I need to replace the VCT solenoids on my 07 Expedition. I've read on another forum that the AC needs to evacuated and a line disconnected to get the passenger side valve cover off, but they were speaking specifically about F150s not 5.4 3V in general. I've looked at mine and it looks like there might be room to get it out. I was hoping someone could share an experience of having this done. If it comes down to dropping a motor mount or something like that (a suggestion on the other forum) I think I'll just have a shop do it.
