Won't Ford change it at 60K for free?
I took my '95 4-cyl in for the cooling fan recall work, and it was close to 60k so I asked them to also change the PCV valve while they had it, since the owners manual implies they will do it for free.
I was told, yeah, they'll do it for free, so long as you are paying them to do the 60,000 mile maintenance service.....
That doesn't really sound free anymore, does it?
So I'll be groping around for mine sometime soon, let you know if I find it.
