What should be the immediate action if metal particles are found in the engine oil filter?

Finding metal particles in the engine oil filter is a significant indication of potential engine wear or failure, and it necessitates prompt and appropriate action. Following the manufacturer's maintenance instructions is crucial because these guidelines are tailored to address specific situations and issues that might arise within the particular engine model you are working with.

Manufacturers typically provide detailed procedures to diagnose the problem, assess the extent of any potential damage, and recommend the necessary steps to ensure safety and reliability. This may include inspection of engine components, additional maintenance actions, or repairs that go beyond simply changing the oil filter. Following these instructions helps ensure that a thorough approach is taken and that no critical issues are overlooked, which could lead to more severe engine problems down the line.
