Today a customer called concerned with a loud noise she was hearing in her car. The car then stalled several times on the way to our shop. This is what we heard when the car arrived.
This noise is not reassuring and indicates an internal engine failure. To help diagnose this we took the oil filter apart to see if there was any metal particles trapped in the filter element. The following pictures show what we found.
This is a significant amount of metal and shows a bearing failure within the engine. There are several parts with several bearings each within the engine, including the camshaft and crankshaft. These bearings separate the metal parts reducing friction and wear. The sound we hear in the video above is caused by the parts within the engine banging into each other as the bearings that separate them fail.
The oil filter's function is to remove the crud and metal that may be found within oil. By keeping these particles in the filter itself and not allowing them to flow throughout the motor we short circuit the failures that would otherwise occur and increase the longevity of the engine.
This particular vehicle had 220,000 miles on the engine, and its failure was not due to poor maintenance or abuse, but simply due to age.
