I went out and bought a couple of ¾” ID grommets the parts stores had friday….they measure just over 1” OD….
Took the valve cover off for better access…..
Here is what I have….....can’t really make the hole bigger without making the lip needed for sealing unusable……I suppose I could machine the boss (from the inside) bigger, as long as the bottom of the machining would have a flat bottom, and make the sealing lip wider that way….but these covers are hard to find and if I screw it up well…LOL……Mancini appears to sell some grommets that are for cast covers and have a wider sealing groove…..but that seems like that would mean the grommet would then extend into the cover more and stick out on the other side, getting too close to the baffle. I could try and alter the baffle, but ……
But, upon trying the store bought grommets, I found that I can get them in…..
So, it seems the rubber will compress enough to work. Looking at it from the inside, it appears a little distorted due to the force fit…..but I got a socket with an OD of .746 and the socket fits in the grommet once installed….
The grommet is thick, but less than ¾” thick installed…..measuring about .703” from the outside of the grommet to the inside ….so plenty of space between the PCV valve and the baffle that will be there.
So assuming the adjustable valve is ¾” and doesn’t mind a tight fit, it should fit.
Tried uploading some pics, get an error.....
