PCV valve size (diameter)?
« on: September 05, 2016, 07:01:02 pm »
Would anyone happen to know the diameter of a stock SBC pcv valve?    i need a push in type breather, but i'm not sure what size to get.

This is a stock, run-of the-mill, SBC pcv valve size hole.

Yeah, 1.20"/1.25" sounds about right but just trying to make absolutely sure.
