I take it you mean the spark plug holes. Is the oil being pushed out when running or did you just notice that there was oil there? If the oil was just there then it could be as simple as replacing the Valve Cover Gasket. If the oil is being pushed out then possibly a blow head gasket a cracked head or cracked block.
The Check Engine Light being on I suggest pulling codes.
What you are calling the fan light, is it a square with lines in and a fan in the middle? If it is then it is letting you know your coolant is low or possibly that the coolant sensor is malfunctioning.
The thermostat you say isn't working right. Why do you say that. And I quest it would also help to know which thermostat the engine or temp control?
