Are your Neon/SRT4/PT Cruiser spark plugs drenched in oil? If your spark plug tube well seals look like the photo above then its time to replace the valve cover gasket and spark plug tube well seals. If the problem is bad enough, oil can interfere with the spark plugs operation and make your car misfire!
This is a fairly straightforward job to do, takes about 30 minutes at most and can be done with a 8mm and 10mm socket.
