| With weep holes, its pre side console. Despite what has been posted here there are THREE o-rings. The upper two are for coolant, the lower one is for oil to keep oil off the lower coolant o-ring. The weep hole passage comes from the space between the two lower rings to let you know when either of the lower two o-rings fail. A weep is not considered failure, I think there was a service bulletin suggesting the weep holes be plugged to avoid nuisance complaints and premature replacement of the o-rings and sleeves. The later (side console) engines have three o-rings and no weep hole. I'm not in shape this week to search my service bulletins for that information.
