Does the Citroen 1.6T Engine Burn Oil?

[LaEliza]

Some Citroen models equipped with the 1.6-liter turbocharged engine experience oil burning issues. Here are details about the Citroen 1.6-liter turbocharged engine: Causes of oil burning: The oil burning in Citroen's 1.6-liter turbocharged engine is primarily caused by aging valve components. Specifically, it occurs due to deteriorated valve stem seals. To resolve this issue, replacement with new valve stem seals is required. Valve stem seals are rubber components that lose elasticity and harden when exposed to prolonged high-temperature and high-pressure operating conditions, resulting in compromised sealing performance. If the valve stem seals' sealing capability deteriorates, engine oil can flow along with the air into the combustion chamber where it gets burned, leading to severe oil consumption. Other causes: Some engines experience oil burning due to excessive clearance between piston rings and cylinder walls. In such cases, oil on the cylinder walls cannot be properly scraped off, causing it to burn during engine combustion.
