PCV Valve replacement on 04 Sport Trac

[CodiBroney]

Hey I was wondering if anyone could show me what a PCV valve on a 04 4.0L sport Trac looks like. The one that is in it right now is completely hollow (not sure if that's how it's supposed to be) and the replacement one I purchased from napa isn't hollow and has a small aluminum pipe wrapped around it which looks like it's to keep it warm. (The one on my sport Trac also does not have this pipe around it). Can anyone help?

Motorcraft EV243a should be the same as the EV268 without the aluminum heater tube.

Use DIRECT part interchange when possible.
