Dan,
Based on your compression readings you are leaking badly from those two low
cylinders.
Compression at or under 125 should be looked at as a problem. As Tom
mentioned, rings are the probable culprit, though worn valve guides could
also be a problem. My van has roughly 215K mi and uses about a half quart
between 4000 mile oil changes. Since I rebuilt it last year, the compression
is perfect all around and most of the leaking oil is coming from the spent
crush gasket on the oil plug. That crush gasket is getting replaced this
weekend when I do my next oil change. I suspect I will not loose any
significant amount of oil between changes after that.
