These oil cap are a direct fit for the LS engine family that are equipped with a 1-TAB Valve cover or filler tube. They WON’T fit the 2-TAB cover. They are CNC machined out of 6061-T6 Aluminum and the logo is laser etched.
They feature a 1/2 NPT threaded hole for venting excessive crankcase pressure. They seal using an o’ring (included) just like the oem application.
These vented cap can be used to install a catch can or in addition with your CCV system. It is suggested to use a 1/2″ NPT swivel 90* fitting (not included) so the caps can be removed with the line still attached. Plumbing is left to the end user. See installed picture in the listing on my own car.
