Question about 1997 Mazda MPV
PCV Valve is in the end of 1/2" or so size hose inserted into a rubber grommet in the top of one of the valve covers. I believe it's on the passenger side closest to the firewall.
If you have the 24 Valve engine, the PCV valve is on the drivers side of the engine compartment, if you're facing the front of the vehicle, just under the air intake hose. Its not directly on the engine but rather in line with the oil separator tube/hose. Follow the black accordion tube from the air cleaner to the throttle body valve. Place your hand on the bottom of the throttle body and you will find the PCV attached to two short rubber hoses. Hand access is limited, so you have to feel for the PCV and blindly remove the hoses from the PCV. Be patient, and allow time to finesse the new PCV onto both hoses.
I recommend purchasing this molded new hose for a few dollars from your Ford dealer. They tend to clog or collapse after several years. The whole process can be done in 15 to 30 minutes and save you a lot.
Good luck and hope this helps. keep me posted

You have the wrong type hose on the pcv valvle. It isn't vacuum hose.
