I searched a few threads and may have found my cracked valley pan culprit. During initial break-in just running in the garage by dipstick blew out and i found that the PVC valve was blocked. After this i installed a new pvc valve and put a breather on the opposite valve cover.
It must have pressured up enough to crack the valley pan slightly and then just got worse. What'd ya think? Am i out to lunch on this hypothesis?
Here's a couple of good threads i found in regards to valley pans.
