crankshaft oil seal that typically leaks is found behind the alternator flywheel inside the left side cover which should be clean and dry of any oil.. paper gasket is basically used to keep water from infiltrating into the left side cover as there is a weep channel cast into bottom of left cover that is open to the atmosphere..
