Just called the Summit Racing hotline and the tech suggest I install Moroso breather Grommets. They have a slit in them to allow air to enter but keep the
oil from going back up the tube. Picture and description below:
"Universal, rubber, black, fits 1.22 in. diameter holes, integral baffle, breather grommets
These
oil resistant rubber grommets have a built-in baffle to control
oil. They're designed for use with valve covers that do not have an oil control baffle system. They are sold two per package and will fit all valve covers with a 1.22 in. diameter hole."
Cost: $4.95 for a pair.!!!!
