Without the plugs in it will turn over pretty fast, forcing the oil and any dust or anything out the hole. Oil is leaking into spark plug well Inspection Service. Oil leaking into the spark plug wells is an indictor of a fairly serious problem that should be inspected and repaired immediately. It is almost always due to a failing gasket or O-ring but can also be the result of a failing piston or worn valve guides. Remove all of the spark plugs, and using a squirt can, shoot about a tablespoon of engine oil into each spark plug hole. Once this is completed, gently rotate the engine BY HAND a few times to help re-coat the cylinder walls with oil and to make sure it actually turns over and doesn't have any other issues. When a spark plug well fills with oil, it means that the O-ring that seals the well to keep out oil and debris has deteriorated and started to leak. Although the leak can sometimes be fixed by tightening the valve cover bolts, more often than not the valve cover gasket and well seals will need to be replaced. So, before fixing the oil on spark plug, make sure you are equipped with the following tools: Valve cover gasket and O-ring spark plug tube seal. Power Handle. Spray cleaner (for oil) Pliers. Socket and spark plug socket. Ratchet and extension. Engine sealer. Screwdriver.
Bad piston rings will let combustion gases into the crankcase and engine oil into the cylinder. If the blowby gets real bad, the oil can foul your spark plug. In this case an easy, but a temporary fix is to install a spark plug anti-fouler. Bad spark plug tube seals are the most common cause of oil on your spark plug.
The average cost for a valve cover gasket replacement is between $248 and $321. Labor costs are estimated between $193 and $245 while parts are priced between $55 and $76. Estimate does not include taxes and fees.

Common signs of faulty spark plugs include slow acceleration, loss of power, poor fuel economy, engine misfires, and difficulty starting the car.
If you found oil has entered the spark plug tube galley then the oil may have shorted out all the coils and plug wires causing the engine no start. Once this is done then you may need to replace coils and or coil wires if they were damaged from the oil contamination.
Wet. A wet spark plug can be the result of the engine flooding. Flooding is what happens when you try to start the engine several times without it firing up. You can clean the spark plugs or you can just wait for them to dry out.
With the plugs in, wrap a rag around the end of a screw driver, spray rag with some carb cleaner, then wipe around the plug and get out as much gunk as possible. Then remove the plug and as Dennis recommended vacuum out any loose debris. Then get the rag and screwdriver in there again and keep cleaning until satisfied.
Symptoms of a Bad or Failing Valve Cover Gasket Burning oil smell. When a valve cover gasket is pinched, worn out or cracked, compressed oil from underneath the valve cover will find a way to escape. Valve cover is dirty and leaking oil. Engine is low on oil. Engine is running rough and causing misfires.
How to Get Water Out of a Spark Plug Well Open the hood of your vehicle. Remove the spark plug wire from the spark plug with the water around its well. Soak up as much water as possible out of the well with a clean piece of cloth. Vaporize as much water as possible by blowing hot air around the spark plug well using a hair dryer and let the well cool.
Problem Description The valve cover gaskets may leak oil into the spark plug wells, shorting out the spark plugs, causing a misfire, and illuminating the Check Engine Light. Commonly the spark plugs and ignition coils or wires will require replacement, along with resealing the valve cover to correct this concern.
Valve covers leaking is only going to cover the engine in oil. As long as you have enough oil, its not an issue. The overheating sounds like a pinhole leak, or the radiator is partially clogged. If you can, pull over when it gets hot and see if you can see any pinhole leaks spraying.
Wet spark plugs means the spark plugs are not firing. The spark plugs are coated with unburned gasoline, which allows the ignition voltage to short circuit to ground instead of jumping across the electrode gap normally. Wet fouled spark plugs can be caused by flooding the engine when attempting to start a cold engine.
If it allows a major airflow through the crankcase ventilation system, and other parts of that system are also compromised, then yes, it could. Especially in the days of the old PCV and vacuum line—sort of like when one pulls the valve off that line—the engine then leans out—and runs rough at idle.
