Another take on the RX Catch can install-new can location(standard can)

so despite the hose from the airbox being completely clean I saw this in the CSS. is this normal? hose is still 100% dry so the CSS is doing its job but it has me curious.
i also took off the charge pipe from the rear turbo and there was accumulation in the coupler near the turbo and around the turbo outlet. i didn't clean any of these pieces after installing the OCC so it could be old but still surprised me a little bit.
is this accumulation normal for others running OCCs or do you think it's old?

Looks like the CSS is working perfectly - nothing to worry about. That spongy material you pulled out helps coalesce oil from the crankcase vapor that reverses flow under boost. It allows the oil to drain back into the valve cover rather than being blown back into the intake (like in the OE setup) or all over the engine bay.
I wouldn't be surprised if what you see in the charge pipes is left over from before the CSS/OCC install, since they weren't cleaned.
The OE cleanside tubing or turbo seal blow-by are the only two sources of oil in the intake (unless an air filter is over oiled).
Not sure if ~some~ turbo seal blow-by is normal, or if ~any~ blow-by is considered bad. I'll look forward to others' input on that.

Yeah not doubting that it's working properly, more just curious. Also wondering how much or if any turbo blow-by is considered normal or cause for concern. Anybody else ever notice oil accumulation on turbo outlets?

If at all possible I would put those check valves somewhere a little bit more accessible, they can crack or break overtime.Colorado-SHOBro said:had the bumper off today so got a couple more shots of the can location.

Also I believe RX is using aluminum check valves now instead of plastic.
Might be worth a call/email. When
my CSS cap orings went bad they sent me out a new cap new check valves.
Good call glock i might reach out to them. the valves are in good shape and it's actually pretty easy to get at them from underneath the car with the belly pan off. Was your oil cap/CSS leaking onto your valve cover? i'm having that issue but it's minor. Tried to epoxy it and it helped a little. I bought my kit used so might have to buy a new cap or seal from RX.If at all possible I would put those check valves somewhere a little bit more accessible, they can crack or break overtime.

Yeah, the orings both cracked on the original.

Tracy still worked for RX and was active on the forum. Here's a pic of the new cap.

And installed
If your CSS is leaking and the o-rings look okay, make sure it's screwed together tight. The neck (with the o-rings) screws into the cap (which contains the hose barb). Mine loosened a bit, and started seeping oil. After re-tightening, no more leak.

That's exactly what mine looked like.Colorado-SHOBro said:i believe my older css seals up differently. mine has 1 grommet that seals the separator to the oil cap-no o rings.you can see where i tried to repair it and where it still has a slight leak.
