1. If the oil pan is found to be leaking after the oil is replaced, the problem is analyzed as follows: the replaced oil does not meet the standard model of the original vehicle, causing the oil viscosity to be too thin and causing the fault;
3. The oil pan drain screw is loose or damaged, and the drain screw gasket plays a certain sealing role. This gasket is better to be replaced regularly according to the maintenance cycle. Tighten or replace the drain screw;
4. The oil pan gasket leaks locally, indicating that the gasket is aging or has quality problems. It is necessary to disassemble the oil pan, replace the oil pan gasket, or glue the local oil leakage fault point.
Oil leakage is not a fault, and oil leakage should be taken seriously. As long as the oil is not reduced, it will not be judged as oil leakage, but only oil leakage. Oil leakage has basically no effect on the car. After about 10,000 kilometers of normal use of the oil, the oil will be at a normal scale.
The oil pump is driven by the Petrol Car engine. The oil pump does not work if the Petrol Car engine is not started. When a Hongqi Car engine is cold started, the oil film left after the last parking is used to reduce the friction between the parts. If the vehicle has been parked for a long time, the oil will flow down, and the oil film may be very small or non-existent. The main friction is between the piston ring and the cylinder barrel. The crankshaft is "soaked" in the oil, and the camshaft above moves relatively "slowly" and the oil pump pumps the oil to it as soon as the Hongqi Car engine is started. Therefore, when it is cold, you should move the car every day and let the Hongqi Car engine fully warm up.
