My stock stroke mild 360 build ;)

is that what potentially caused my leak?
Key word potentially, but yes, if the crankcase was otherwise sealed.
It shouldda blown the dipstick out, which is the weakest link. Rear main seal may have become distorted and leaked, but if still in place, may recover.
The intake leak would probably have leaked anyway.
At this point, I would pressurize the CC with no more than regulated 3psi, and find all the leak-points. Three psi on a two inch camplug is 9.4 pounds of force, probably not enough to blow the rear cam-plug out, at least mine have always stayed in.... your results may vary......
