Fluid systems - damage models?

The two layers are coming from the engine and possibly fuel tank, or both from different parts of the engine. Because they are in line with each other, the smoke looks "thicker" even though it's the same texture.

Cannot agree with this. In the 109 there are 3 distinct oil leak levels before full on fire.

As I described on the point 1, there is also the smoke coming under the cowling(seen from the cockpit) which is much lesser than what is coming under medium smoking, described in point 2. And to more separate the light smoking from the medium, the light one doesn't smudge the windscreen with oil.

But both create black smoke behind the a/c. These too are very distinct from each other. The light smoking stream doesn't dissipate in the same way as the medium smoke. The light smoke trail stays the same width when the a/c gets further, but the medium smoke starts to fan out, getting wider before fading away.

The heavy smoking is also distinct from the two lesser ones in the way it makes the puffs of smoke along with the stream of smoke, which is also a bit more darker and wider than in the medium smoking.

I think I have seen these in the Spit too, but I think the variation is much lesser. Usually they only go for the "medium" type. Cannot be sure though. Don't usually have so much time to analyze them so properly .. But one clear heavy smoker champion is the Mig.. shoot at the wing root with couple of 20mms and heavy smoke comes out, and very soon the thing is on fire
