Engines 101 Question

I have a confession, Oppo. I am a total engine n00b.

I can tell you every single power and displacement statistic of just about every single car made in the last 20 years, I have a very good knowledge about the mechanical engineering theory underpinning how cars work. I've loved cars since I was trainspotting them on the road at 4 years old.

But I've never worked on an actual engine. I know, I know. The mob forms to the left.


So please, with a spirit of patience and tutelage, humor me here while I ask you some questions about my car's engine, the Audi 1.8L Turbo, below:

Fig 1: What I believe to be the intake manifold, as explained in Fig 2.

Fig 2: This is obviously the dipstick. To keep the plastic from melting, it seems to me it would have to be wedged between the intake manifold, not the exhaust.


Fig 3: However, this looks like the turbo to me. Hence my confusion, as the turbo is obviously part of the exhaust process, not intake.

Fig 4: This is the actual block, yes? This normally has that bullshit plastic cover on it.


Thanks for helping me learn and get more into engines, Oppo, seriously.

Have a picture of my dream car for your trouble - a B6 S4 Cabriolet.
