2003 996 Oil consumption, continued

Engine

Vehicle Information: Model: 996 C4S; Year: 2003; Body Type: Coupe; Total Mileage: 34,000;

Greetings! Just an update on earlier posts with a little more data. Oil consumption is just below the 1.1qt per 600 miles where the dealer will take more action. I had been running 1 qt per 1500-1800 miles until winter, when it dropped and stayed down.I am working with my dealer to track down the high oil consumption. Car is a 3.6L 996; 2003; about 35K miles. Oil is Mobil1 0W40.So far, here is what I can say:Car seems to run fine . . .No drips at all.Quite a bit of soot above left exhaust. Almost small dry black droplets here and there. Much less on right.No oil in coolant.No smoke.Recently the dealer ran a compression test and a leakdown, both with good results. Compression values varied about 2% between cylinders (210 to 215), and leak down was only 1 to 2 % per cylinder.I have asked the service team about the AOS, but the absence of smoke makes them think the AOS is OK.Still under CPO, by the way. Any suggestions on futher testing? Thanks
