It should be located right on top of the valve cover, if not then it would be inline with about a 3/8" hose leading over to the intake manifold. There are not that many vacuum lines there, so it shouldn't be that hard to find. The PCV system utilizes a fixed orifice in the intake manifold. There is not a replaceable valve according to Alldata.
