I just bought a 1994 Honda Accord Lx recently, and it has a slow oil drip coming from either the oil filter or somewhere above it.
I have already changed the filter twice, and made sure it was properly seated, and not double gasketed. I saw on some other forum posts for newer models that it was either the oil cooler o ring, or the oil pressure switch. I’m not sure where the o ring would be on this model since the fuel filter housing isn’t removable from what I can tell, and I believe the switch is farther up on the motor under the manifold. Any help would be greatly appreciated.

 

If it's the factory engine, you do not have an oil cooler so it would not be the oil cooler o-ring. It's more than likely the oil pressure switch. It's very common for them to leak with age. Oil will drip down directly onto the filter when they do.

 

I second Aradin, oil pressure switch.
