I'm unable to identify it but I'm sure 90% of the members here can help...
It's on the front rotor housing, close to the top spark plug. The liquid is now dried/sticky.

The picture I have is pretty bad but it was really the best I could do. I have my power steering half way removed and it was still in the way.

 

If it's not wet, or doesn't become wet again, it's not a leak. It's probably something that got dripped on the housing, then dried.

 

It's Probably you're knock sensor, I can see the black insulation melting off of it in you're picture.

 

Yep...It could also be anti-seize from the knock sensor or the spark plug.

 

i am extremely relieved.
thanks guys!\

and yes, the knock sensor doesn't look to be in the best shape.
