What size hole in the restricted push rod ?
I have a set of Smith Brothers (1 800 367 1533) restricted flow pushrods in my L92 433 engine. Oriface is .040" diameter. They completely stopped the oil puking into the catch can on my road race car... Also, don't use a high volume oil pump as it just pushes more oil up to the rockers... These pushrods are available in any length every .050". I used 7.350" length on mine as my L92 heads are milled .020"...
