Ford Expedition engine failure due to oil pump, main bearings, or timing chain tensioner issues with metal flakes in oil and no oil pressure on Ford Expedition

Some Ford Expedition owners report experiencing engine issues characterized by metal flakes in the oil and a loss of oil pressure. These problems may indicate serious concerns, such as spun bearings or worn-out components, especially when accompanied by a knocking sound. Additionally, a ticking noise could suggest insufficient oil flow, leading to potential engine damage. Common causes for metal shavings in the oil include worn bearings or oiling problems, with copper shavings often pointing to bad rod or main bearings. If the metal flakes are aluminum, they may originate from pistons, a faulty oil pump, or worn camshafts. Moreover, sudden drops in oil pressure after acceleration can signal underlying lubrication or oil circulation issues. It is crucial for owners to address these potential causes promptly to prevent further damage and ensure the engine's longevity and performance.
