You have oil in the driver side spark plug cylinder of your 02 neon anyone know why?

In my case the actual spark plug tube came loose. Also the spark plug tube gaskets my be leaking.

AnswerBadly worn piston rings may cause this. AnswerCommon problem with these engines, actually a cheap fix by a dealership. The sleeves that lead down to the sparkplugs seem to come loose after time and the gaskets fail causing oil to form on the top of your sparkplugs. The early signs are a faint smell of oil when your car warms up but no sign of an oil leak. After a wile the oil will get between the plug wire and the plug itself causing the car to misfire and eventually short out the electronis. To avoid more problems I would recommend taking it to the dealer, where they will pull the valve cover and replace the gaskets and reset your valve cover.. that costs no more than $90-$150, at least when I had mine done at 172,000 miles on my 2001 R/T. The dealership should know about this problem if you describe it to them.
