Where is the PCV valve on the 5.4?

Where is the PCV valve on the 5.4?
Or does it even use one? Just finished a bunch of maintenance, flush the brakes and power steering, rotate tires and change the oil. I got to looking for the PCV valve since it would be due for a new one. There's a couple things that look right on the top front of both valve covers but they don't look replaceable. Unless the tube they're connected to is replaced as a unit. I can't wait to find a repair manual for this truck!

I had mine replaced. My truck burns oil and they thought replacing the pcv valve would help, It didn't.
The pcv valve is built into your valve cover (on the driver side i believe).
you have to replace you valve cover to replace the pcv valve.
This is what the dealership has told me.
hope this helps.

Also note that these PCV valves are electronically controlled and heated.

Unless you have a mysterious lean condition, or are sucking oil, don't bother to replace it until at least 50 thousand. With the semi-synthetic oil on these tight clearance engines the crankcase ventilation doesn't get a huge workout like in the old days. A shot of electronics cleaner can rejuvenate one pretty well if it is starting to look dirty.
The older ones would get full of gunk from the blowby and thus reduce the aperture. Also the spring would get weak over time, increasing the airflow and causing a lean condition. Since neither of those problems is common in less than 100k on a modern engine I don't think I would worry too much about changing it early.

it is not as easy as previous model....according to OEM manual, it is closed loop system, which is lot hard to replace and requires few removal parts associated with it. With previous model, I was able to change w/i 20 seconds, now with this new engine design, I'm afraid to tackle it. Not to mention cost invloved.
