Sounds like rings are stuffed. PCV will leak a bit of oil into the inlet, if it's gushing in either it's not draining properly from under the rocker cover back into the sump and/or broken or worn rings. I have seen people route their PCV back into their sump but with a second hose teed off of that back to the original position. Rough but it puts the oil back where it's supposed to be.

Remove the PCV hose from the rocker cover and run the engine to see if that's where the oil is coming from, giving it a bit of a rev. If it is, check compression and go from there.
