Default 1997 Honda Accord Unusual Oil Leak?

I have a 1997 Honda Accord "Special Edition" (based on the LX model) 2.2 Liter 4 Cylinder Automatic two-door coupe.

My car has had an ongoing problem since I bought it - an ongoing internal engine oil leak. Two of the four cylinders collect large amounts of oil towards the bottom of the spark plug tubes, obviously causing the spark plugs to be covered in oil (with power loss noticeable, I'm sure this is causing them some trouble though they seem to be working). The tubes never fill with oil, it stays in the bottom and does not appear to come from the top. I can pull out the spark plugs and wipe everything clean *as possible* but it's back to the way it was after only one trip. The oil *IS* leaking out of the engine somehow as it is making the side of the engine towards the distributor cap oily, along with electrical connections in the area (I continue to wipe this).

My vehicle, according to the internet and products available for purchase, has "lower seals" which were never changed (something apparently unique to the year of my vehicle??). The valve cover gasket and UPPER tube seals were replaced two times - this did nothing for the issue. An expert Honda mechanic states to me that he has never heard of the lower seals and thinks repeating the gasket and upper seals would help but I don't know what to think. I have conflicting information.

Any advice???? Does anyone know of this/heard of this?

Not sure who your Honda expert is but he is 100% wrong. The lower seals are an o-ring that sits between your rocker arm assembly and the head. This is a common repair on all 90-97 accords. In 98 they changed to a solid steel tube that is pressfit into the head. Replacing the upper seals won't help if these are leaking. I'm on my phone at the moment but I'll upload some diagrams on my computer when I can.

Will is right - the lower seals are not all that uncommon. The upper seals leak more often but the lower ones (as he describes) are a real headache. If I'm not too disoriented they are part 19 in the first source.
