Massive oil leaks.

What I am not getting is that if there was enouh pressure to blow out the pan seals, then that was a signifcant amount of pressure, and if at anything more than cruise throttle, it is unlikely IMO that a PVC would compenste for THAT much crankcase pressure. OR, there is something not right in the intake area....intake not machined to match heads, etc. I think there is something else going on inside the engine that is not right.

And, we don't know how the owner treated the engine out of the installer's shop. It coulda just blown something due to a mistake in assembly or being overused too much, too soon. I doubt we will ever get any detail on that. Time to move on .....
