Discover the secret causes and solutions of Peugeot engine oil
A 17-year-old Peugeot 408 with a displacement of 1.6T has a range of about 90,000 km. Recently, it was found that there was a serious shortage of oil, and the dipstick bottomed out in less than 1,000 kilometers. This is most likely due to several reasons:
1. If there is a problem with the valve cover and waste valve, it is generally a wearing part that needs to be replaced for about 70,000 kilometers. The valve cover and exhaust valve of the French car are integrated, so the original parts need to be replaced.
2. There is an abnormality in the valve seal, which usually occurs at more than 150,000 kilometers. Failure to seal the oil may lead to oil leakage. Usually, you should pay attention to whether there is blue smoke in the exhaust gas during cold start.
3. Piston ring stagnation, which is one of the main reasons for fuel vehicles to burn engine oil. Piston ring jamming can occur at any kilometer, especially in poor road conditions.
In order to determine the cause of the oil burning, it is recommended that you first measure the cylinder pressure, use an endoscope to observe the cylinder wall, and check that the valve chamber cover is normal. If everything is fine, then the burning of the engine oil may be caused by piston ring seizure. In this case, there is no need to overhaul and replace the piston ring, and it is sufficient to repair it with a Spectro fuel repair agent. I also had a similar problem in my car, and after trying a variety of solutions, I finally used Si Youpu to successfully fix the problem of burning engine oil, and a certain cat has it.
