Why Does the Valve Cover Gasket Keep Leaking Oil After Replacement?

The reasons for continued oil leakage after replacing the valve cover gasket include the following: 1. The crankcase forced ventilation valve is blocked, causing increased crankcase pressure, which then releases through the valve cover gasket or other weak points, resulting in oil leakage. 2. The valve cover gasket has aged, leading to poor sealing. 3. If the crankcase ventilation valve is clogged, or if the piston rings and cylinder wall gaps are too large, causing excessive blow-by gas, the high crankcase pressure will force gas to escape through weak sealing points, such as the valve cover gasket or front/rear crankshaft oil seals, resulting in engine oil leakage.

Why does the indicator light not change after a new battery is fully charged?

New battery indicator light not changing after full charge may be caused by battery water shortage. Below is an introduction to automotive battery knowledge: 1. Introduction: Automotive battery, also called storage battery, is a type of battery that works by converting chemical energy into electrical energy. Typically, what people refer to as batteries are lead-acid batteries. That is, a battery mainly made of lead and its oxides, with sulfuric acid solution as the electrolyte. 2. Ordinary battery: The plates of an ordinary battery are composed of lead and lead oxides, with an aqueous solution of sulfuric acid as the electrolyte. Its main advantages are stable voltage and low cost; the disadvantages are low specific energy (i.e., the electrical energy stored per kilogram of battery), short service life, and frequent daily maintenance.

What to Do When the Car Doesn't Respond to the Key Fob and Won't Start?

If the car doesn't respond to the key fob and won't start, you can use the mechanical key on the remote fob to start the car. This issue may occur due to a dead battery in the key fob, signal interference near airports or radio transmission towers, or if the car is out of fuel or has a dead battery. Additionally, the car may not respond if the anti-theft system is activated and cannot be unlocked. The basic principle of a car remote key: the key fob emits a weak radio wave, which is received by the car's antenna. The electronic control unit (ECU) then identifies the signal code, and the system's actuator (motor or electromagnetic coil) performs the action of starting, stopping, or locking the car.

What causes the smell of gasoline inside the car?

The reasons for smelling gasoline inside the car are as follows: 1. The fuel tank cap is not tightly sealed, or the carbon canister pipes are aged and cracked. In this case, focus on checking the sealing ring of the fuel tank. If you can fix it yourself, perform a simple repair; if not, replace the entire component. 2. Overfilling the fuel tank. If the tank is overfilled, gasoline may flow into the carbon canister through the pipes. The carbon canister, originally designed to collect gasoline vapors, will release excess gasoline vapors through the vent when invaded by liquid gasoline. When the air conditioning is in external circulation mode, the gasoline smell can enter the car. 3. Gasoline leakage. If this occurs, immediately send the car to a 4S shop for inspection. Gasoline leakage may be due to issues with the fuel pump's outlet or return pipes.
