Trying to replace a PCV valve on my 2006 F150 5.4L. I've googled it several times, changing the wording and videos & pictures don't look like anything that's under my hood. First of all the PCV valve on my truck is on the drivers side, & it looks like a 1/2" steel tube pressed into the valve cover. Now on the passengers side there's a vacuum line from the air intake body to the valve cover, it looks to be 3/8" line. The fun part of all this is that both line were seized to the steel tubes (PCV valves?) and I ended up damaging the (supposedly) quick disconnected ends. Does anyone know how to get these steel tube ends (PCV valves?) out of the valve covers? & or have part #'s for the replacement parts?

They're not serviceable - and technically not a "valve". There is no "positive" crankcase pressure. The 5.4L constantly aspirates "filtered" air and crankcase vapors from right side of throttle body - into the bank 1 valve cover through the crankcase - out of the front of the bank 2 valve cover - through an "insulated hose" to the heating element into the belly of the intake manifold (sorta isolated from but near intake runner tubes to cyl 7 & 8). The heating element is activated by the PCM below 40º F IAT.

Can the steel tubes coming out of the valve covers be replaced? The one on the driver's side is badly corroded & probably a bad seal. The passenger's side is rotted off at the curve.

Wow, how is your truck that rusted?

Western New York salt, plus it sat in the pole barn (stone floor) for 18 months while I went through chemo & radiation treatments.

That'll do it. Hope you are doing well.
