If you find an issue with the o-ring be it twisted, cut or missing then you might want to decide if you want to replace the oil pump seal. It is a little tricky as you have to drive it in with the lip going against the grain. I always cringe when I have to do this as I tend to have more issues putting them in when I face that type of situation. Of course if there is a stream or washed clean below the seal you have no choice. Just cross your fingers and be careful.
Worked on the "big rigs" for 45 years now just riding my Wing whenever I can. Gets cold in Wisconsin.
