How to Prevent Car Oil Leakage Failures?

Preventing car oil leakage failures involves the following methods: 1. Pay attention to the role of gaskets. The gaskets between stationary parts of the car serve as anti-leak seals; 2. All types of fastening nuts on the vehicle must be tightened to the specified torque. If too loose, the gasket won't be compressed tightly, leading to leakage; if too tight, it can cause the metal around the bolt hole to protrude or the threads to strip, resulting in oil leakage; 3. Replace failed oil seals promptly. Many moving parts on the vehicle may leak oil due to improper installation, misalignment between the shaft neck and the oil seal edge, or wobbling. Some oil seals may lose elasticity over time due to rubber aging; 4. Avoid blockage of check valves and vent valves. Blockage can cause the temperature inside the housing to rise, filling the space with oil vapor that cannot be discharged, increasing internal pressure, raising lubricant consumption, and shortening the replacement cycle. If the engine's ventilation system is blocked, it increases the piston's movement resistance, leading to higher fuel consumption.

When I first started driving, I didn't know these things either, but experience has taught me that preventing oil leaks starts with regular maintenance. Every time you go to the 4S shop for service, don't just change the oil—ask the technician to carefully inspect the chassis, fuel tank, and pipe connections. Aging seals are a major hazard and need to be replaced every few years, especially the oil seals near the engine. Don’t drive too aggressively on the road, and avoid bumpy sections that might loosen screws. Regularly check under your car for any oil stains—if you spot them early, deal with them promptly. When changing oil, choose certified brands and don’t skimp by using low-quality oil that could corrode components. In short, stay diligent with inspections and avoid laziness to save yourself big trouble.

As a young person who recently bought a car, the preventive methods I've learned are about developing good habits. Spend some time every week lying down to check if there are any oil stains under the chassis, focusing on areas near the oil pan and exhaust pipe. Don't delay oil changes—follow the manual and get a comprehensive check-up at a professional shop every 5,000 kilometers or so. Always park on level ground to reduce uneven stress and oil leaks. When washing the car, take the opportunity to wipe off any oil spots so leaks are easier to spot. Choosing the right oil is crucial—I stick with major-brand synthetic oils to reduce the risk of corrosion and leaks. These simple steps ensure safety and save money.

I'm an experienced auto mechanic, and preventing oil leaks relies on regularly replacing key components. Seals and gaskets harden and crack over time, so replacing them every two years is the safest bet. Oil pipe joints often loosen, so tighten them a turn with a wrench each month. Don't overlook the filter during oil changes—if it's clogged, it can easily cause leaks. Check for oil stains on the chassis during every maintenance session, with a focus on the transmission fluid level. Vehicles exposed to high temperatures or frequent bumps should be inspected promptly to avoid seal damage. Don't force old parts to keep working—replace them cleanly. These habits can significantly reduce roadside breakdowns.
