Hello - looking to replace this part, do you know specifically what it is called or the part number? I keep seeing PCV valve, but everything relates to the left side of the engine. See yellow and purple hose line.

1998 Ford Expedition, XLT. 5.4L engine.

Hi, I have a 1998 expedition XLT 5.4 4×4 AWD that is uncannily like yours, identical engine bay from the battery type connections which are aftermarket and a lot of other little details I was about to ask if you sold yours a couple years back cause that is when I bought mine. Anyways. I have a problem maybe you can help, the heat in the front or back doesn't work, I had a plugged heated pcv valve fitting and hoses so I had to do a bypass, my gauge always runs on the low side, tried changing sensors etc. Is there a valve for the heat or could it be a vacuum leaks somewhere crazy? Any help is greatly appreciated.
