Where is the PCV Valve on a Mazda B2300 2003
If you have the 3.0L the pcv valve is located under the fuel rail under the intake manifold. You cannot remove with finger power...The valve turns out counter clockwise with some force.
The PCV valve on a Mazda 6 V6 is located on the valve cover near the back of the engine. The PCV valve is usually a plastic or metal part that looks like a small tube sticking up out of the valve cover.
does the 2006 silverado have a pcv valve
Pcv valve on a 3.0L V6 Mazda tribute is buried under the intake manifold. It is approximately under the throttle valve. It is NOT inserted into a rubber grommet in the rocker cover. It is screwed into the lower intake manifold. Use a deep 7/8" 12 point socket to twist it 90 degrees to the left to remove it and reverse this to put it in. Be sure to replace the PCV valve when replacing the spark plugs since all needs to have the intake manifold removed to get to them.Normally located on top of the valve cover.AnswerMost are inserted into a rubber grommet in the rocker cover.
The 06 silverado 4.3 does not have a PCV valve.
Unfortunately,, the Mazda engineers located the PCV valve on the 3.0L engines under the intake manifold--essentially right under the throttle body. You can't see it until you pull the upper intake manifold off. I would definitely change out the PCV valve if you are replacing the spark plugs since the manifold has to come off to get to the back 3 spark plugs. A big hint here,, the pcv valve has to be turned 90degrees to the left to get it out of the housing.. a 7/8" 12 point deep socket seems to work. Look at your new pcv valve and you will see what I mean. Once you finally feed in the new pcv valve,, it must be turned 90degrees to the right to get it onto place. A 12" set of needle nose pliers might help also to get the hose off the pcv valve. Gerald
The manufacturers of Mazda Tribute placed the PCV valve of a 3.0L V6 AUTO 200HP under the Lower Engine Manifold attached to a hard black metal rectangular shaped housing in the center of the engine. It will be sticking out of the end. The PCV should be black round plastic material. It is similar to the Ford Focus or Ford Escape PCV version. Although when you search the internet or at certain stores, it may be metal. This type will not fit my Mazda Tribute. Also, the Upper Manifold ( the black plastic compartment), ignition rails and the spark plug harness over the engine must be carefully removed. I had to also removed the radiator hose at the end of the lower manifold to gain access.
On a 1999 Mazda B3000, the PCV valve is in one of two places, depending on the engine. On SOHC 4-cylinder engines, the PCV valve is mounted on the oil separator on the left side of the engine. On DOHC 4-cylinder engines, the valve is behind the coolant bypass hose..
Change the PCV valve located on the valve cover
On my 1997 Protege a hose runs from the valve cover to the air intake assembly. Where the hose connects to the valve cover is the PCV valve.
