I found this leak or spill and I tried looking it up, found nothing
Please help?

Can't really tell, but it's most likely either the water pump or thermostat leaking. While you are in there replace both.

Is it Really? this is on the passenger side of the engine thought the thermostat was in the front of the engine?

I can't tell where the leak is in your pic.

You need to put an arrow on your picture to better describe the location. You also need to better define the fluid that you have discovered. Color, consistency (oily or watery), smell, etc. Without additional detail, we cannot assist or it would be a WAG.

I too, cannot see a leak.

However, if the red arrows point at the leaks, it's the expansion tank.
If the yellow arrows, the lower rad hose. The electrical sensor in the lower rad hose is the radiator outlet temp sensor used to control the electric auxillary fan in front of the rad and A/C condenser.

Get a white paper towel and clean some off. Also touch it and smell it. When engine cold wipe you hand under the vanos unit. Let us know what you find

Could be VCG leak or vanos leaking. Get a mirror and look. Maybe get brake cleaner and clean area and check it daily to confirm location of leak

Rub a clean paper towel under the edge of the VC rim. If it comes up oily, that's your leak: valve cover gasket.

see for the DIY fix. ~ $40 for the part. You may want to consider replacing your Vanos seals since you are half way there. Do a search for why.

That's where my VCG was leaking. Once that far repairing it I decided to also changed the VANOS seals.
