What Causes Oil Spray from the Exhaust Pipe?

It is normal for a diesel engine's exhaust pipe to have slight oil spray or a small amount of oil at the outlet. However, severe oil dripping from the exhaust pipe is abnormal. The exhaust pipe is usually connected to the crankcase or valve cover. Possible reasons include: 1. The crankcase ventilation valve is aging, or there is a malfunction in the piston, cylinder liner, piston pin, or piston rings, leading to a loss of sealing effect and causing oil spray. 2. Severe wear between the valve stem and valve guide creates excessive clearance, resulting in oil leakage downward. 3. The design itself has defects, leading to oil spray from the exhaust pipe.

What is the suitable tire pressure for winter?

Each vehicle has different tire pressure requirements. In summer, the recommended tire pressure generally ranges between 2.2 to 2.4 kilopascals. Additionally, factors such as season, load, and whether the tires are cold or hot can also have an impact. 1. Excessive tire pressure reduces the contact area between the tire and the ground, increasing the pressure per unit area and accelerating wear. This can easily lead to loss of braking control, and encountering road protrusions or depressions may cause tire blowouts, damaging the vehicle's suspension system and causing discomfort to passengers. 2. Tire pressure should not be too low either. Insufficient tire pressure increases the contact area between the tire and the ground, causing abnormal temperature rise inside the tire during driving, increasing fuel consumption, and shortening the tire's lifespan.

Why is the fuel consumption of the new Roewe i5 so high?

The high fuel consumption of the new Roewe i5 is due to the break-in period, poor driving habits, and some objective factors. The specific reasons are as follows: 1. Break-in period: New cars are in the break-in period, where various components need to adjust and coordinate with each other. After this period, fuel consumption will decrease to some extent. 2. Poor driving habits: Some drivers prefer aggressive driving, such as revving the engine and sudden braking, which can increase fuel consumption even for fuel-efficient new cars and may also damage the vehicle, making it not worth the cost. 3. Objective factors: For example, prolonged idling and braking in traffic jams can significantly increase fuel consumption due to frequent stops and starts.

Is Replacing a Cylinder Head Gasket Considered an Engine Overhaul?

Replacing a cylinder head gasket is not considered an engine overhaul, but rather a medium repair. Relevant details are as follows: 1. Replacing a cylinder head gasket is not considered an engine overhaul, but rather a medium repair, and it has minimal impact on the engine. 2. After replacing the gasket, the engine should be started and run for a period of time before undergoing a secondary tightening to achieve the specified torque, ensuring proper subsequent use. Once tightened, it generally does not cause additional effects on the engine. Moreover, although replacing a cylinder head gasket is no longer classified as a major engine overhaul nowadays, it still involves technical difficulty and requires a certain level of skill from the mechanic, as well as a relatively long time to complete.

What does the P0140 fault code mean?

P0140 fault code indicates that the oxygen sensor circuit is inactive, specifically the second oxygen sensor in Bank 1. Possible causes of the fault include: 1. Exhaust manifold or exhaust pipe leakage. 2. Fault in the oxygen sensor itself, its circuit, or connector. 3. Fault in the electronic control module (PCM or ECM), etc. Here are some additional considerations: After troubleshooting, the fault code must be cleared promptly. Clearing the fault code should be performed by a professional. Do not attempt to clear the fault code by disconnecting the negative terminal of the battery, as this may cause the vehicle's computer to lose its learned memory, leading to certain functions becoming unavailable, reduced vehicle performance, and potential long-term repair difficulties. Additionally, the fault code may reappear after driving for some time.
