91 Accord Oil Leak (drip)
 

I have a 91 Accord that has a slight oil leak. It is dripping at the
oil pan, driver side corner, nearest to the firewall. It is obivously
coming off the mid-section of the engie, below the head. Any idea
where the oil is coming from? It leaks about 1 liter every 4 weeks,
but I'm getting tired of the mess under the car everytime and
everywhere I park it. Oil sensor?
