How to Solve the Turbo Oil Leak Issue in Haval H6?
2 Answers
Haval H6 turbo oil leakage may be caused by failures in components such as the crankcase ventilation device, air filter, or supercharger. In case of turbo oil leakage, it is necessary to conduct a step-by-step inspection to identify the cause of the leakage and then proceed with repairs. Replacement of the turbocharger may be required if necessary. Below is an introduction to the turbocharger: The turbocharger is essentially an air compressor that increases the intake air volume by compressing air. It utilizes the inertial impulse of exhaust gases from the engine to drive the turbine in the turbine chamber, which in turn drives the coaxial impeller. The impeller then pressurizes the air delivered through the air filter pipeline, forcing it into the cylinders.
I recently helped a friend deal with the same turbo oil leak issue on their car. This is quite common in Haval H6 models, especially those over five or six years old. The most frequent problem is the aging seal ring at the intake pipe joint—you can open the hood and see obvious oil stains near the turbo. If the leak isn't severe, spending around a hundred yuan to replace the seal ring should fix it. However, if there are cracks in the turbo housing or severe wear on the blade bearings, the entire turbo assembly will need replacement. Don't delay, as a turbo oil leak can cause blue smoke from the exhaust and, in severe cases, lead to oil burning. Also, remember to check if the turbo boost pressure is normal—last time, my friend's car had weak acceleration due to the oil leak. It's best to have a mechanic inspect it thoroughly at a repair shop.
