im burning oil like crazy i burned about 4 qts. in about an hours drive of not getting on it but interstate cruising. I did a compression test and leak down tested. On the number 1 cylnder it was 250, #2 was 230, #3 was 230, and #4 was 250. It also didnt leak. Now it smokes at idle and driving but not alot. My spark plugs are black but there wasnt any oil on them. Im also not burning coolant. Any help would be appreciated.
