Question about 1991 Honda Accord
I have a 91 Honda accord and had the exact same problem you have . Your oil pressure sending unit is leaking. It is located directly above your oil filter and has a single wire connector connected to the end of it . Go to your local parts dealer and purchase a new oil sending unit for your Honda . Make sure you get the right sending unit by letting them know if you have an oil pressure light or an oil pressure gauge . Don't forget to remember to tell them that one very important piece of information . Also , when you install the new one don't overtighten it . Screwed in by hand until it's too hard to turn , then using your deep well socket tighten it 3/4 to one full turn further . Also , the threads should have a sealer already applied to them . If they don't , you can use a little black or red RTV silicone sealer before you install it . Be sure not to use too much it only takes a little bit . And make darn sure you don't get any silicone in that little hole at the end of the threads where it goes into the engine. Good Luck

Could be coming from the oil pump or even the valve cover gasket.That's about it for oil.I recently had a leak in the dipstick tube.Are you overheating?Do you have to add oil?If so,how much and how often? Thanks,Greg

If the leak is coming directly from above the oil filter it is more than likely the oil pressure switch is leaking. The seal around the Oil pressure switch could have gone bad and now it is leaking.
The oil pressure switch is located right above the the oil filter and above the cooling system cross pipe.

make sure they are tight
could be time for head gaskets
make sure the old gasket from the old filter came off the block sometimes they come off old filter and stick this causes a leak due to improper seal.
