Sounds like the head has to come off. The white smoke indicates a blown head gasket or possibly a crack in the head, & # 6 is not firing. If it were the rings there would be blue smoke constant ly. Pull the head off, send it out & have it checked for cracks & give it a valve job. Did you notice if it was losing any coolant?
