How to Deal with Volvo Burning Engine Oil?
3 Answers
Valve stem seals causing engine oil burning can be simply explained as aging and deformation of the valve stem seals leading to oil leakage, which allows oil to enter the combustion chamber. Replacing the crankcase ventilation system can address the issue of oil loss. A poorly sealed or incorrectly installed crankcase ventilation check valve allows oil to enter the combustion chamber along with the combustible mixture through the intake pipe.
I also drive a Volvo. When encountering oil burning, the first thing I do is check the dipstick to see how quickly the oil level is dropping. If it's not too severe, I try using some oil additives—some work quite well. But if the oil consumption is excessive, then it's necessary to identify the cause. Common issues include worn piston rings or aging valve stem seals. I've experienced this before; when it was mild, I added higher-viscosity oil to mitigate the problem. Don't delay addressing oil burning issues—prolonged neglect can lead to engine overheating, affecting vehicle reliability and safety. I recommend regular maintenance, changing the oil every 5,000 kilometers, and using high-quality full synthetic oil to reduce wear. If you notice the issue, it's best to have a professional workshop inspect it—they can use tools to measure cylinder pressure and internal conditions. Repairs might be costly, but it's a worthwhile investment for the long-term use of your car. Volvo engines are exquisitely designed and can last many years with proper maintenance.
Having driven for decades, I've dealt with numerous cases of oil burning. Volvo commonly faces this issue with older engine models, especially certain turbocharged variants. The first step is to closely monitor oil consumption—keep track every thousand kilometers. For minor oil burning, switching to a slightly higher viscosity oil can effectively alleviate the problem. In severe cases, the engine needs to be disassembled to inspect piston rings or seals, as wear on these components can cause oil leaks. Finding an experienced repair shop is crucial; DIY attempts carry high risks and may damage other parts. After repairs, remember to change the oil regularly, not exceeding 5,000-kilometer intervals. Safety cannot be overlooked—prolonged oil burning may pose fire hazards. Post-repair, adjust your driving habits; avoid aggressive throttle use to protect engine longevity.
