Aftermarket valve cover breather

[Sonny]

Can someone send me a link to the breather that fits these 318 mopar performance valve covers? I can't seem to get the right size. Thanks

Aftermarket will be just fine.

Most that I've seen, you just have to measure the diameter of the old one, or inside measurement of the grommet. Not too many listed as engine specific anymore.

Ya measure in grommet. Typically in millimeters. Then search summit or jegs etc, even ebay. The breather will be larger for a snug fit. For example i wanted custom billet looking ones to.match my fabricated aluminum valve covers on a 455 pontiac. The ones i got were 37 or 38mm. got grommets that size at pepboys, but they measure 35 or 36mm. I got alot of dripping out of the breathers though so if theres no oil baffle on the valve covers (can you see lifters in the hole or just metal?) get new grommets with the baffle built in.

Does it use the same twist on like my 383?
