Thanks Tracy, I appreciate the offer of help!... It's all good...Done that guinea pig thing before for sure. Definitely will get pics and mounting options. Only concern is space around the EBPP hotpipes, but I've Got every faith in Jeremy over at Black Market Racing. SwampRat will be working on one too, so we'll get the info.Tuner Boost said:
RX crankcase evac system on the Ford Flex

Been working with Tracy... He's sending out a couple of fittings and a different bracket than came with the can... May just be the answer for the SHO. If not I'm putting her up on a lift to mount the can low to right rear. It's not the HPs or DPs... there just isn't as much room in the SHO engine compartment compared to the Flex
Tracy and RX Performance have provided stellar customer service...second to none!. :thankyou:

My install is next week...
Did you get yours done, BMC?painterpatt

I actually just got back from RX, Tracy moved my cleanside tap to intake tube right net to air cleaner. I was getting oil in cleanside instead of can. He's going to post about it after he gets his arms out of a Corvette

Hi All, I forgot to take pics, but Pat can of the after. Yes, the drill/tap spot on the front charge pipe was upstream of the barb for the cleanside and was over powering the flow when cruising and in boost. So we moved the cleanside separator line and fitting to as close to the air filter as possible and cured it. This also allows no drilling for the front tube!!! Just use the existing OEM barb the cleanside tube did attache to. I also recommend cleaning the CAC (remove to do) first as he still has a good bit in his CAC.
Cheers!
Cheers!

First off: I know Pat didn't have much oil in his can...from what I see in your post I'm guessing because of the constant hyper-vacuum to the clean side separator the coalescing material in the separator was working overtime and the evacuated mixture was being either returned to the oil or fed through the intake? Due to a lack of vacuum through the rear PCV, this was acting as the constant "clean-side"?
Second: So for those of us (me) that have already installed; is there something we should be doing?? Instructions please.
Third: If I'm reading your post correctly; you attached the front-side outlet, from the can to the oem vacuum barb that the clean side separator WAS attached to. Then, extended the clean side separator closer to the air filter to decrease vacuum. Correct?
Questions:
- Does the outlet hose from the can for the front side now only have one port instead of two? ...OR does it T-into the oem barb, then go to the rear intake pipe drill/threaded fitting?
- Will another hole need to be drill/tapped near the airbox now?
- Best recommendation for plugging the now un-used drill/threaded fitting on the front pipe?
- Is the problem definitely solved, or would it be better to wait prior to making any changes?
- Is it hurting anything to drive the XSport currently, with the prior install?
TIA for a comprehensive reply.

Clean side is now tapped next to air cleaner, move line from can to stock location on tube that clean side was removed from. Cap barb that was drilled into tube or remove and plug. Or I guess you could just cap the factory port cleanside was attached to. 
Thinking about all of this...a couple other ideas popped up I would love input on:
if the problem is the clean side separator getting too much vacuum, would it make sense to just constrict the cleanside hose, rather than re-routing it? (ie. reducing it down to a smaller size, or adding a check valve to slow the flow?) Maybe the two front ports could be juxtaposed, then restrict the cleanside? Just some ideas on how else to skin this proverbial cat. I would rather not leave an unused port in the intake unless I have to.
How would one test to see if it's working correctly?

Well that's going to be a little more difficult with the metal pipe on the K&N intake. With the Rx installed the cleanside separator hose is just a fresh air intake now (besides for a moment when switching to boost) right? Why would you want any suction on the end of this line? Is that what the "off road" oil cap does is just put a filter on the air intake for the PCV system?
