How do replace a PCV on a ford 3.8 l engine?

It is on the right valve cover near the rear of the engine. On mustangs, and other rear wheel cars it is pretty easy, harder on front wheel drive cars like taurus, but possible, nearly impossible on a minivan because it is so hard to get too. If you can get to it , it is very easy to replace, simply pull the old one out of its grommet and replace with the new one. Be sure to check the grommet for cracks that may leak.
