If you are getting oil down in the spark plug tubes, then you need to replace the valve cover gaskets and spark plug wires as well as the spark plug. The oil in the spark plug tubes will soak through the rubber boot of the plug wires and short out the spark to the side walls of he spark plug tubes. You can not clean the spark plug boots and keep them from arcing out so they must be replaced. You will also want to clean the spark plug tubes out by spraying Gumout carb cleaner into the tubes with the spark plugs out to clean out any oil that may be clinging to the spark plug tubes.

Now for the coolant leak, do you ever see any coolant on the ground after the car has been driven?
