Before deciding to do anything with my oil leak, I decided to inspect the engine.
The pictures I took:
I suppose VCG is leaking. What about the large oil spot on the valve cover in the first pic? it is in the middle of the passenger side, right next to washer fluid fill. And how about the front of the engine, in the third pic?
Also checked the exposed head bolt (4th pic), is there any sign of snapping off soon?
