I have been wondering as to why the tin on the front and top of the 2.8 engine? It seems to me that covering up the cooling fins would make the little engine run hotter. I don't know if this engine can generate enough heat to cause safety concerns in relation to the fuel tank , thus the tin pan between the two , or some other reasoning unbeknownst to me? Front piece really is a mystery? Any input would be most welcome to me. Always looking for answers.
