I purchased a pcv valve but I am unable to locate it on my car.3.5L engine.2005 uplander.

positive crankcase valve is located on the back of the valve cover on the right valve cover i believe if your looking at the engine, you will need to remove some hoses to be able to access the pcv valve, here is a diagram to help

pcv valve is located on the valve cover of the engine. you will see a line running close to the middle of the valve cover gently pull the line out of the valve cover, the pcv valve will be on the end of the line. take out the pcv shake it, if it rattles it is okay, if you don`t hear a rattle it needs to be replaced. Also I personally would change the pcv valve every 25,000 to 30,000 miles because they are usually inexpensive.

looking at the engine from front it should be in the right valve cover. a hose comes from the pcv valve to throttle body.to replace it, just pull up on valve to release from rubber grommet. have a good day !!

On the front of the engine, to the right of the eng oil fill cap. the only hose there.It is the PCV valve...

If you have a 3.3 or 3.8 engine the PCV valve is located on the back valve cover and un screws counter clockwise careful its only plastic

Look for a large rubber tube attached to the manifold port located on the top left side (passenger) rising up and and then curving down to the rear valve cover pcv port. It is a squeeze, but work the hose off the pcv port, and "voila" the pcv valve is INSIDE the port. Pull it out with its attached grommet. Do not attempt to clean. Replace, only, and save the receipt for the engine warranty. This engine can burn oil if it is a valve seal or manifold plenum problem.

Its in the upper intake manifold on passanger side. Inside the manifold. Be sure to put o-ring on pcv or check engine light will come on.

It is bolted into the rear valve cover near the passenger side.

The PCV valve is located in the valve cover on the passenger side of the vehicle. The valve is closer to the firewall than it is to the front of the engine. It has a hose attached to it and threads into the valve cover.
