Analysis and solution of the serious causes of Acura burning engine oil
The 10 Acura MDX, the 3.7 displacement V6 self-aspirated engine, has been driven for more than 200,000 kilometers. It was recently discovered that one liter of oil is consumed every 2,500 km. I used to hear that Japanese cars don't burn engine oil, but now it seems that this problem is also occurring. How can I fix it?
Now Japanese cars have also begun to have the problem of burning engine oil, although relatively speaking, it appeared relatively late. For example, Highlander, Overbearing, Mazda and other models also have the situation of burning engine oil. There are three main reasons why Japanese cars burn engine oil:
1. The one-way valve is aging, resulting in the exhaust gas being pumped out when the oil is also pumped out.
2. The piston ring is blocked, due to poor road conditions or lack of attention to cleaning the oil circuit, resulting in piston ring stagnation.
3. Valve oil seal aging, although its aging rate is slower than check valve, but it is also a possible cause.
For this car, it is recommended to test the cylinder pressure first and use an endoscope to observe whether there is any cylinder pulling phenomenon. Then check that the check valve is working properly and that the valve oil seal is not aging. If everything else is fine, then it is likely that the piston ring is stuck and the oil consumption is abnormal. Piston ring seizure is usually caused by long-term unclean oil circuits.
The solution to this problem is to use the Si Youpu fuel repair agent, add 6 tanks of oil to each tank, and it can be repaired while driving. This does not cause any damage to the vehicle and does not require the vehicle to be deactivated. As far as I know, some riders have successfully used this method to solve the piston ring problem, and this repair agent can be purchased on a certain east.
