I have the mopar performance big block cast valve covers with a twist on hole and knock out spot on each. I am installing a m/e Wagner Pcv valve in one of the twist on holes. It needs 3/4” id. Does anyone know which grommet with that id also has big enough diameter to seal twist on tang cutouts also. I read a review of Ford grommet M6892F working well on the mopar covers. but Not exactly sure of thickness of groove needed either, covers are an hour away so I can’t measure them right now but want to get parts ordered. Pcv will go on rear passenger side, this just pic of the actual cover for reference. Thank you

I have one those as well. Haven’t installed yet but, make sure it’s baffled under the valve. That’s why I haven’t installed yet. I’m gonna weld my baffle because I don’t want the screw heads on top. Using fabricated alloy valve covers. Also, I believe the MP have provisions for the baffle. You probably know all this but thought I’d through it out there. Here’s a diagram. They should have sent some paperwork if you bought new. Good luck and let me know how you like it.

Thanks for the info. I googled the part number and ended up on the m/e Wagner website. It says unavailable. I talked to them yesterday and no mention of this grommet. He did suggest the Ford part. I also found a post on FABO where someone used the Ford part on these covers with Wagner. I found one yesterday evening and is on the way. I’ll update how it fits.

make sure you deburr the hole or it will cut the grommet over time. ( learned it the hard way)
