With normal engine the crack will leak little oil due to negative pressure inside, and should not spray as this case. This engine at some points in the drive, the pressure inside the crankcase was up high, probably due to a bad CCV / catch can system.

If you vented the catch can then maybe no more high pressure to crack VC and spay oil.
I was also thinking positive crank case pressure under load to cause this, normally cracked covers cause lean condition
