Engine damage?

Hello… something terrible happened to me today… I was with my father during the midday break, and somehow we got to control the oil at my Fiat (Tempra 1.9 TD) and fill up a little something… (but didn’t miss much! So I went back to work and in the evening still to my girlfriend (everything on the highway total distance about 150km – top speed 170 and in average 140-150 km/h) So why I tell you all this… Well, as I arrived at my girlfriend I noticed a strong oil smell after I got out of the car! Well, I just opened the bonnet for control and found out that we didn’t pull the lid for the oil inlet tight enough! Well, except that the whole engine block is full of oil and now stinks like the plague, about 1.65lt of oil was missing! (So I immediately measured the oil and it was still above the lower mark – so still on d) I’m sorry for the many questions, but I’m really worried about my favorite… Oh, my God, I’m sorry for the many questions, but I’m really worried about my favorite… Oh, I’m sorry for the many questions, but I’m really worried about my favorite. a when driving home (of course again with full oil level) I didn’t notice anything that he would have less power or anything! Oh yes the engine has a little over 190,000 km down (only if that’s important!!) Thank you for every answer!
