From how many places engine oil can leak?

I have a Daihatsu Charade (aka. Subaru Justy), engine oil is leaking from many places, and I guess I need to change a lot of gaskets and O rings. I know there is a distributor O ring and I can replace that, and I know about valve (or rocker) cover gasket, I'll buy that one as well, crankshaft is not leaking, but engine is almost covered in oil and there are always drops of oil at my parking slot.

Which other seals can be possibly leaking?From how many places engine oil can leak?
Oil pump gasket or seal,camshaft seal,oil pan gasket,oil pressure switch.Put a small dose of engine oil leak detection dye in to engine oil,use the car for a few days then use a UV light to pinpoint where the leak is.From how many places engine oil can leak?
If you see oil on top, change the rocker cover gaskets.



If the oil is on the bottom, change the oil pan gasket.



You might try tightening the transmission screws also.



Then wash the engine, and see it the location of the leak is more obvious.
You should wash his engine using liquid cleaners to ensure a source of the leaks, if the leak came from above the oil will flow down so contaminate the entire machine, and after his engine cleaner it will be easier to determine the source of the leaks.
rear main seals, cam shaft seals, oil filter o-ring, oil cooler (if equipped), head gasket, oil pan.
any where there is a oil gasket 100 of places start with valve cover which is on top oil runs down hill
