I've been down that road before lol. Something might have been made to fit the application but wanted to be able to drive that day instead of waiting for something to come in the mail.

I have the kit from Mancini - the punch out hole on the MP VC is 1". The grommets listed don't fit without more work. All of them and the FORD ones are 1.25" diameter at the groove and the groove depth is not enough for the boss. Machine shop cost $30 to fix one VC.

None of those fit the punch out correctly on the MP aluminum VCs.

MP discontinued the grommets before they quit casting the valve covers.

This little plug and grommet set bears the same part number as the original grommet, and searching for it specifically (with or without the P) should bring up at least a couple suppliers. The kit was $17 if I remember right (outrageous for two chunks of rubber) but the question of whether they'll fit is answered.

The biggest problem with aftermarket "Help Section" generic grommets is that the seating groove is too narrow to fit in the half inch thick knockout boss. (You can also cut the bottom off the plug to use a larger PCV valve if necessary.)

I hope this helps!

The knockout boss was way thicker than 1/2". Try more like 3/4"+. I'd be willing to bet that the grommets you show measure the same as the Phord ones do. 1.25" groove diameter and groove 1/2" depth. Those did not fit the VCs I have without machine work.

I wouldn't say "way thicker" than a half inch.

The grommet / plug set I posted WILL FIT. If it didn't, my own covers would leak and I'd have dozens of pissed off customers because these are the most repeated thing that have crossed my bench for almost 16 years.

The photo above is from my post about your very same question to Facebook fans and friends back in 2017. Yours is not a unique issue. Other manufacturers make the grommet, and thankfully stayed mainly true to Mopar's original part number.

P.S. no one will crucify you for spelling Ford properly here. We're mostly adults.

They will be here Sunday! Does anyone have a link for the PCV that fits these?

I have a set of Cal Custom valve covers. My buddy found an oil cap with the PCV valve attached to the top. I just installed another breather type cap on the other side. Both are twist on with gaskets. So far no issues.
