I don't think a piece of plastic/Styrofoam just sitting on top of the block would cool anything. If anything, it would probably have the opposite effect.Re the engine cover and the so called, diaper ...
Is it possible that they serve as cooling air ducts, or at least that was the original intent?
Apparently, not enough to justify keeping the engine cover but the felt pan, cost them money and hassle for there to be no reason. Maybe as a splash guard for electronics?
Reason I ask, is that I mess around with old tractors and the change to aluminum engines, also brought engine shields that serve as cooling ducts.
