Car Mechanic Simulator 2021: Knocking Noises from Engine Bay
If you’re hearing knocking noises from your engine bay, it’s important to take your car to a mechanic as soon as possible. Knocking noises can be caused by a variety of problems, including:
- Worn or loose engine components
- Insufficient oil lubrication
- Detonation or pre-ignition
The sooner you take your car to a mechanic, the better. Ignoring knocking noises can lead to serious engine damage.
Worn or Loose Engine Components
Worn or loose engine components can cause knocking noises by impacting against each other. Common culprits include:
- Piston slap
- Connecting rod bearing knock
- Valve train wear
These problems can be caused by a variety of factors, including high mileage, poor maintenance, and over-revving the engine.
Insufficient Oil Lubrication
Insufficient oil lubrication can cause knocking noises by allowing metal components to rub against each other. This can occur due to:
- Low oil levels
- Dirty or contaminated oil
- Oil pump failure
It’s important to check your oil level and condition regularly and change your oil and oil filter according to your vehicle’s maintenance schedule.
Detonation or Pre-Ignition
Detonation or pre-ignition occurs when the air/fuel mixture in the engine ignites too early. This can cause a knocking noise and can also damage the engine. Detonation or pre-ignition can be caused by:
- Low-octane fuel
- Overheated engine
- Carbon buildup in the engine
If you’re hearing knocking noises from your engine bay, it’s important to take your car to a mechanic as soon as possible to have the problem diagnosed and repaired. Ignoring knocking noises can lead to serious engine damage.
