If this link works, it shows the different sizes of grommets. Both the same od, but different id for oil fill, breather, or pvc. It doesn’t know if it’s in a valve cover or a valley cover. https://www.summitracing.com/search/brand/moroso/part-type/valve-cover-grommets

Most pcf valves fit into a 3/4" hole unless they are in an enclosure of some kind. If it's just a pcv valve, then it's probably not going to fit that grommet. If in an enclosure, then it probably will fit that grommet. I've used Moroso 68772 for the 3/4" id. There might be others. I do remember that there were far fewer options for 3/4" id baffled grommets than there are for, I think, 1" id.

Those are usually designed for a 1 1/4" hole. However, there can be quite a difference from one grommet to another. Measure the diameter of the grommet with a caliper, use a hole saw which is about a size under the desired diameter and then use a dremel to fit it to the grommet. That way you avoid making the hole to big. If you use a 1 1/4" hole saw, it will be too big because hole saws are not extremely accurate cutting devices and the fact that the grommet may actually be a little smaller could make matters worse. Sorry for taking this Topic away from original Posting. Does the PCV fit in this Grommet once installed or am I going to need another smaller Grommet to fit inside this One? I haven't really checked it as I am not installing in yet.

I used the previous version of their grommet, looked more like what I’d call a “duck bill” on both a stock bird cover and a finned aluminum cover. Worked fine till I went to the hi volume/pressure oil pump. And the supercharger and cam, and started winging it past 5500 rpm. Then I started to suck oil in. I added a baffle in the aluminum cover, but I’m still using one of those grommets. They’re made to go in a valve cover, but there’s a lot of oil flying around in most of those, too. On a stock motor, I didn’t have a problem. RPM and boost complicated things. What Size Hole do I need to cut for this Grommet?
