What to Do About Oil Leakage in Haval H6 Turbo?
2 Answers
Haval h6 turbo oil leakage solution is: 1. Check whether the crankcase ventilation device is blocked or working abnormally; 2. Replace the supercharger. The Haval H6 is a compact SUV under Great Wall Motors. Taking the Haval H6 2021 3rd Generation Automatic Two-Wheel Drive MAX as an example, its body dimensions are: length 4653mm, width 1886mm, height 1730mm. The Haval H6 2021 3rd Generation Automatic Two-Wheel Drive MAX is equipped with a 2.0t turbocharged engine, with a maximum power of 155 kilowatts and a maximum power speed of 6000 to 6300 revolutions per minute, matched with a 7-speed dual-clutch transmission.
Last time at the repair shop, I saw an H6 with turbo oil leakage too. The mechanic said this issue absolutely can't be delayed. It's most likely either the intercooler connector seal aging or loose oil inlet pipe screws. If the oil stains are mainly near the turbo intake pipe, replacing a high-temperature resistant gasket can solve it. But if oil leakage is found at the turbo body's oil port, the bearing wear needs to be checked. Simple carbon cleaning treatments won't work at all - the oil passages must be disassembled for inspection. I suggest first wiping clean the leaking area, starting the cold engine and revving it twice before immediately shutting it off, then using a flashlight to see where fresh oil stains emerge from. Repairing the turbo requires removing the exhaust manifold together - this isn't a job for roadside stalls. It's more reliable to go directly to a Haval 4A dealership to replace the original seal components.
