PCV Valve Location
The PCV Valve is located underneath the air intake manifold. There is a rubber hose connected from the air intake manifold to the PCV valve. The valve is attached to a plastic plate on the bottom front of motor. It is held on place by five 8 mm bolts. Use caution when removing the PCV valve. It is held in place by a plastic ring clip . Plastic pry tool will help minimize damage to the PCV valve mounting point.

This models does not have PCV valve! Only gasoline engines has the PCV valve underneath the air intake manifold, but i have found the problem!!!
Mazda 5,3,6, 2.0 diesel 2007-2010, low power, blue smoke, high pressure in the upper crankcase, the opinion of many mechanics was that the set of engine segments is finished, after much research and study, I discovered the problem: washers copper in the injectors heads were the problem. Due to the wear, they no longer sealed properly and all the pressure in the lower crankcase passed by the washers in the upper crankcase, including the oil in the bath was removed through the turbine ... The solution! Manually cleaned Denso deposit injectors, new washers and it's ready to go, no smoke and power like new! It is recommended to do this operation at an interval of 30,000-40,000 km if you detect blue smoke on the dipstick or the oil filler cap. I mention that the synchronization of the Denso injectors was done automatically by the car's computer.
