Thanks for jumping in and yes it is the shaft with the front sprocket. I doubt it is bent as the cover always slides on, but anything is possible and I will check it. I have a toolkit similar to the Admiral's, but didn't use it to replace seals or install side cover. Remember it only leaks when the motor is running, WOT most of the time and you can't see anything when at idle. It is pushing enough oil now that it will drip off the swing arm.... The chain likes it, but the driveway does not.... I am going to take the skid plate off and try and get a closer look. Could a tight valve lash possibly cause blow by and cause breather problems? Anyway thanks again.
