Your PCV valve is on the back of the lower intake manifold. It's pretty tight back
there. IIRC you can reach it easiest from the right(passenger) side. When you remove
the valve also remove\replace the filter down inside the hole. They get plugged and
impede PCV operation, thus raising crankcase pressure, which can cause oil leaks. I
have a tool for this but I've heard that a long drywall screw can be threaded into the
filter for removal. The filter is supposed to prevent the PCV from pulling in oil.
I've heard a lot of people say they just remove the filter and throw it away with no
problems. I've always replaced them though, so YMMV if you go that route.

Hello can you use reg 3/8 hose to run from plenum to pcv valve or is it a formed hose mine is so hard it needs replacement but cant find one the mustang sites have a hose that runs same route would that work thank you

Thanks for you quick reply ... I will look for it tomorrow.
I was expecting it to be on one of the valve covers ... good thing I did
not take up auto machanics as a career, huh!
Thanks Again,
Bob

I still have a problem ... I can't find the PCV valve!
This engine has a lot of stuff on top.
Do I have to take off something to get to it???

Here's a link with pictures taken of an engine removed from the car. It should help.
