What size is this?

[d-nice]

I want to buy a vent filter for the passenger side valve cover and needed to know the size that I need to get. I already purchased a K&N screw in but but didn't realize at the time that it was made to screw into the oil filler hole. Does anyone know the size of the inlet hole on the passenger side. I am thinking that it is 3/8 of an inch but not sure.

Thanks

Before you do this, do an advanced search for threads that I've posted in dealing with the PCV system, breathers and/or oil separators. There's a lot more involved than just putting a breather right there.

I have an catch can in the drivers side already and want to cut off any oil that may want to make its way into the intake.

The problem with putting a breather there is that youll be letting unmetered air into the motor, through the pcv system. Put a check valve in and leave the tube on the intake tract.
