Well, I finally decided on an install of my Rx dual valve catch can on my 2013 Ecoboost. I decided I would deviate a little from the prescribed install procedures, primarily tying to avoid drilling my turbo inlet pipe or stock air filter box. Please note, this method is not emissions compliant. I wil let you know how it seems to work out once I put some miles on it.
For the dirty side, I installed the Rx dual valve catch can in the prescribed mounting location, out in front of the radiator.
Trying to keep everything fairly clean for the install, I ordered additional PCV quick connectors. I wanted to keep my original PCV hoses and connectors in tact in case I want to convert back to stock. It was a real biatch to get the new 1/2" tubing on the quick connects. I remember reading in another thread where someone had the same issue and ended up with seeping oil issues. I could not get them on all the way trying everything I could think of, so I hopefully sealed them up with some black RTV. Time will tell if this worked, but it seems to be pretty sealed up. The only other thing I can think of would be to go to a 5/8" tubing for the quick connects and then a 5/8" to 1/2" reducer (all of the tubing that comes with the lastest Rx dual valve version is 1/2").
Next, I routed the dirty side valve cover quick connect to the center port on the Rx dual valve catch can, and the IM quick connect to one of the exit ports on the catch can just like the instructions call for. For the IM connection, the 1/2" tubing coming off the catch can connector includes a one way check valve installed within the tubing. Therefore, I had to cut a small section of 1/2" tubing to run from the check valve connection to the quick connect.
So far, it is a typical install. Next, in order to keep from drilling my passenger side turbo inlet, I decided to just draw vacuum off the driver's side turbo inlet where the factory barb is located. This required looping a long section of 1/2" tubing around the back of the engine coming from the other exit port of the catch can. Once again, like the IM connection, there is a one way check valve installed in the tubing coming from the catch can connection. Therefore, I cut a piece of the 1/2" tubing to run from the check valve connection to loop behind the engine and to the driver side turbo inlet factory barb quick connect. Hopefully, while not providing as much vacuum as would be gained by accessing both turbo inlet pipes, it will still provide enough vacuum to evacuate under boost when IM vacuum isn't sufficient, and doesn't require drilling the passenger side turbo inlet pipe. I was noticing a good amount of oil residue on the driver side turbo inlet pipe from blow back through the clean side.
As far as providing fresh air, I merely capped the driver side valve cover clean air PCV inlet and installed a breather oil filler cap to provide filtered fresh air. I'm going to try this for awhile and see how it works. This allowed me to not have to drill into the stock air filter box to provide filtered fresh air which would have been required by either connecting directly to the valve cover PCV fresh air inlet or by installing the clean side separator. I do have a clean side separator that I may eventually install. Here is a pic of the clean side.
Please note this is an install for the Ecoboost. This would not work for the 5.0. All comments/suggestions/concerns welcome.
