I had that issue with my Edlebrock intake and it seems that the new OEM intake is going to develop that same leak. The distributor, when the lock is tightened down, is depressed low enough that the seal no longer fills the hole in the intake. I don't know if moving the drive gear farther down the shaft or gluing about 1/4 inch of hex stock into the
oil pump drive port is the answer. Any suggestions?
