SUMMARY
High temperatures on cast iron surfaces, particularly in exhaust headers, lead to the formation of craters due to accelerated corrosion. This phenomenon occurs when improper timing causes exhaust leaks, trapping heat between the cylinder head and the exhaust header. The elevated temperatures increase diffusion rates, significantly enhancing the corrosion process. Understanding this relationship is crucial for maintaining cast iron components in automotive applications.
