What are the repair methods for severe oil burning in the Magotan?
2 Answers
Oil burning can be repaired by replacing components such as piston rings and valve stem seals. The reasons for oil burning include the following: 1. Carbon deposits accumulate in the piston grooves, causing the piston rings to stick together and become stuck, preventing them from sealing completely. The "stuck" piston rings significantly reduce their oil-scraping and sealing capabilities. Sludge can also clog the oil return holes, preventing oil from returning normally, leading to increased oil consumption. 2. Carbon deposits can accelerate wear between the piston and cylinder walls, creating excessive clearance and allowing oil to enter the combustion chamber. 3. Corrosion and aging of the valve stem seals can result in poor sealing. 4. Aging of the front and rear crankshaft oil seals. These seals are in extensive and continuous contact with oil, and the impurities in the oil along with the constant temperature changes inside the engine gradually weaken their sealing effectiveness, leading to oil seepage or leaks.
I've been repairing cars for many years. The severe oil burning issue in the Magotan is typically a common problem with the EA888 engine, mainly caused by piston ring wear or aging valve stem seals leading to oil seepage into the combustion chamber. Professional methods are required for repair - first conduct cylinder compression tests and leak-down tests to confirm the root cause. If it's a piston ring issue, disassembling the engine to replace the rings is the most thorough solution, sometimes requiring upgraded valve stem seals as well. The entire process may take about two days at a proper repair shop, costing anywhere from several thousand to over ten thousand yuan depending on severity. Routine maintenance is also crucial - use high-quality full synthetic oil of the correct specification, change filters frequently, and avoid prolonged high-load driving. Don't believe additives can provide a permanent fix; they only offer temporary relief. Safety first - address the issue early to prevent emission violations or further damage.
