The second pattern occurs when the preliminary filtration assembly becomes clogged, leading to poor oil flow, or when the oil temperature is low, causing poor flow. In this case, the oil enters a redundant filtration mechanism through a hole in the top ring cover. This redundant filtration mechanism provides redundant filtration, preventing the filter element from gradually clogging and resulting in poor oil filtration.
