Wayne,
There is a couple of areas of concern here!!
One, as mentioned before, low tension
oil rings will definetly lead to high
oil compsumption.
Two, how much rod side clearance is in the motor?
And how much bearing clearance?
Your other replies covered a lot of the reasons for
oil consumption!! Mainly the oil return-supply to the rockers, but if all this is OK, then check the oil rings and the rod side clearance!!
Also, My FEs DO NOT LEAK. Its really a simple percedure to keep them from leaking along with proper crankcase ventalation!!
