crankseal leaking?

[greatone]

i have vs clubby and was told my crankseal is leaking, is that the gearbox and does it take away some power?

no.... its at the rear of the engine.... its on the rear of the crankshaft.....if its bad oil can get into the clutch and make it slip if you got manual gearbox.... gearbox or engine will have to be removed to fix it....
