Note 1:

The RB PCV Screw-On Cap comes pre-equipped with a new O-ring and during installation it helps to coat these with a little bit of clean engine oil while threading into place.

Note 2:

We are not responsible for over tightening this cap and breaking your valve cover! Please use care to not over tighten the cap!

The RB PCV Valve does not come with the RB Screw-on Cap as pictured. The picture is simply to illustrate how the RB Cap interfaces with the RB PCV Valve. You will need to order the RB PCV Valve itself as a separate item in order to receive it.
