O.M.G what happened there i thought my engine was bad when i got it, yours makes mine look mint when i bought mine. 
War wounds, looks worse now 
can it get much worse than that, then again i bought a little nova for wife many years ago and whole engine bay plus engine was covered in oil, my wife took one look at it and said thats well f*cked her words exactly im not having that so she went and sat in the car as it had other problems aswell all minor, so me being me i haggled with the seller and bought for £500 went back to our car and said follow me home ive just bought the nova to her horror she said please say you havent afraid so, on way home i popped into a car spares shop and bought a can of foam gunk and a rocker cover gasket changed gasket went down to jet wash and jet washed engine, rocker cover was leaking for so long whole engine bay had oil on it but the oil protected car from rust and paintwork in engine bay was mint, when i returned home with nova wife could not believe the difference and loved it, i mopped the car as it was white had calibra wheels in my shed which i put on and wife had car for 4 years and never broke down on her, we sold it for £500 it was a lovely little car and for a 1.2 it well shifted.
moral of story having oil on outside of car can sometimes be a good thing if you know what your looking at, i knew if whole engine covered in oil must be comming from top so easy peesy rocker cover gasket what does wife know.
