ok so im confused whos motor are we talking about is it your or his or both ...as for the pcv id have to see it but if its setup wrong it could be sucking oil via vacuum and filling the intake runners...if he used a good compressor and they were gapped properly they would have slid in easy with a few bumps of a wooden handle and also did he or you clock the rings properly so that the gaps would not line up and cause blow by
