The seal for the front crankshaft goes in the Timing Cover and seals the front pulley. The rear seal is commonly called the rear main seal and prevents oil leaking all over your flywheel.

Front
The seal for the front crankshaft goes in the Timing Cover and seals the front pulley. So if you see any oil leaking around the front pulley, inspect this seal. It is commonly included in the timing cover gasket set or can be purchased by itself for a few dollars.
Also check the seal surface of the Crankshaft Pulley. In this case, the pulley was cracked, causing an oil leak:
