Oil leak from passenger side of head

I tried looking around for this. Can someone tell me where the oil leak is coming from. Its seems to be from the thing between the upper radiator hose and the heater inlet hose. What is that? TIA

Looks to me that it might be your cam seal. If it is, then it should be an easy fix and nothing too big. Its a pretty common problem for most b18 engines. After you run your car for a little while, slide your finger under the cam seal with a paper towel. Im pretty sure the paper towel will be drenched in fresh oil cause those cam seals tend to crack or just get damaged over time. I may be wrong but I have an oil leak similar to that and that is my problem, maybe it could be the same for you too. Good luck!:salute:

just hose it down with brake clean. all clean and dry. then fire it up and watch where it starts leaking. there are many possibities in that area

Hey can someone tell me what the thing with the hex key in it is? It looks like the source of my leak.
