That would be your front crankshaft seal in most cases but there are a few gaskets around that area as well. If your going to replace the timing cover gaskets replace the crank seal as well.
Not a hard fix.
1. Remove drive belt and crankshaft pulley.
2. Then lock the crank at TDC using the flywheel or an 8mm drill bit, loosen the crank bolt and remove the crankshaft hub that sits behind the pulley. Once this is off you will see a round seal that sits in the lower timing cover.
3. Use a seal puller or screwdriver and carefully remove it. Clean the inner surface of the timing cover where the seal was.
4. Apply some oil or CRC to the outer diameter of the new seal and guide the seal in carefully. You can use a socket and hammer to gently tap the seal into place. Guide it in until the seal is flush with timing cover surface. Take note of this before removing the seal. Also the seal has a unique spring around the inside of the seal to help it seal against the walls of both the timing cover and the crank hub. That's why it is important to ensure you are careful when fitting it.
5. Then refit your crank hub and use a new crankshaft bolt (recommended). With the crank locked in place tighten the the hub with the new bolt. (Make sure it is tight).
6. Refit crankshaft pulley and drive belt.
