Cam lobe wear, and 2 mystery leaks - can you help me?

I changed the oil today and decided to take some pics. I have eraser tip-sized droplets on my garage floor since the last oil change 5k ago. I also have buildup and a separate leak from the power steering pump coolant line (I believe). I took pics, maybe you can help me identify what these lines are and where the issue might lie?

Car is a 97 C230 with 108k. Every seal, even the head gasket, was replaced at 80k under Starmark.

I am going to attempt to attach pics.......

The PS line is gooier than it looks - I cleaned it off last oil change and it's sludged up and oozing again. The other "mystery" line is behind the oil filter housing and should be obvious. There is oil seepage coating the mystery line, and based on where the oil dropped to the undercarriage tray and then on to the floor, it appears to be riding down this line.

Oops forgot the cam issue!

Cam lobe looks a bit worn down and there are 2 horizontal scratch marks on it (of course this is the only one I can see without pulling the cover).

I have owned the car since 61k and have done 5k oil changes with Mobil 1, either 0w40 (dealer, maye twice) and 15w50 supersyn extended life all the rest.

This an issue?

As far as I can see the lobe looks fine. Cam lobes have a thin hardened outer layer, once this wears trough it will wear very fast. If you run your finger over the lobe it should feel smooth, without dents or sharp edges. If it is really worn the valves get noisy. The scratches may have some effect on wear if they are big enough to break the oil film on the lobe. For the moment I would not do anything about it, since replacing the cam makes no sense if it not to badly worn.

On that PS hose leak, replace the hose, they get bad and seep through. The hose is cheap, go buy some at the dealership and use the hose clamps to attach it. Easy job, common item to fail, but fix it before it bursts. Good luck and happy benzing.
