On the older cars, they used to have a distirbutor at the spot where you are leaking engine oil. On the newer cars, because of dis, they put a dummy shaft with an "O" ring to block it. After a while, with age and heat the "O" ring gets hard and cracks and starts to leak.
The "O" ring will have to be replaced. It is a tidious job. The throtlebody, fuel lines will have to come off. The dummy shaft hold down has to come off. Replace shaft seal (O ring) with new seal. Lubricate it and drop it back in. lock it down. Replace throtlebody gasket. Top up oil. make sure there are no leaks after washing the area. Good Luck.
