Any one who knows me knows I like what I like and want what I want.
On my 66 Barracuda I’m building I really wanted a “period correct “ pcv valve but wanted the aluminum style valve covers that were aftermarket but pretty darn close to 66’.
I had a set of M/T covers we all know and some love. First issue I had was the grommets are hard to come by and when all 4 holes in the valve covers were opened by “others” it’s really a pain.
I wanted the pcv to be original 66’ like the ones on my Formula S Barracuda I have at home.

I did not want the factory newer style sheet metal valve cover pcv valve style.

Simply put I would had used it but I could not find a proper grommet to fill the aluminum cover hole. It’s 1-1/2”id not the 1” id the grommet fits in. So after a few tries I found the breather can grommet will fit the hole and reduce it down to 1”id. But the weight of the hose made the smaller grommet pop out of the larger one.
I decided to make an adapter from steel. Only trouble is no one reduced down the size I need. Even welding a reducing bushing looked bad. I went to the local hardware store and found a copper “sweat style” reducing coupler. 1-1/4” x 3/4” and it fit perfectly. I’m only putting this out there because I know others also have had this issue and there was nothing on the board that I could find here or anywhere about this. Also note that the rubber grommet used is the standard breather valve cover grommet for any 72 and newer small block.
Hope this helps.
Joe
