Vacuum Leak Risk with leak severity rating of 18 score: a worked example

What does the result look like when leak severity rating reaches 18 score? The full calculation is worked below with real intermediate numbers. prioritizing leak checks before infusion or cure

The inputs for this scenario

  • Leak severity rating: 18 score (raised for this scenario; the documented default is 7)
  • Leak occurrence likelihood rating: 5 score (unchanged)
  • Leak detection difficulty rating: 4 score (unchanged)

Working through the calculation

  • Applying the documented formula (Vacuum Leak Risk = vacuum leak severity score × vacuum leak occurrence score × vacuum leak detection difficulty score) to the inputs above produces each figure below.
  • At this operating point the engine returns 9.95 score for vacuum leak risk score, the number this scenario is built around.
  • At this operating point the engine returns 18 score for vacuum leak severity score.
  • At this operating point the engine returns 5 score for vacuum leak occurrence score.
  • At this operating point the engine returns 4 score for vacuum leak detection difficulty score.

How this compares with the baseline

  • Against the tool's baseline example, where leak severity rating sits at 7 score and the headline result is 5.55 score, this scenario comes in 79.28% above the baseline at 9.95 score.
  • A figure at this level is achievable when leak severity rating is genuinely sustained, not just peaked for a shift. The score is only as good as the ratings; multiplication makes it sensitive to scale calibration, and equal scores can mask very different real-world consequences, so treat it as a ranking aid rather than an absolute hazard measure.
