How to replace PCV Valve 2004 Mazda 6s V6 3L


Step 1: Identify PCV and remove connectors for space:
If you look at the back of the engine, there is a 5/8" tube running into the intake manifold. In picture #1, you'll see that this tube has a green sticker on it (red box #3). You can't see the PCV valve from this angle, but if you follow that tube down, you'll see a gray plastic piece. That is the PCV valve.



For step 1, we remove the 2 hoses and an electrical connectors (red boxes 1, 2, and 3). That will give us more clearance.

Step 2: Remove the tubes to get to the PCV valves.
Right, now you need to remove the 5/8" tube completely (the one with the green sticker). Picture #2 you can see that there are some hose-grips on that tubes, so using small pliers will help here.

After that, there is another adapter connected to that piece. Please see picture #3 and #4 for reference. That adapter must be remove because it spins freely. To remove, use your hand (no tools needed). Press the green adapter to release the grip and pull up.

Step 3: Remove PCV valve
You can see the full assembly in picture #3 and #4. Next is to remove the PCV valve. There is a shallow thread on that PCV valve, so you'll need to turn it to remove it. Use something to help you, like a clamp or pliers and rotate the PCV valve 1/4 turn counter-clockwise. This will be kind of difficult, but just keep working on it and it will loosen and pop out. A long reach nose-pliers can come in handy. In picture #5, you can see how tight it is down there.

Step 4: Replace and reconnect.
Replace the old PCV valve with the new one. Reconnect all the other hoses and connectors. Start engine and check for leaks. That's it.

hope this helps good luck!

2005 mazda 3 2.3l that is burning oil (no leaks)


possibly the pcv but check if your cars exhaust smoke is blueish or white in color if it does and your car doesnt have an oil leak then sure its burning engine oil along with fuel, the piston rings is defective, since you replaced engine oil the additive that the owner has put with the oil to prevent blowby is gone thats why it starts burning oil.....

Cant locate pcv valve on my 2005 mazda 3


Look under the intake manifold on the backside of the throttle body. If its turbocharged, you will have to pull the intercooler out to get to it.
