Question about 1993 Toyota Corolla
If the oil was still wet it probably wasn't coming from inside the combustion chamber. Oil in the combustion chamber would show up on the plugs as white ash (usually). It has been my experience with those toyota motors that the oil comes from deteriorating o-rings that seal the valve cover to the spark plug tubes. They're not very difficult to replace. Remove the valve cover (you'll need a VC gasket) and there are 4 big holes in it that fit over the spark plug tubes, which you should now see sticking up out of the head. Replace the o-rings around them and you should have no more oilly plugs. I don't think this really affects the performance, but I can see where it would cause plug wires to fail prematurely.
