This is another topology discussion by Polish 3D artist Michal Kalisz. It's a lot about efficiently blending cylindrical forms into curved surfaces. You can almost sum it up in one image but I recommend actually reading the article Tools and Tips for Hard Surface Modeling in Blender 2.8 . It was posted 3/19/20 . I wanted to post about it sooner but I lost track of it for a while and had some trouble finding it again.

There are embedded videos. It's worth a read and the engine models look great by themselves.
