Does Coolant Entering Engine Oil Require an Overhaul?

If the engine block has developed cracks causing coolant to enter the engine oil, an overhaul is required to replace the engine block. If the issue is due to cracks in the cylinder head gasket allowing coolant to mix with the oil, it is also necessary to remove the cylinder head and replace the gasket. Both removing the cylinder head and replacing the engine block constitute major overhauls, hence coolant entering the engine oil necessitates an overhaul. Here are the relevant details: 1. Coolant entering engine oil is highly dangerous, as it can cause the oil to emulsify. Once emulsified, the oil can no longer provide adequate lubrication to the engine, significantly increasing the risk of engine cylinder scoring. Therefore, immediate repair is essential when this occurs. Additionally, cracks in the engine block or cylinder head gasket can allow high-pressure gases from the engine to enter the cooling system, leading to excessive pressure that disrupts normal cooling system operation. 2. The cylinder head gasket is a sealing component between the engine block and cylinder head. It is normal for the gasket to develop cracks over time due to prolonged exposure to high temperatures and pressure. Regular maintenance and timely replacement of coolant are recommended. Avoid using water as a substitute for coolant, as this can lead to rust in the engine block or clogged coolant passages, which may cause the engine to overheat. Overheating can result in cylinder scoring.

What kind of device is OBU?

OBU stands for On-Board Unit. It is a microwave device that uses DSRC (Dedicated Short-Range Communication) technology to communicate with RSU. In the ETC system, the OBU is placed in the vehicle, while the Roadside Unit (RSU) is installed along the roadside, and they communicate with each other via microwave. Here is supplementary information about ETC: The full definition of highway ETC is "Electronic Toll Collection System," with the English acronym "ETC." The ETC system is a large-scale system consisting of two parts: one is the vehicle sensing and signal transmission system installed in dedicated lanes at toll stations, and the other is the electronic tag (OBU) installed in the vehicle, which stores vehicle information.

Where is the Porsche one-button start key located?

Porsche one-button start key is located on the left side of the dashboard near the steering wheel, and it operates by rotation. The specific usage method is as follows: 1. Open the driver's door of the Porsche and place the smart key inside the vehicle. 2. Depress the brake pedal and turn the one-button start key. At this point, the dashboard will light up and the vehicle will start. The functions of the one-button start are as follows: 1. Intelligent vehicle and owner identification When the vehicle enters anti-theft mode, the smart one-button start system only recognizes the owner carrying the spare key. If the door is forced open without smart key identification and unlocking, the system will automatically consider it an illegal operation and trigger vibration, sound, and light alarms. 2. Intelligent sensing for door opening and closing When you approach the vehicle, the RFID intelligent detection system will automatically unlock the door within a range of 1.0-2.0 meters. The sensing distance is stable and non-directional, accompanied by flashing turn signals, a short horn sound, and sound and light prompts. 3. Fuel and power cut-off anti-theft function When the vehicle enters anti-theft mode, it will automatically cut off the electrical and fuel systems. At this time, the smart key is the only legal unlocking device. Only after successful identification between the smart key and the one-button start system will the vehicle's fuel and electrical systems resume normal operation. 4. Automatic window closing and remote vehicle start This function is optional on the one-button start system and is generally only available on vehicles equipped with top-tier intelligent vehicle start systems.

How long can you stay at a highway service area before leaving?

Here are the regulations regarding rest time at highway service areas: 1. There is no time limit for resting at highway service areas, but expressways impose overtime fees. The overtime fee is a nationwide highway network measure to prevent illegal activities such as toll evasion by swapping cards, targeting vehicles that exceed the allowed travel time. 2. Most expressways across the country have implemented procedures for handling vehicles that exceed the allowed travel time. However, the time spent resting at service areas or delays due to traffic accidents can be deducted. 3. According to the Road Traffic Safety Law, the minimum speed limit on expressways is generally 60 kilometers per hour. This standard already provides drivers with ample time, accounting for necessary rest and refueling periods. If a driver requires more time for rest or experiences delays due to refueling or vehicle repairs, as long as they can provide corresponding receipts or proof verified by the toll station, it will not be counted as overtime.

Should the Vehicle Anti-Skid System Be Kept On Normally?

Vehicle Anti-Skid System should be kept on normally. For most vehicles, this system is enabled by default. In certain special driving conditions, if it needs to be turned off, it can be deactivated via the vehicle's anti-skid switch. Once turned off, the anti-skid system will no longer provide protection. Here is some relevant information about the Vehicle Anti-Skid System: The Vehicle Anti-Skid System generally includes the functions of the Anti-lock Braking System (ABS) and Traction Control System (TCS). On this basis, it adds a yaw rate sensor, lateral acceleration sensor, and steering wheel angle sensor when the vehicle is steering. The system controls the driving and braking forces of the front, rear, left, and right wheels through the ECU to ensure the lateral stability of the vehicle during driving.
