Getting really bummed. Took the engine apart and put rings in it again. Still smoking. Drive around the block and when I return I drive into the cloud of smoke it left behind.
I'm standing there completly out of ideas. My wife walks up and says, 'How's it going?'. I said take a look and started the engine. She took one look and exclaimed, "Yikes that thing needs some serious pollution control equipment."
Something clicked in my mind. I reached under the hood and disconnected the PCV hose. PROBLEM SOLVED! It had been sucking oil directly into the intake manifold from the oil pan via the failed PCV system.
