Failed Engine Testing
This video demonstrates a simple, low-cost method to determine if an engine may need replacement, focusing on analyzing the oil filter. While extreme engine symptoms like loud noises, shaking, or parts visibly falling off clearly indicate a failing engine, milder symptoms like poor performance can be diagnosed using this approach.
The method involves removing and cutting open the oil filter to examine the filter media for debris and metallic particles. Using an oil filter cutting tool, the filter is opened, and its pleats are inspected for buildup. Visible solid matter, such as metallic flakes or residue, often suggests significant internal engine wear. Note, the "glitter" found in the oil and filter is typically metal debris originating from the engine's internal components.
Always use a clean workspace to lay out the filter and examine both the oil and debris carefully. The outer pleats of the filter hold the "dirty" oil, which should be inspected for significant buildup, while the inner pleats generally contain cleaner, filtered, oil. The distinction between these areas is critical for an accurate assessment.
This process is a practical, accessible diagnostic tool that avoids disassembling the engine. With basic tools available online, like a filter cutter, car owners can quickly determine if their engine is in poor condition. This is an important testing method when symptoms are mild, as it provides insight into potential engine damage before further failures occur. By focusing on metal debris and debris in the oil filter, you can identify serious engine issues, saving time and effort in diagnosing internal problems and dealing with stranded vehicles later on.
