle through the dipstick tube and found from idle to revving to 5k it gains 2 psi in the crankcase

I don't think that it will catch anything without the plate. The one I originally installed didn't.

Interesting, not sure what to think about all that. I know with the stock PCV the crankcase is under vacuum, and with the aftermarket ones it's basically neutral. FWIW. Sounds like you may need to do a boost leak test?

I don't really care for it to catch anything. My issue is at the road course, the oil surge issue floods the PCV and dumps oil into the turbo. A catch can would act as a buffer and the raw oil would just drain back to the pan. I would use the valve to keep it closed for daily driving since I don't have problems there, and just open it up at the track (after draining it of course).

I already boost leak tested it and didnt find any leaks anywhere. Tightened every clamp possible too. I'm gonna try going to b9 plate and if that doesnt work then I'm gonna take the line off the inlet from the catchcan and put a breather filter on it

I’m happy to confirm that the Catheter with the 3/16 tube method works PERFECTLY. Made draining it a breeze. 0 mess.

Do you have a link to where you bought the 3/16 tube?

I just went to Ace Hardwear. They had it. Was like $1.50 or so.
