Can Replacing the Exhaust Valve Solve the Oil Burning Issue in Volkswagen Tiguan?
2 Answers
If the Volkswagen Tiguan experiences severe engine oil burning, replacing the exhaust valve can resolve the issue. Below is relevant information about the oil burning issue in Volkswagen Tiguan: Reasons for oil burning in Volkswagen Tiguan: If the Volkswagen Tiguan exhibits oil burning, there can be multiple causes. The most common ones include a damaged exhaust valve, faulty intake valve, carbon buildup in the combustion chamber, and corrosion or aging of the valve seals. When oil burning starts in Volkswagen Tiguan: Under normal driving conditions, the Volkswagen Tiguan typically starts burning engine oil around 80,000 kilometers. By 130,000 kilometers, if the engine oil cannot be burned, the engine should be repaired.
My opinion is that the Volkswagen Tiguan burns oil, and replacing the exhaust gas valve can sometimes solve the issue, but it's not a universal fix. From a technical perspective, a faulty exhaust gas valve allows oil vapor from the crankcase to leak into the intake tract, where it is directly burned, leading to rapid oil consumption. However, oil burning can also be caused by worn piston rings leaking oil or aging valve stem seals. Simply replacing the valve is only effective for valve-related issues; if the cause is unclear, it's advisable to first conduct a professional diagnosis, using a vacuum test or computer scan to confirm the problem. Otherwise, merely replacing the valve might be a waste of money, and prolonged oil burning can damage the catalytic converter, affecting the car's performance. Regularly check the oil dipstick, and if the level drops quickly, investigate immediately—don’t wait for the engine warning light. In terms of maintenance, changing the oil on time with high-quality oil can also reduce such issues. In short, targeted solutions are key.
