does the 2002 xl f150 v6 4.2 ltr. have a pcv valve? The parts stores say NO?

At the passenger side valve cover in the back it has a approx. 1/2" black hose that goes into the valve cover. Follow that hose up and it goes into the PCV valve. It also has 2 small hoses that attach to it, with a coiled metal hose that goes around it.

It's up front under the idle air control valve

Another person on you tube says that 2002 has two Pcv valves: one in the passenger side and one near the oil cap. I found them ; but don’t know exactly whether they need 2 or 1 only. V. E

And I had problems with my 2002 . The light service soon and don’t know if that’s the problem: cause I noticed that my truck only is with two hoses , but doesn’t have the Pcv valves.
