How to Solve the Severe Oil Burning Issue in the 2017 VV7?
2 Answers
Solutions for severe oil burning in the 2017 VV7: If the piston rings are failing and causing oil burning, they need to be replaced; If the valve stem seals are aged or damaged, leading to oil burning, they should be replaced promptly; If wear has reduced cylinder sealing performance, using higher viscosity oil can help alleviate the issue. Engine oil, also known as engine lubricant, serves multiple functions including lubrication, cooling, sealing, rust prevention, and shock absorption for the engine. Engine oil consists of base oil and additives. The base oil is the primary component, determining the fundamental properties of the lubricant, while additives compensate for and enhance the base oil's performance, providing additional beneficial properties. Poor sealing performance of valve seals, damage to the crankcase forced ventilation valve, or clogged crankcase ventilation ports causing excessive pressure can all lead to oil entering the combustion chamber along with crankcase gases.
I've driven a 2017 VV7, and the severe oil burning issue was indeed a headache, possibly due to worn piston rings or valve guide leakage. I suggest checking it yourself first: use the dipstick to measure oil consumption. If it drops half a liter after just a few hundred kilometers, that's a red flag. Try switching to a high-quality full synthetic oil—I added some cleaning additives to reduce carbon buildup. If that doesn't work, check the engine cylinder pressure. Low pressure indicates faulty piston rings, in which case you'll need to visit a professional shop to replace the rings or seals. Regular maintenance is crucial: change the oil every 5,000 kilometers and avoid sudden high-speed acceleration to prevent excessive wear. Oil burning isn't just costly; it can also lead to breakdowns. Based on my personal experience, addressing it promptly is the way to go—delaying could mean a pricier engine overhaul later.
