2000 310/5.7s/B3s. My outdrive reservoir has been leaking drastically into the bilge. The reservoir is totally wet from the top down. I removed it, cleaned it, dried it, put it back on, refilled it, took it out for about 45 minutes, came back, almost totally empty. The bottle was covered with oil, starting at the top and dripping down. Removed the top and realized there is no o-ring. Would no o-ring cause the bottle to empty out? I attached a picture.
