PCV oil catch can install
I have a 2019 CX 5 GT Reserve (turbo engine) so I ordered a CorkSport oil catch can to collect the vapor crap from my crankcase that flows thru the PCV tube. This catch can has a screw-in dipstick and a bottom drain port with a ball valve handle. Think of an oil catch can as an "PCV air cleaner".
Hopefully it will keep (most) crankcase vapor from building up on the backside of my intake valves. This buildup is B/C MAZDA, like many other vehicles today, uses direct injection. Thus there is no fuel coming from the air intake ports to clean the intake valves as with the older port injection style.
Additionally I will have my dealer inject BG Platinum cleaning fluid on the intake valves every 15,000 miles. The oil catch can should get some of the dissolved and small particulates form this cleaning as well instead of putting it back through the intake valves.
This is not a cheap date with over $200. for the catch can system and likely at least that much for install by my ASM certified garage mechanic. But I want the garage to install it so if something goes wrong I can point the finger at them IF they screwed up, which I highly doubt they would. CorkSport sends detailed photo & text instructions for the install.
BTW, I got a CorkSport can because they are Mazdaspeed experts.

Catch cans are great so PLEASE don't take this the wrong way...
On a TurboCharged (even a normally aspirated engine) with direct port injection a water/meth system may have been a better investment. The water/meth goes through the intake and will pass over the back of the intake valve keeping it clean of any build up.
Depending on your location the average cost of the system is about 350-425. Installation would be about the same as the Catch Can which will reduce but not eliminate oil vapor contamination.

All my vehicles SuperCharged, TurboCharged, normally aspirated and even carburetor have some form of water or water meth systems to keep the valves,combustion chambers and the of the pistons carbon and gunk free. My current 2018 Mazda3 with a 2.5 NA to which I am in the process of installing a system on it.
And yes I will even install a Catch Can system as well!

CALLISTO,
I'll look up water/meth injection to see if it is a good adjunct to an oil catch can.
tnt,
If every cylinder is within factory specs for pressure then the induction system may be at fault, from the intake valves on out to the throttle body.
This includes the PCV setup and any factory oil separator (if so equipped.) as well.
Finally, you may want to check ALL gaskets and O-rings for leakage. A compression check would let you know if any cylinder had a head gasket leak.
A good garage with all ASM certified mechanics might be able to find the problem if you can't find it.
