An oil seal has two tasks: Keeping the lubricant in and keeping dirt and contaminants out of rotating components. This separation must be accomplished between surfaces in relative motion, usually a shaft or bearing inner ring and a housing. With correct installation, oil seals can also prevent seal leakage and maintain the lubricity of a bearing to ensure that the rotary shaft and its bearings remain fully functional.
Overall, black spark plugs are a common issue that can occur in internal combustion engines. It is important to regularly inspect and replace spark plugs to ensure optimal engine performance and prevent more serious issues down the line. By addressing the root causes of black spark plugs, such as a rich air-fuel mixture, oil leakage, and overheating, you can keep your engine running smoothly and efficiently.
