(Sorry in advance for all the words).'90 K75s, 103K miles (about 60K on the engine). I changed the transmission oil about 6 mos ago but hadn't ridden it since - about a month ago I found a little puddle of what sure seemed to be trans oil (under the drain hole that's at the bottom of the trans). For the first time I had filled it with Amsoil severe gear 75W-90 so I thought maybe that had something to do with it. So I pulled the transmission and it appears that there is some leakage from the front cover of the transmission (not the input/output shaft seals or the clutch actuator boot). So i plan to re-gasket that cover. However, there was evidence of oil on the inside of the housing that surrounds the clutch so I figured since I was in it this far I would pull out the clutch which I did (friction disk/pressure plate clean, about 5.0 mm friction disk thickness). When I removed the big nut that holds the clutch housing I had trouble pulling the housing out and (likely unwisely) used a slide hammer with a hook to try to get it out when I realized that rubber/viton/whatever O-ring was holding it in. So - removed the O ring and the clutch housing and now there is a steady drip of motor oil coming from where the driveshaft exits - about 4oz since I pulled the clutch housing/O-ring. Sooo...is that dripping to be expected when the O-ring comes out or is something else going on?
