Hi I'm Kevin is there any way you can send a picture of rough location of leak to assist me with diagnosis ?when oil is added does engine running improve ? Was there any noise when engine initially lost power?
From the pictures I can see it looks most likely to be the filter housing that is leaking do not drive the car until the problem is fixed
If the filter housing is broken it will leak that amount of oil the housing is made of plastic and can crack If it is the filter housing that's cracked I would expect the part to be around $100 plus new oil filter and engine oil and around an hours labour.
It's possible it's in the same area it will be located up above the sump area but from memory I think that's at the back of the engine
No worries please rate my service and come back if you need anything else at all
Glad your sorted
