ZZ4 Valve Cover Breather
Got an out of the box ZZ4 crate and have been trying to get valve cover breathers for it.. Bought a couple sets 1 1/4" (which is pretty much stock) from what I have seen.. Even with the grommet plug out the hole in the valve cover is too small.. Anybody ran into similar problem? Wondering if I need to take them off and mill/bore out the hole for the breater to fit, or if there is some special breather that is smaller for these.. Have looked in multiple places but nothing is jumping out at me..
