    Oil in intake manifold. 2000 200hp opti DFI

    0t076690 2000 200hp optimax 290hrs.

    Found oil leaking out of intake, took intake off and found a good amount of oil at
    the bottom. Checked my reed valves.They all looked ok. The engine is running a little
    rough at idle. Was wondering if the oil in the intake is normal or if
    its time for new reed valves? Any help would be greatly appreciated.


    Thank you,

    Would be very concerned if there were not puddled oil (especially after it had been idling).
