My new 1930 2-dr sedan

[David in San Antonio]

It appears that your car does not have the engine pans in place. These bridge the gap between the sides of the oil pan and the frame rails. They keep road dirt from flying up into the engine compartment and being sucked into the carb. Some people say they also help engine cooling. It seems that mechanics found them to be a pain in the neck when dropping and reinstalling the oil pan, so threw them on the scrap pile by the thousands. I figure if Henry Ford could save a dime or two by eliminating an unnecessary part he would have done it.
Something to think about.
