I heard of the part being replaced with a part off a ford 5.4 liter engine. I searched off the lightning f150 from 2003-04 to see if I could find anything. Are any of these the correct parts? Will they work on our s type r's? If so, which one would be the best tradeoff of performance to cost?

I thought that the STRs do not have a PCV valve, but rather a calibrated orifice from the driver's side valve cover. There is no valve to replace.

 

You're probably right. Anyhow, what's the part number? Most of the sites I checked didn't have the jag part listed. Also the ford part model would be awesome if anyone has it.
