- Insufficient oil pressure
- Reduced lubrication to engine components
- Knocking sounds
2. Worn Engine Bearings:
- Extended periods of low oil
- Wear and damage to bearings
- Knocking sounds
3. Piston Slap:
- Excessive clearance between piston and cylinder walls
- Loose or worn pistons and/or rings
- Knocking sounds
4. Damaged Connecting Rods:
- Bending or damage to connecting rods
- Rod bearing failure
- Knocking sounds
5. Timing Issues:
- Incorrect valve timing
- Damaged timing chain or belt
- Knocking sounds
6. Carbon Buildup:
- Accumulated deposits in the combustion chamber
- Increased pressure, causing detonation and knocking sounds
7. Faulty Engine Mounts:
- Loose or broken mounts
- Engine movement, resulting in knocking sounds
8. Fuel Concerns:
- Low-quality fuel with unsuitable octane levels
- Premature detonation leading to knocking sounds
9. Defective Knock Sensor:
- Malfunctioning sensor
- Incorrect information to the engine control unit (ECU)
- Inability to adjust engine timing to reduce knocking
