Check the oil level, valve cover gasket, and PCV valve first, since oil near the injectors is most likely from an overfilled crankcase or a failed gasket. If those are sound, have a technician inspect for worn valve seals or piston rings, and account for turbo complications if the car is turbocharged.
The owner of a 1992 Eagle Talon with 164,000 km says it recently began blowing blue smoke only when accelerating and found oil near the injectors. The expert explains that blue smoke has several causes and that oil at the injectors is most likely from a valve cover gasket leak due to overfilling or a rotten gasket, or from a failed PCV valve. Those simple items should be checked first; with this mileage, worn valve seals or piston rings are also possible and need a skilled technician, especially if the car is turbocharged.
