What Causes Oil Filter Leakage?
2 Answers
The causes of oil filter leakage are: 1. Aging or deformation of the rubber sealing ring on the oil filter base; 2. Loose transmission oil seal leading to overflow. The solutions for oil filter leakage are: 1. Replace the rubber sealing ring; 2. Ensure the oil level does not exceed the MAX mark when adding oil. The hazards of oil filter leakage include: 1. Internal engine damage; 2. Burning out piston and crankshaft components; 3. Complete engine failure. The working principle of an oil filter is that during engine operation, metal shavings, dust, carbon deposits oxidized at high temperatures, colloidal deposits, and water continuously mix with the lubricating oil. The function of the oil filter is to filter out mechanical impurities and colloids, maintaining the cleanliness of the lubricating oil.
I also encountered an oil filter leak issue recently, which was quite a headache. It happened shortly after installing a new filter – a few days of driving later, I noticed a small oil puddle under the parking spot. Upon closer inspection, oil was dripping from the filter base. Further examination revealed that the worker hadn't tightened it properly during installation, and the sealing ring was misaligned. Leaks commonly occur due to hardened or aged sealing rings, especially accelerated by summer heat, or from poor-quality filters with micro-cracks. High oil pressure can also force leaks, though this is rarer. The solution is straightforward: first clean around the filter, then gently wiggle it by hand to check for looseness. If a leak is found, don't delay—visit a professional shop for a replacement. Prevention tip: supervise the filter replacement process during each maintenance, opt for branded products, and tighten according to the manual's torque specifications. Don't underestimate oil leaks—low oil levels cause engine overheating, and severe cases can lead to piston scoring, costing thousands to repair. Now, I check the chassis myself every three months for peace of mind.
