Got back from a little drive. Redid the leak down while the engine was the hottest I could get per say. I come up with 10% leakage this time. What do you think of 10%? Some feel it should be 5% on a good strong motor, engine broke in. (ours isn't though yet). The smoke wasn't too bad. Actually seemed to get less a bit by driving it a little bit harder than normal. I'll keep track of my qt per mile and see if it gets any better.
