Losing Oil?

Losing Oil?
So in my 2003 F150 I have been losing small amounts of oil. I changed my oil about 2 months ago, and after I checked it yesterday the dip stick was almost bone dry. There are no external leaks but I noticed that I keep getting oil coming out of my PCV valve into my throttle body (the other end of that valve is connected to my valve cover). Is that normal or what? Where else could my oil be going? Cracked head?

Ditto! If the PCV valve is not flowing sufficient volume, pressure will increase slightly in the crankcase from cylinder blow by. When the intake valve opens, creating a vacuum in the intake tract, combined with the slightly increased crankcase pressure, the pressure will get past the intake valve seals, taking some oil with it. And you'll wonder where the oil went!
