Where is the pcv valve located on a 1990 Ford F-150 351 5.8L 4wd?

Answer 1

Probably the same place that the pcv valve is located on my 1990 Lincoln town car with 302V8 and fuel injection(Rear middle of lower intake manifold.....can't see it because of upper plennum). If there is a metal screen under the pcv valve, you better remove it before it becomes clogged.......it WILL become clogged eventually!
