His OP was possible rear main seal leak and misfire. Although a plugged PCV would probably cause a catastrophic rear main leak dumping most of the oil, it wouldn't be a possible, you would know.
My vehicle is known to have issues with exhaust moisture and condensate buildup in the PCV system, especially when doing only short trips in the winter and freezing up blowing the rear main seal. I added a vented oil cap to allow for pressure to be released if that ever happens.
