So: I am waaay too dyslexic to be on this forum..... the actual intent was to indicate that zero consumption is a myth, the oil is being added to by the things you indicate above. Quick test would be an analysis.
The valve system leaks both ways, oil to cylinder, combustion products back. Unless you are running sealing style rings, there is a huge leak down at the gap, particularly when the gaps align. I have not experienced a sloppy head gasket, never owned an aluminum block motor except for VW.
