This is a billet aluminum valve cover cap with PCV for the specialty competition valve covers you will find in my listings, designed to replace the solid valve cover plugs that come standard with the competition valve covers we sell. 

If your engine needs positive crankcase ventilation and not a closed system, this is what you need! If you are purchasing valve covers from me, please make me aware via ebay message before purchasing and I will work a deal for you.

What you were purchasing:

1) Billet aluminum valve cover cap

1) Billet aluminum PCV valve

Again please note: these are screw in billet valve cover accessories for the competition line of valve covers I sell, and they will not work to replace the original twist-lock style.
