I've had to add 1/2 litre of oil to my car twice in the last 6 weeks. I have checked for blue/white smoke and for creamy residue and I'm not getting that at all. But today I noticed some wet oil around the entrance of the dip stick. There seems to be a splash of oil down the side of the engine above the belt and the floor of the car below the engine seems to have soil oil stains. Not sure how old the oil stains on the floor are, but if they are from a leak in my engine, it would seems to be close to the front/driver side of the car. There is also an oil stain on the step where my car front would park up to. Anything obvious here? Is it something I should have repaired, something I should keep an eye on while carrying some oil with me or should I be very concerned and think about changing? It's a 01 Cordoba 1.4 petrol. Cheers.
