Boy do I fell like an A$$ for asking this but where is the PCV Valve on a 1999 4.6L?

I am getting a P1131 code which, among other things, the manual says to check the PCV valve. Well I pulled the air cleaner and rest of the fat tubes and there is a little oil inone fat tube. There is a skinny tube off that, going to the driver's side valve cover but there is no valve in that line.

The shop manual seems to showa tubecoming from the valve cover on the passenger side and going to a metal tube below and to the right of the air intake. I can't see anything coming off the passenger valve cover except the oil fill tube.

Somebody show me how dumb I am.

Thanks

Pete
