I have developed what looks like a very minor coolant leak which appears as a few drips on the floor pretty much under the area of the oil filter housing. Only really leaks as the car cools down after running, nothing when car is running. Had a look from the top and also looks damp around the area where the oil dip stick enters the engine? Not sure this is connected. Any ideas before I haul myself under the car for a good look, only changed the oil a few weeks back and didn't notice anything then.
