Totally agree. You need to make sure that absolutely no more oil gets into the intake and don't reconnect the PCV until you're sure. Once the cylinders are clean, you can try connecting but I'd only do so if absolutely minimal oil (preferably none) getting into the catch can.
I say "preferably none", because the catch can is really only there if you can't figure out the real problem.
