I am not a tech but sold Johnson's for 30 years and know a little. I don't think the VRO pump is a serviceable part, so if you took it apart that may be part of the problem. It also acts as the fuel pump so if it is pumping more oil it should be pumping too much fuel also. There is a squeeze ball between the oil tank and the motor and you should never squeeze it, it is there only to pump oil up to the engine when it is new, or a new pump is put on, if you do squeeze it by mistake it pumps raw oil into the system. That would show up as oil in the carbs. The 2001 models are the last ones made by OMC before they filed bankruptcy in December or 2000 and I think some of the parts were questionable on the last few motors made. Good luck and let us know what you find with it.
