Rx breather cap "breathing" oil

ok, i have something strange happening & I'm trying to figure out what is going on...I have a Vararam & the Rx catch can & Rx breather cap...I had the Vararam first, so when I installed the catch can & breather cap, I took off the varavram breather & capped the line...everything has been on for over a year with no issues (yes the hoses are on right)...last night I could smell burning oil while out for a drive...when I popped the hood, the breather cap had oil dripping from the filter part...what could be causing this? I put the regular oil cap & vararam beather back on for now...I'll have to check the oil once the engine is cooled to see how much I've actually lost...should I be concerned & remove the catch can for now as well? I remember there was another thread saying the valve could get stuck, or the PVC orifice could get clogged

I had a similar issue . . . I will have a hard time explaining but I talked to Tracy and he told me what to fix and it seems to have worked so try giving him a call. Best of luck let us know how it goes.

Easy fix....the orfice in the barb on the passenger side valve cover becomes clogged over time. It is easy to remove with a vice grips or plyers and then drill 7/64" the top single hole and both the bottom holes:





See how tiny those bottom holes are?

I want to drill the orifice too but Im unsure how deep do I drill on both sides?

I had the exact same issue, except my breather exploded

I took off the breather and uncapped the drivers side as well, as I had all kinds of issues, oil leaking from driverside head gasket in addition oil inlet, and lots of fumes like you probably experienced. It was not discussed about drilling the holes until a month ago or something.

Was intersted in this breather, but I've read enough "oil coming out" or "burning/smoke" stories with this breather that I'm not sure I want to do this mod any longer. Maybe down the road sometime.

is this barb still used when Maggie FI is installed or is that the one that gets plugged off?

The issue doesn't appear to be a problem with the breather per se, but with an OEM PCV component. The "oil-leaking" breather seems to expose the presence of a blockage elsewhere in the PCV system. I wonder how much oil collects in the trap on the OEM clean-air line when that orifice plugs up. The aesthetic improvement using the breather-cap was worth it to me because I didn't want to use the big retro-looking breather that came with the Vararam dangling off the OEM line. The breather cap is functionally equivalent with the exception of the oil-trap that exists on the OEM line (at least I think that's what the thing in the middle of the OEM line is)

I don't have this issue but wouldn't mind pulling out the Dremel and opening things up. The breather has shown that it does relieve pressure from the engine. But if the PCV system isn't working properly it could lead the breather not to work properly. And this clogging PCV system was the resort to a club members car bottom end to blow open because the pressure had nowhere to go. AND he was stock 100%! Also recall a few months ago ( I think it was Baylor or Smoke1LT) someone before stating that their dip stick was smoking and kept popping out. After switching to the breather problem was solved. That's why a catch can and breather is a good buy for those modding. I just need picture also where this is located to handle it today while I'm off.

Great info Tracey! Can you post a picture or someone post a picture exactly where this is located on a 2011 V6? Would like to drill this out before seeing this with my breather cap. Also how far deep are we drilling?

The breather is there to allow the engine to pull air in, not to relieve pressure...it will allow pressure to vent if it gets too high (mine was leaking oil)...I'll try to get mine drill out this weekend (damn weather sucks)

Not my set-up, but it's at the rear of the passenger-side valve cover: (RED circle)
