How to Solve the Oil Burning Issue in Wey VV7?
2 Answers
Replace with higher viscosity engine oil, which can help alleviate the issue, you may consider trying this. Carbon deposits in the combustion chamber can cause the piston rings to stick, leading to poor sealing. In such cases, it is necessary to remove the carbon deposits and replace the piston rings.
My WEY VV7 also had oil burning issues before, and it was quite a hassle. Don't rush to dismantle the engine—first check if the valve stem seals are aged. If these leak, oil can sneak into the combustion chamber. A damaged turbocharger seal can also cause oil burning. Shine a flashlight on the intercooler pipe; if you spot oil stains, this might be the issue. Piston ring carbon buildup and sticking are the most troublesome—you'll need to measure cylinder pressure. If there's over a 10% difference, consider opening the engine to replace the rings. Also, don't use just any oil; stick to the manual's 0W-40 requirement. Oil with too low viscosity can evaporate under high heat. If the dipstick drops below the lower limit within 2,000 km, head to the dealership for a computer check on crankcase pressure—don't wait until cylinder scoring costs you tens of thousands in repairs. And avoid flooring the accelerator; driving gently is better for the car.
