Have a 2006 F-350 with the 5.4l 3 valve engine.

Noticed last year that my oil dipstick was popped out about an inch; pushed it back in. Next time I was under the hood, it was popped out again. It keeps doing this. The dipstick itself seems fine.

Did a search, and one possible cause is a clogged PCV valve. I was going to check it/change it out, but I'm not 100% sure where it is. I called NAPA to see if they had one in stock, and they said that they don't even show this engine having one.

So...I'm confused.

Attached is a picture of my engine of what I think is the PVC valve - there is a solid tube that goes about 10 inches from where I'm pointing to what appears to be a similar valve end (ie: as though there is a PCV valve at each end, if this is, in fact, the PCV valve).

Can anyone tell me if what I'm pointing to in the picture is the PCV valve and, if so, does the valve at both ends and tubing need to be changed (it looks like it's one piece).

Thanks.

Edit - it's not letting me post the picture. The valve is on the driver's side of the engine right along the dipstick tube itself.

According to Ford, the pcv valve is integral to the driver's side valve cover, and therefore needs to be replaced as a unit and is not a serviceable component like most typical valves are. But it could definitely blow out the dip stick if plugged, for sure.
