I replaced the engine to clutch seal and o-ring along with new clutch about 500 miles ago. However now I am getting oil migrating down the push rod shaft to center of clutch. When I took the boot off the push rod a lot of oil came out (1/2 to 3/4 cup). I understand there needs to be oil to lube bearing set at rear end of push rod, but should it be submerged? Is there a drain port back to tranny basin somewhere? I plan on replacing the push rod seal, but am concerned about of quantity of oil behind the boot! Any comments appreciated.
