By the way, valley full of liquid oil would be almost impossible...lack of the various baffel parts, though, will fill the valley with oil spray and thrown oil, different but very likely to result in both strange external leaks and increase oil burning from overwhelmed valve guides.
Nothing likely could pump liquid oil in great quantity up there, and valley could not hold liquid oil anyway without some very unusual plugging!
A 59 or earlier could have a collossal leak into valley via front regulator, but that would likely give about zero oil pressure and oil still could not fill the valley without odd plugging.
The baffles are intended to suppress excess vapor and thrown splashes of oil, which are plenty for major consequences.
