    Did the knocking start before you changed the oil?

    The 85's are known to have some crank failures....

    Was it ever run low on oil? and was the oil filter put back in the right way?

    Get a long screwdriver, stick the big end on your ear and place it around the running engine. You should be able to narrow down where the knocking is coming from.
