And one more question I saw an Audi standing, whose engine compartment looked “like licked”! I now have a few questions: 1. How do you get an engine including the lock carrier and the adjacent body parts soooo clean? So, how do you do that and with what means? 2. Is it better to keep an engine soo clean, because it then also runs better, you can see any liquid leaks faster and the engine simply does not rot so quickly? OR Is it better to keep the M otor to leave as it is, also with its over the years “collected” dirt and dust layer, which he then has now? Because by “cleaning” (specially natural) and cleaning fluids (water, cleaning agents, …) the cables and components may be attacked more or can have short circuits – than if you don’t clean it? For me personally a clean motor always makes a better impression, simply because I think that there is less dirt and wear in the engine d is in the engine compartment – imagining or is it really like that?? What do you think about it? Just tell every idea! I’m curious … Joe In the appendix a perfect example of a clean engine compartment, as I think!
