Whether the pump was "actually broken" or not is completely irrelevant. Passing it through a TSA scanner in contravention of directives by the manufacturer caused it to be decertified and replaced. If you have an extended warranty on your car that covers engine and drivetrain issues as long as the maintenance schedule is kept up, do you change the oil at 3500 miles as per the manufacturers directives, or do you save the $30ish in the short term and only change the oil every 7500 miles? Your experience would tell you that no issues will result from waiting to change the oil, but doing so voids the warranty... and in the event that your experience proves incorrect, you now have an expensive lesson. The difference here is that trusting your invalid "experience" puts a lot more at risk than a seized engine.
