2014 S60 T5 Oil Leak

[Biggertuna]

Recently purchased a 2014 S60 T5 (155K miles) and discovered a minor oil leak. By minor, I see a little drops on the ground after a few days.

Would anyone be able to provide some guidance as to what might be the issue?

Here's what I've done to date:
1. Removed engine and timing belt cover. Discovered oil on the intake and exhaust camshaft sprockets. I also found oil on the timing belt. Perhaps the crankshaft seals are worn? I did find some oil near the oil fill (guy claims he did his own oil changes), but I don't think he could have spilled that much.
2. Checked for whistling and excessive suction from the oil fill to see if could be a PCV issue. No whistling and I wouldn't consider the suction excessive.

I do need to replace the brakes so I plan on taking off the splash shield on the passenger side to get a different view.

Any idea what else I should check? Many thanks for the help.

Suggestion is to clean the entire area and then look for the leak. Color of oil will look different in photos so can't tell it's fresh, fresh mixed with old or has been leaking for sometime. It's guess work unless it's a known problem particular to the 14 S60.

Closing out this thread. Cleaned up the area and it took about 3 weeks to notice oil on the driveway again.
Turns out the cam seals and sprockets needed replacing.
Had the shop also replace the drive belt tensioner as oil had leaked onto it.
Additionally had a leak in oil filter housing.
Here's to hoping the car lasts another 100K miles.
