Where is located the pcv valve - 1995 Nissan Altima

A PCV valve located in the valve cover. It may be located on or near the intake manifold, as shown here. A PVC valve located on the valve cover, with the hose that leads to it removed. A hose leading to the PCV valve is often kept in place by a clamp

5.7L


The PCV valve (3) is mounted into the top/right side of the intake manifold (2).


1.The PCV valve (1) is sealed to the intake manifold with two O-rings (2).
2.Remove PCV valve by rotating counter-clockwise 90 degrees until locating tabs (3) have been freed. After tabs have cleared, pull valve straight up from intake manifold.3.After valve is removed, check condition of two valve O-rings (2). __________________

the PCV valve is is typically located in the valve cover near the brake booster-4.0L pushrod V6. On a 5.0L V8 engines, the PCV valve is located at the back of the intake manifold.

you pcv valve should be located on the top or around the intake on top of the engine. It is covered by a little pcv valve rubber hose...it is easy to identify because it is similar to a radiator hose but a lot smaller...no where near the size of a radiator hose...but when located, the pcv valve just pulls out and to check for it being bad, shake it and it should sound like something loose inside the pcv valve (thats a good pcv valve) but what they look like, they should be a silver looking color with a small little neck on it

PCV valve location-2.4L engine


PCV valve location-3.3L and 3.8L engines

What throws everybody is that the pcv valve does not insert into the valve cover as it does most cars. This one on the 1999 explorer is located directly behind or in back of the engine on the top of the manifold. You can spot this easier if you take off the covering(four screws) on manifold then you will see two hoses that connect to a plastic pcv valve (that's what threw me). this should help.

Here's a picture to locate it..
So, when looking at the engine from above, on the right of the exhaust.
Procedure to replace it
1) Lift and support the front end of your car, or drive up on ramps
2) Get under the front of your car. The PCV Valve is located behind the exhaust manifold, a few inches below the valve cover.
3) Push up on the PCV valve to pop it out of the tube, or pull. You can get it out of the rubber tube with some effort.
4) Remove the rubber elbow from the top of the PCV valve. This can be re-used if it's not squishy. It can also be replaced cheaply.
5) Put the elbow on the new PCV Valve
6) Re-attach the elbow to the PCV tube
7) Push the new PCV valve back down into the large rubber tube

The general location mentioned is correct. However, unlike most PCV valves there is no hose connection to the valve. There is a single bolt that attachs the PCV valve to the valve cover. Loosen the bolt, then remove the PCV valve from the valve cover. It is inserted inside the valve cover. Very different from most PCV valves as far as attachment method to the valve cover.

it is normally located on the valve cover itself look for the black tube going into the top of the valve cover gasket
