    Four beeps, Pause, Four Beeps, or FAST BEEPING?

    The earlier is low oil level, LATER (fast beeping) is either Water in Fuel, Loss of Spark on one or more cylinders, or Oil Pump Rotation Problem (warning).

    Use a timing light to watch for dropped spark. Oil pump is a little harder but you basically disconnect pump outlet and measure output over a specific amount of time But, best for you to get factory service manual for specifics. Best money you will ever spend.
