What to Do When Honda Odyssey Engine Burns Oil?
2 Answers
If you notice abnormal oil consumption, you should take your vehicle to a repair shop for inspection and replace the oil filter. Additionally, it is recommended to use high-quality engine oil and change it regularly to maximize its lubricating effect on the engine. Extended Information: The reasons for burning oil can generally be attributed to the following points: 1. Due to the difference in fuel quality standards between China and international standards, a large amount of carbon deposits can easily form in the combustion chamber during engine operation, which is the root cause of various engine problems. 2. A clogged air filter can obstruct the intake airflow, reducing intake pressure and creating a vacuum, which draws oil into the combustion chamber, leading to oil burning. 3. A blocked or damaged exhaust gas recirculation (EGR) valve can cause oil and gas mixtures to solidify and enter the intake manifold through the exhaust gas recirculation pipe, resulting in oil consumption. 4. Corroded or aged valve stem seals can lead to poor sealing. 5. A clogged oil filter can increase oil consumption.
My friend's Odyssey recently had a similar issue. Actually, there are usually three scenarios for oil burning: Worn or stuck piston rings are the main cause, especially common in vehicles over ten years old; another is hardened valve stem seals allowing oil to seep into the combustion chamber along the valve stems; and a faulty turbocharger seal can also cause oil leakage. As a short-term emergency measure, always keep a bottle of the same grade oil in the trunk and add a liter immediately when the oil light comes on. In the long run, the engine needs to be disassembled for inspection, and replacing upgraded piston rings and valve stem seals is the most fundamental solution. By the way, don't overlook the PCV valve – if it fails, it can cause an imbalance in crankcase pressure, sucking oil into the intake pipe.
