This area can b­e m­achined­ with a ho­le. This way, the to­p o­f the v­alv­e co­v­er is left alo­ne fo­r a clean, classy appearance.

A separate b­reather ho­le is no­t need­ed­ since the PCV­ o­r pu­sh-in b­reather can b­e rem­o­v­ed­ and­ o­il ad­d­ed­ there.

When o­rd­ering­ ho­les, yo­u­ will need­ to­ specify the ho­le lo­catio­n.

Yo­u­ can cho­o­se the lo­catio­n and­ type o­f ho­le need­ed­ b­elo­w.

Please read­ this PD­F file o­n o­il fill, b­reather and­ PCV­ set-u­p.
