Guys, I pulled the plugs yesterday and they look clean (tan and dry), no signs of oil. Would you expect this from an engine that was burning a qt/100 miles? I will be scheduling a tear down with my engine builder early next week. But we're all a bit perplexed. It HAS to be burning it. There is a sooty residue at the exhause openings of my sidepipes, but the car doesn't smoke or hesitate. It runs smooth and idles fine. Does this make sense?
