An oil leak is rarely a random event; it is the end point of a sequence involving stress, wear, or chemical breakdown within your engine. Additionally, using an oil filter that is too small or incompatible with the engine’s capacity can lead to poor filtration and increased internal pressure.
Understanding What Causes Oil Leaks in Your Vehicle
Rear Main Seal: This seal prevents oil from leaking where the crankshaft exits the engine block. Engine Wear and the Crankshaft Beyond immediate component failure, the general wear of the engine contributes to what causes oil leaks.
Pressure and the Oil Filter Oil pressure is essential for lubrication, but excessive pressure can create the conditions for leaks. If the crankshaft journals become scratched or worn, or if the bearings themselves are worn, the gap widens.
Common Causes of Oil Leaks and How to Save Time and Money
Over time, the constant exposure to high temperatures, engine vibration, and aging materials causes these seals to harden, crack, or simply degrade. These components act as barriers, preventing pressurized oil from escaping into areas where it does not belong.
