valve cover breathers
Im sure Ive asked this before but what size gromit fits on the pass side valve cover?
I still cant find a breather that fits, even performance shops dont know what to recommend.

Re: valve cover breathers
Doesn't matter if they're centerbolt or not, the grommet is 1 1/4", or more like 1.22" actually.
If you want to know what size the hole through the grommet is, they come in a variety of sizes. Just get whatever size you need to fit the breather you want. 1/2", 3/4" and 1" are all common.
