Part 3/5:
The oil that Hank extracted from the pump is described as being nasty and water-like, transitioning from a previously yellow color to a current muddy yellow and cloudy appearance. This color change, along with the presence of particulates, indicates possible chemical degradation or contamination of the oil, raising questions about the longevity and reliability of the pump.
Implications of Chemical Changes
Hank's observations lead him to ponder the broader implications of the chemical processes occurring within the vacuum system. As the oil chemically changes, it can potentially impact the pump's performance, leading to a variety of unknown outcomes. He emphasizes the need to investigate what is mixing with the oil and how it affects the pump's operation.
