The timing system can cause oil burning. If the timing is not correct, it can cause abnormal wear of the connecting rod bearing, excessive clearance between the cylinder and the piston connecting rod, and the piston connecting rod will carry oil up through the piston ring during movement, resulting in oil burning.
If the formal chain is replaced normally. There will be no oil burning situation, it is necessary to check and replace the formal chain. Has there been any oil burning situation before? If not? It should be done during the replacement process. Some parts are not installed properly, and some sealing components.
Inadequate sealing may cause oil to enter the intake pipe. Or inside the combustion chamber. But most of the reason should be the vehicle. The valve oil seal is damaged due to prolonged use. Crankcase ventilation malfunction or. Damage and leakage of cylinder gasket or aging of piston ring caused by blockage of oil pipe.
Precautions
1. Carbon deposits in the grooves of the piston can cause the piston rings to stick together, resulting in the piston rings getting stuck and unable to seal completely. The "stuck" piston rings greatly reduce the oil scraping and sealing ability. In addition, oil sludge can also block the oil return hole, preventing oil from flowing back normally and increasing oil consumption.
2. Carbon buildup will exacerbate the wear between the piston and cylinder wall, causing excessive clearance and allowing oil to enter the combustion chamber.
3. The corrosion and aging of valve oil seals cause poor sealing. Valve oil seals can be said to be the most vulnerable parts in engines that are prone to aging. Basically, cars that have driven more than 100000 kilometers have this problem.
4. The aging of the front and rear crankshaft oil seals results in extensive and continuous contact between them and the oil. Impurities in the oil and continuous temperature changes inside the engine gradually weaken their sealing effect, leading to oil leakage or seepage.
5. The main reason for the damage to the oil seal between the turbocharger and the intake pipe is that the oil change cycle is too long or inferior oil is used, resulting in a lack of lubrication and heat dissipation on the floating turbine main shaft, which in turn damages the oil seal.
