I only registered for the forum so that I could make a thread with detailed pictures of where the PCV valve is on an 03 F150 V6. I recently couldn't find mine and noticed that no one ever puts up pictures. What a pain for those that are searching.

It is on the passeger side of the INTAKE MANIFOLD. IT IS NOT ON THE VALVE COVER LIKE I HAVE SEEN STATED IN 99% of the threads over the matter.Here it is with 1 of the three hoses disconnected.




And here it is with 2 hoses disconnected. The 2 small hoses are heater hoses. The big hose is the actual pressure release tube that goes down to the valve cover.




Here are all three hoses taken off. You will need a T-20 torq bit to take it out of the intake.



Here is it completely removed.




And the notorious little baby removed.



I noticed, after 125,000 miles with no problems, a mysterious oil depletion problem. As you can tell by this picture:



It looks like my PCV valve was stuck open causing oil to flow into the intake. THe mystery of the F150 PCV valve SOLVED!
