Hello Gents,
I was wondering if someone had located the pcv valve on this thing. I pulled the beauty/ giant heat soaking piece of plastic cover off. And didn't see anything that favored one. Installing a oil catch can to keep the blow by crud out of EVERYTHING.
Links to a diagram ,anything would be appreciated.
 
Well since no one replied I decided to find it myself. The pcv valve is located in the right side of the motor under the intake manifold. intake manifold is in the front of the motor . Follow your 4 intake ports downward they meet and create 1 larger pipe . (I.E. Boost pipe) run your hand down the right side of this pipe and feel for a inlet port with a hose clamped onto it. This hose is only 3-4 inches long . Follow it the 3-4 inches and you have found your pcv valve. These pcv valves aren't installed like older ones that just get pushed into a rubber grommet. These have a collar over them holding them in place. Mazda recommends using a small screwdriver with a rag over the tip as the collar snaps onto the Oem oil separator. To install the oil can I simply removed the hose from the intake manifold piping and the pcv valve. Installed rubbber fuel line from the pcv valve to the Inlet port of the can . Connected fuel line from the intake manifold port to the outlet port on the catch can . Pick where you would like your can before hand and make sure you can remove it prior to bolting it in.

The price on their site is nuts. Got mine off of amazon for 105. Well made ,but not sure if it's big enough and will check it weekly.

Final deciding factor on doing the catch can.

Not sure if anyone else installed a catch oil but I recently also got the mishimoto so I want to share my thoughts. Direct injection is notorious for carbon build up and especially amplified by the turbo so getting clean air through the intake is important. Installation was fairly easy. Looking for a good mounting point was the hard part. I have put 2k miles so far and this is what I drained out. It's a 20ml Robitussin cup for reference. It smelled much like fuel with fairly low viscosity. I was imagining it would be more but I guess the stock separator was doing a good enough job. However, my cx-9 hardly see RPM higher than 4k

Hey RATTL3R, thanks for this post. Would you happen to have a picture of your catch can installed? I'd like to see how and where you mounted it.
