Details of what each spark plug indicates about your car’s condition:

Top Row

- Normal spark plug: The insulator tip has a light tan or grayish color, with minimal deposits. This means the engine is running efficiently, with the correct air-fuel mixture and proper ignition timing.
- High fuel consumption: The plug appears black and sooty, indicating incomplete combustion from a rich air-fuel mixture (too much fuel, not enough air). Possible causes include a faulty oxygen sensor, clogged air filter, or malfunctioning fuel injector.
- Lean air-fuel mixture: The plug may look white or have eroded electrodes, with little to no deposits. A lean mixture (too much air, not enough fuel) can cause overheating and potential engine damage, often linked to vacuum leaks, clogged fuel injectors, or a faulty mass airflow sensor.
- Excessive amount of additives: The plug has an unusual orange or rust-like discoloration on the insulator and metal components. This is typically from overusing fuel additives or oil treatments that leave behind deposits.

Bottom Row

- Poor condition of valve stem seals: The plug shows oil deposits (wet, oily coating) on the electrodes and insulator. Worn valve stem seals allow engine oil to leak into the combustion chamber, leading to incomplete burning and fouling.
- Valve damage or broken piston ring lands: The plug may have visible damage (e.g., cracked insulator, melted electrodes) or heavy deposits mixed with metal particles. This points to internal engine issues where combustion gases or debris are escaping due to damaged valves or piston components.
- Prolonged engine operation with detonation, use of low-octane fuel, or very early ignition timing: The plug has signs of overheating, such as a blistered or melted insulator tip, or eroded electrodes. Detonation (knocking) from low-octane fuel or incorrect timing causes extreme heat that damages the plug and can harm engine parts over time.
- Oil burning due to worn or stuck piston oil rings: Similar to valve seal issues, the plug has thick oil deposits, but this is caused by piston rings that can’t properly seal the cylinder walls. This allows oil to enter the combustion chamber, leading to smoke from the exhaust and reduced engine performance.

Master cylinder components:🚘🚗

- Brake Fluid Reservoir: This holds the brake fluid, which is essential for the hydraulic brake system to function. It is usually made of transparent plastic to allow easy monitoring of the fluid level.

- Master Cylinder: The master cylinder converts mechanical force from the brake pedal into hydraulic pressure. When the brake pedal is pressed, it pushes a piston inside the master cylinder, which pressurizes the brake fluid.

- Brake Hose: These flexible hoses transport brake fluid from the master cylinder to the brake calipers at each wheel. They need to be durable and flexible to withstand high pressure and constant movement.

- Brake Pedal: The brake pedal is what the driver presses to activate the braking system. The force applied to the pedal is mechanically amplified and then transmitted to the master cylinder.

- Brake Pad: Brake pads are friction material pressed against the rotor to slow or stop the wheel. They are a wear item and need to be replaced periodically.

- Rotor: Also known as a brake disc, the rotor is a metal disc connected to the wheel hub. The brake caliper squeezes the brake pads against the rotor to create friction and slow the wheel.
