No smoke to indicate burning oil and there is no evidence of a leak. PCV and breather are fine. Compression test numbers are consistant and all cylinders read between 168 and 175 psi. No loss of power. Car only has 43K miles. What could be the problem? The only thing I haven't done is a leak down test. Please help if you have any clue.

    Has it been on a lift to inspect for signs of leaks? Not all leaks show up on the driveway.
