I noticed that the car overheated. Stopped driving it and looked at it and saw that oil was mixed in the coolant reservoir, and heard a wining, screaching noise. 3 months ago I had the timing cover gasket changed, water pump installed and oil pan gasket, also a radiator installed. Help, What could be causing this???

Sounds like blown head gasket. That may have caused the water pump and radiator to leak as it may have been pressurizing the cooling system prior to the coolant getting into the oil at another breach in the gasket.
