Lightbulb How to Check the PCV Valve

Shake Your PCV Valve
Do-it-yourself and save $20

Perform the world's easiest diagnostic test: Shake your PCV valve to make sure it's working. It takes only 5 minutes to replace a bad one.

Pull off the hose and remove the old valve. If it's bad, screw in a replacement and replace the hose.

This sounds complex, but it's not. Pull out your PCV valve every other oil change (this may be to often for most folks, its your choice)
In most cases, you'll find the valve on the top of the engine, connected to a vacuum hose. Some late-model cars don't have PCV valves, so don't beat yourself up trying to find it. Slide the vacuum hose off the valve and unscrew the valve.NOTE: on the 2 & 3 Valve 5.4 the PCV valve does not have a rubber hose attached; its a metal tube with a lock connector, much like the connectors on a wiring harness look for the clip and move it to the side and the hose will slip off. (be careful removing the connector as the o-rings may come out) dont bend the hose too far as the other end is attached the same way.

Then perform the world's easiest diagnostic test: Shake it. If it makes a metallic clicking sound, it's good. If it doesn't make noise or sounds mushy, replace it. But don't replace it on appearance alone—all used PCV valves look dirty.

On the 2 Valve 5.4 engine its located at the top of the valve cover on the passenger side
On the 3 Valve 5.4 engine The PCV, located on the driver's side of the upper intake manifold. The PCV, is connected to a vacuum line going to the valve cover

On the 4.9 it's on the very back top end of the valve cover, almost hidden by the cowl. On the 5.0 and 5.8 it is on the very back of the upper intake manifold I do believe.
I'm sure you know J, just want others to know that may read this.

I got 26,678 on my '06
and I just went out & poped the hood no PCV to be seen
I'll have to change the original post as the 5.4 I worked on yesterday was an '06 TWO Valve 5.4

so I guess now we have to find that PCV on the 3 valve

check your 4.6 and see if ya got one
