Is Oil Seal Leakage Serious?

Automobile oil seal leakage does affect the engine, and severe cases may lead to internal engine damage. If you notice a severe crankshaft rear oil seal leak while driving, immediately add some engine oil to the crankcase and quickly drive the vehicle to the nearest repair station for servicing. Causes of Crankshaft Oil Seal Leakage: The crankshaft oil seal may loosen or even fall off after some time if non-petroleum-based lubricants were not used during the installation process. If the parallelism between the rear oil seal mounting surface and the rear oil seal seat does not meet the assembly drawing specifications, the oil seal lip may deform unevenly under stress, leading to distortion over time. Additionally, prolonged engine use can cause natural aging of the rear oil seal, resulting in cracks at the lip and subsequent oil leakage. Solutions: Upon reaching a repair facility, if replacement parts are available, promptly replace the crankshaft rear oil seal. However, if spare parts are unavailable, you can remove the last crankshaft main bearing cap, carefully extract the graphite-asbestos strip from it, and place a layer of asbestos string coated with butter flat into the oil seal groove. Then, reposition the graphite-asbestos strip over the asbestos string as originally placed. This temporary fix may allow for short-term usage.

Oil seal leakage is no small matter. Having worked in the automotive industry for over twenty years, I've seen it all too often. The most immediate danger is oil dripping onto the ground, causing people to slip and fall, which can happen in parking lots or even your own garage. More seriously, oil leakage can lead to insufficient lubrication in the engine or transmission, increasing friction between components, causing overheating and damage, or even leading to a breakdown and accidents on the road. Once, a friend's old car had an oil leak that wasn't repaired in time, resulting in the engine completely seizing up—it took half a day just to get it towed. Such hazards don't just damage the car; they also pose a threat to personal safety. That's why I recommend that as soon as you notice oil stains on the ground or smell oil, you should immediately take your car to a professional shop to check and replace the oil seal. Make it a habit during regular maintenance to quickly inspect the condition of the oil seal—it can save a lot of trouble. Addressing oil leaks early is straightforward, but delaying repairs can cause costs to double. Safety first—don't take it lightly.

Oil seal leaks can cause significant impacts. I recently dealt with this issue myself, and it was both costly and time-consuming. Oil loss means you have to frequently refuel or top up engine oil, increasing monthly expenses on lubricants. The leaked oil also stains the garage floor, making cleanup messy and laborious. Ignoring it can worsen the problem—for instance, engine oil starvation leads to severe wear, potentially resulting in repair bills exceeding thousands, making early minor part replacements more economical. Last time, I overlooked a minor leak, which damaged the transmission, forcing me to replace it for over a thousand dollars. Now, I proactively check oil seal conditions during maintenance and replace them promptly to save money, avoid headaches, and preserve the car's lifespan. Remember to wear gloves during DIY work—oil stains are tough to clean. Leaks aren’t just troublesome; they severely drag down overall vehicle performance.

Oil seal leakage definitely has negative impacts, and what concerns me the most is the environmental damage it causes. Oil dripping on the ground, if not cleaned up, can be washed into the soil or waterways by rainwater, polluting the natural environment and harming small animals and plants. Oil stains in your own yard are also difficult to remove completely and can produce unpleasant odors. My car once had an oil leakage issue, which caused poor lubrication in engine or transmission components, reducing their lifespan. That's why I immediately take my car to the repair shop whenever I spot oil stains, to prevent further contamination. Regular checks on the oil seal's condition are crucial to prevent unexpected leaks. From an environmental perspective, every car owner has the responsibility to maintain their vehicle properly to reduce waste and emissions. Ignoring an oil leak is a small problem that can turn into a big headache.
