Which risk increases when a diesel engine piston's oil scraper ring fails catastrophically?

💡 Explanation

When an oil scraper ring fails, excessive oil enters the combustion chamber because it bypasses seals causing incomplete combustion and soot formation which directly contaminates and rapidly degrades the catalytic converter. Therefore, catalytic converter contamination increases, rather than fire, bearing issues, or imbalance which arise from different independent failures.
