oil leak

95 sebring 2.0 , 5sp. When ever I drive up a bumpy road or put it on blocks it leaks a lot of oil. It comes out of the clutch leaver on on the bell housing. It uses about a pint a week on the dip stick. The clutck works fine, not slipping. It its the rear seal how big a job is it to pull the engine? Is there anyting tricky about pulling the engine?

Thanks
