Hey guys I've been fighting this water pump leak for a week now, I first thought it was the cover gasket so I replaced it. Same problem. Traced it back to water was actually coming out of the hole in the picture. Is there a screw that's supposed to go in there? I'm completely confused as to what this hole is used for.

I appreciate the help, If I’m not mistaken it’s just 2 oil seals on each side and a washer correct? 01 YZ250

Theres a bearing on the inside of the right side case. You have to pull it to get the seal out and the new one in.
