What is that cap I have circled in blue for? What do you pour into it? Also, what is that region above the engine I have shaded in green? What does it do?

Answer 1

The component circled in rd looks like a circuit fuse for a stereo amp.

The green shaded component is the upper intake plenum, likely a dual runner design, providing better air velocity, sometimes refered to as tuned intake runners, provide for better performance through out the RPM range of the engine.

The blue circled cap is the radiator pressure cap, engine coolant/ antifreeze is retained under pressure for the engine cooling system, only remove when cool, for safety.

Answer 2

all pea soup to me

Answer 3

couldnt see the red circle. the blue circle is for putting antifreeze in. the green is fuel injection ports. thats how ur car gets gas to the spark plugs.(hope u know what that is.)
