Pcv valve where is the pcv valve located on a 2007 ford f150.  additionally where is the vacuum line connecting to it?

the pcv valve should only work on deceleration or when there is excessive pressure build up in the sump
max vacuum in an engine is 22 inches of mercury on hard deceleration and 15 "hg on idle to have vacuum in the sump indicates a faulty pcv valve so I would replace it with a known good one

PCV valve is normally located in one of the valve covers and connects to a vacuum source near the fuel intake assembly. Connecting hose is normally about 3/8 inch in diameter.

The PCV valve goes in a hole in the top of the valve cover, and is connected to a hose. It is the only hole in the valve cover other than the oil fill.

1997 Ford Truck F150 1/2 ton P/U 4WD 5.4L EFI 8cyl The PCV Valve is located: Under hood, center, upper engine area, top of engine, mounted in passenger side valve cover


Hope helps (remember to rate and comment this).

Your PCV valve has two port's, it also should have came with a plug ( Plastic ) That you break off of the PCV and plug the small one.Canada Emissions is the only one that uses both port's.

PCV Basics
PCV stands for Positive Crankcase Ventilation.
All car engines have a PCV valve and it is located on top of the motor's valve cover. There is a vacuum line attached to it. It pulls out of the valve cover and if you shake it, you should hear a marble knocking inside it. If you shake it and don't hear anything, it's bad. It costs less than 5 bucks to replace.


Location
* 4.0L is located in the valve cover near the brake booster
* 5.0L is located behind the intake manifold (engine rear)

NOTE-Most people that are asking actually want to know not only where is it but also how do you get at it to replace it.

Often answers say that you need to dismantle the intake manifold to get to it.
This is a major and unnecessary approach, for example, on the 2000 Explorer with a 5.0 V8

Below is an additional suggestion on how to access a PCV valve on an 2000 5.0 V8 Explorer

The PCV valve is on the rear of the intake manifold (the intake manifold is also on top of the crankcase so PCV valve has direct access to crankcase)

To replace valve and/or its bushing:

• Disconnect one battery terminal, unbolt/unplug the PCM cable (Powertrain Control Module connector located on the firewall) and firewall ground connection, depress underneath tab and slide the main cable connector (located to the right of PCM connector) off its mount.

• Move the cables to the right and now you can easily reach down behind the intake manifold to the PCV valve

• Service valve and its bushing if needed, reverse actions to reassemble

Hope this helped (remember comment and rated this). Good luck.

The PCV valve is hidden on top of the intake manifold down in a little enclosure. There are two small bolts holding the PCV cover. Often there is a fairly large vacuum line coming into the enclosure. Remove the cover and pull the PCV valve that sits down into a gasket.

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.

The PCV valve is located on the passenger side valve cover towards rear of engine.

Hello;
The valve should be in the valve cover on the V-8. There will be a vacuum line about 1/2" ID from the intake manifold to the valve cover.
Hope this helps, rate me high.
Thanks;
