SOURCE: pcv valve

I know it attaches to a small hose and the body of the valve inserts into the head. Mine is on the right rear in a 2000 Explorer Sport. The guy at Autozone always is happy to help me when I ask...too short to get over the fender if I don't have a step or block to stand on. Not a very expensive part.

Remove the hose from the PVC,
If the hose is stuck, try turning it in place with a set of pliers.
Sometimes a Flathead screwdriver can be used to pry it off, but can be dangerous and/or rip the end, of said hose.
However, if you are replacing it anyway, you could cut it off.
Remember to save a segment of hose for sizing.

I have a 97 mazda mpv and need to find the pvc valve on the engine?

PVC Valves do not need to be replaced
Never have

99% of them, have been on the valve cover
for at least 40 years

Unless you have a pcv vacuum hose leak
they do nothing, as far a your engine goes

They are there to regulate crankcase fume

Need to start studying & stop listening
to all the hype,including repair shops that
sell these things for no reason.

Where can i find pcv valve of 2.5 engine mazda mpv,where is it mounted in the engine

PCV Valves are located on top of the valve cover and allow gas to escape from the blow by of piston gases.
Look for a black plasltic piece that is inserted into the top of the valve cover near the front of the engine with a rubber hose connected to it.

1998 mazda mpv code p0170 erase code car runs fine but when i stop for a few minutes it is hard to start and runs rough the engine light comes back on and the code will read p0170 again

This code indicates a fuel ratio problem. I would start by inspecting all the vacuum lines, including the pcv hose and power brake hose. Carefully inspect the air intake hose. This is the large hose between the throttle body and the airflow meter. If this hose is cracked or loose the computer will not sense how much air is being drawn into the engine and it will be hard to start.

Air intake tube?

This sounds silly but try using a piece of garden hose (or any other hose) held to your ear, using the free end as a probe. You will be able to pinpoint the source of the hissing noise and see what needs to be fixed.

2003 Mazda Mpv jerks when idling abd breaking

Check to see if you have a MPV that has been included in the recall for the PCV line. Yes it is difficault to get to on your own, however they have special tools to reach behind the manifold to remove the line and install a new one. If you do it on your own it is very difficaul and will take a few hours as a I did before I found out about the recall. The service dept. should have asked you about the recall when you went to get the part from them. Where I got pissed was when they did replace the hose the faulty line had fouled the pcv valve and they did not bother to replace it and that is tucked under the intake manifold and under the fuel rails.
