No automotive engine has an oil overflow! you'd have to put 15-20 liters in it to see it over flow only then the engine would not turn over. even 1 liter over full will cause an extreme loss of power as the crank passing thru the oil robs the engine of power.
pressure wash the engine all over then run it and look for leaks, oil always runs down hill, for example I've seen engines that the customer was told need oil pan gaskets and valvecover gaskets....always fix the higher leak first, then wash the motor and re-check for leaks,
drips can come from (especially after doing a oil change)
1. drain plug loose or missing/damaged washer
2. oil filter too lose or faulty(leaks at seams)
3. hoses that go to alternator for vacuum pump
4. valve cover gasket
5. front main/cam seals
6. rear main
7. oil pressure switch
8. turbo return/pressure lines/tubing
