Any recommendations? Thanks Another question, what is the correct hole size for Magnum Valve Covers push in breathers? Mine measures 1.300. Thanks again
K&N makes nice clean-able breathers. And they make them with just about any size nipple you need. I think on my Edelbrock valve covers I used a 62-1120 on one side and a 62-1130 on the other side. But you can get grommets in just about any OD/ID you need also. Crankcase Vent Breather Filters | K&N
Where do you get grommets for Magnum Aluminum Valve covers, the material is .450 thick at grommet hole, the largest grommet grove I have seen is .250. Thanks
Sounds like Mopar should have spotfaced those PCV/breather areas to reduce the thickness. If they didn't supply grommets, I'm not sure what you are supposed to do. 1/4" thick is the max.
