Will the engine still burn oil after replacing the oil seal? There are many reasons for engine oil burning, and the specific factors are as follows: Carbon deposits in piston grooves: Carbon deposits accumulated in the piston grooves cause the piston rings to stick together, resulting in the piston rings being stuck and unable to fully seal. The "stuck" piston rings greatly reduce the oil scraping and sealing ability. In addition, sludge can also clog the oil return holes, preventing the oil from returning normally, leading to increased oil consumption. Wear between the piston and cylinder wall: Carbon deposits will further aggravate the wear between the piston and cylinder wall, causing excessive clearance and allowing oil to enter the combustion chamber. Aging of oil seals: Corrosion and aging of the valve oil seals result in poor sealing. Valve oil seals can be said to be the most prone to aging wear parts in the engine. Basically, cars that have traveled more than 100,000 kilometers have this problem.
Replacing the oil seal doesn't necessarily solve all oil burning issues, as I've experienced similar situations before. Oil burning can originate from multiple sources, such as worn piston rings, scratched cylinder walls, or leaking valve guide seals. If only the oil seal is replaced while ignoring wear in other components, oil consumption will still occur. Take my previous car as an example: after replacing the oil seal, oil consumption did decrease, but after a while, it started burning oil again. Later, it was discovered that the piston rings had aged. I recommend that after replacing the oil seal, you regularly check the oil level and engine condition—for example, checking for blue smoke from the exhaust pipe and measuring the oil level every 1,000 kilometers. If any issues are found, have a professional technician conduct a comprehensive diagnosis promptly to prevent minor problems from escalating. This can help you avoid costly major repairs in the future, ensure your car runs safely and efficiently, and extend the engine's lifespan.
I've driven several cars and encountered situations where oil consumption persisted even after replacing the oil seals. While replacing oil seals addresses common leakage points, oil burning isn't always solely caused by seal issues. For instance, worn piston rings or excessive engine wear can also allow oil to enter the combustion chamber. Think about it - as cars age, components naturally deteriorate, especially in high-mileage vehicles. I remember one time after replacing the seals, oil consumption improved for about a week but then recurred due to excessive carbon buildup affecting sealing performance. As a driver, I maintain regular service intervals, changing oil and filters every 5,000 kilometers while avoiding overloading the engine. If oil burning continues, it's wise to inspect other sealing components or consider an engine overhaul. Early detection and resolution not only saves money but also reduces emissions and environmental pollution. Don't delay addressing this issue, as prolonged neglect could damage the catalytic converter and significantly increase repair costs.
Oil burning may persist after replacing the oil seal, which is quite normal. Having driven for years, I've seen many people become careless after changing the oil seal, only to find the issue remains. The key is that oil burning has multiple root causes: damaged piston rings or a clogged crankcase ventilation system could be contributing factors. It's advisable to monitor the oil consumption rate for a week after replacing the oil seal. If it exceeds 500 milliliters per 1,000 kilometers, promptly return for an internal engine inspection. Additionally, avoid high-speed or long-distance racing and maintain good driving habits. Regular maintenance with high-quality oil additives can help reduce wear and prolong the car's stable period. In short, early intervention prevents chain failures and makes the car more durable.
