Will thick carbon deposits cause the problem of burning engine oil?
The 14 Passat, 1.8T, has a driving range of 114,000 kilometers. The vehicle consumes 2000 liters of fuel per 1 km. Upon inspection, no significant problems were found, but there was a thick carbon deposit.
When the Passat burns oil, the key components should be carefully inspected first. This includes the condition of components such as cylinder pressure, cylinder walls, and exhaust valves. When replacing a wastegas valve, special attention needs to be paid to whether it is an original spare part and whether its model is suitable for the vehicle. When dealing with this problem, it is necessary to avoid rushing and blindly overhauling the engine. Because burning engine oil often leads to a series of problems, such as vehicle shaking, lack of power, and increased fuel consumption. These phenomena are indirect manifestations of burning engine oil, so the fundamental problem of burning engine oil should be addressed as a priority. If the fitting is found to be faulty after inspection, it may be caused by the piston ring stagnation. In this case, the use of PNF repair agent and six consecutive uses can effectively solve the piston ring stuck problem without the need for extensive repairs.
