Hello, first of all I want to tell you guys thanks for accepting me here because im new, and also i am very uneducated in the mechanics of a car, i only know the basics, so i hope i can be educated.

This is a 2006 v6 4runner with 4WD. I inherited from my mother who changed her car. I've used it for a couple of months and now looking in the engine bay i found a lot of oil in the left bank of cylinders (looking from the front). I started to follow but i cant realize where it is from, i dont have the knowledge. Then i crawled under the truck and saw even more. Everywhere where i found oil is in the pictures. I found it weird that in the right bank there was no leaks. Also, the idle is perfect, always in 500rpm and solid, it doesnt move.

On another note i also found something formed up, which could also be a leak. I think is in relation to the fuel lines/pump. Its also in the pictures.

I would like to know what are your opinions on this, what do you think could've caused this? Should i do something? should i take it to a workshop? Should i keep driving it normally?

** The truck has 100,000 miles**

Thank you very much before hand.
