    The oil is from blow by. which is being introduced from the pcv to the intake. If you want to help the issue, You could install a oil catch can.
    As an engine ages rings wear. letting blow by to occur.

    If it was the pcv, I would think you would be getting a higher idle. You could change it but I don’t believe its the issue.
    As for a compression test. I don’t know your engines spec’s. Ball park anything over 130 psi per cylinder, with no more
    than 10% between the highest and lowest cylinder readings.
