I was changing the oil and plugs in the '93 Accord today only to find the plugs for cylinders 1 and 4 smothered in oil. The car has 180k miles on it and has already had the valve cover gasket done. Any ideas as to what else may be the problem?
Oily coating caused by poor oil control. Oil is leaking past worn valve guides, piston rings, or on some race engines a possible intake gasket leak and then entering the combustion chamber.
Check for worn valve guides (NEVER knurl valve guides), intake gasket sealing alignment, as well as worn cylinder walls and piston rings. A leak down test is a good place to start for what is causing this.

Blah blah blah!
It's pretty easy to #$($( up the gasket on those sewing machine motors... Since the whole kaboodle is <$20, I'd definitely replace it again before losing any sleep.

Huh? I'm confused. What does the valve cover gasket have to do with the plugs? Are you sure it's oil, and not carbon build up? I would do a leak-down and see if those two cylinders are leaking more than the others. If not, rings are ok. Then I'd put a new set of plugs in and drive it for a week and check them again. My guess it's valve guides, but then I know nothing about Hon-duh's......
Depending on the Hon-Duh motor it could have those silly little plugs down inside holes on the valve cover like the Miata does... which means if the valve cover gasket leaks, oil could go down into the hole and screw up the plug wires and short the spark to ground.... Just like on the Miata.

How old were the plugs?? Does it burn a lot of oil??
