How to Solve the Oil Burning Issue in Haval H6?

[MacConnor]

Haval H6 oil burning can be resolved by replacing valve stem seals, cylinder liners, or repairing the engine. The oil burning issue can be diagnosed through the following methods: 1. Cold-start oil burning: When starting the car for the first time each day, thick blue smoke may be emitted from the exhaust pipe. The blue smoke usually disappears after a while and does not recur for the rest of the day. 2. Oil burning during acceleration: When the driver accelerates sharply while driving or revs the engine while stationary, large amounts of blue smoke are emitted from the exhaust pipe. 3. For vehicles suspected of oil burning, fill the engine with oil and have the owner drive 1,000 kilometers before returning to the service station to weigh the oil and filter. Then refill the oil and repeat the 1,000-kilometer drive. Repeat this process three times to obtain an average value. After the break-in period, normal oil consumption is generally around 0.3 liters per 1,000 kilometers. If the consumption exceeds this level, it indicates an oil burning issue.

Seeing the issue of oil burning in the Haval H6 is quite common. As someone who often helps friends with car repairs, I would start with simple checks: inspect whether the engine oil is leaking or the wrong type was added. Sometimes, damaged piston rings or valve stem seals are the main culprits, causing oil to enter the combustion chamber and burn. If you notice blue smoke from the exhaust pipe or the oil level on the dipstick dropping rapidly, it's best to visit a professional shop for a cylinder compression test with specialized equipment. If confirmed, it might be necessary to partially disassemble the engine to replace these components. For daily prevention, regularly change to high-quality engine oil, such as the specifications recommended by the manufacturer, to avoid engine overheating and wear. Don’t delay too long—prolonged oil burning can reduce engine power and waste money. After repairs, proper maintenance can extend the car's lifespan by several years, and the cost is usually just a few hundred to a thousand yuan.

I've been driving a Haval H6 for several years and encountered the oil burning issue last year. At first, the oil level kept dropping rapidly, which scared me into constantly checking the dipstick. Later, I found out it was due to worn piston rings, and the problem was fixed after a repair at the shop. The solution is actually straightforward: first, try changing the oil yourself to see if it's caused by low-quality oil; if that doesn't work, have a technician diagnose whether there's a leak in the valve seals or turbo. For prevention, I make it a habit to change the oil and inspect the seals every 5,000 kilometers to avoid worsening carbon buildup. If left unrepaired, this issue could lead to engine failure. Addressing it early saves money and ensures safety. Sharing this with fellow H6 drivers for reference.

Working in the auto repair industry for a long time, the issue of oil burning in Haval H6 is quite common, mostly caused by aging piston rings or oil seal leaks allowing oil to enter the combustion chamber and burn. The solution is a comprehensive inspection: use professional tools to measure cylinder pressure and smoke emissions, and after confirmation, replace the damaged parts; turbo issues must also be checked, as oil leaks can lead to chain failures. After repair, use synthetic oil for maintenance, and regularly check for engine carbon buildup and seals during routine maintenance. Ignoring oil burning can halve the engine's lifespan, so it's advised that owners not skimp on small expenses—getting a professional diagnosis done right the first time is the most cost-effective.
