Why is there a knocking sound coming from my engine?

Many things can cause engine knocking or banging. Common causes are: carbon buildup in the combustion chambers or on cylinder walls, lifters or connecting rods, combustion timing out of sync, overheated engine, back pressure from the exhaust, vacuum leaks, fuel octane or quality, spark plugs, or knock sensors failing.

What does it mean when your engine is making a knocking noise?

The knocking sound often occurs when the air-fuel mixture is incorrect, which causes the fuel to burn in uneven pockets rather than uniform bursts. Left untreated, it can cause damage to the piston and cylinder wall. A knocking sound can also be caused by a lack of lubrication in the upper cylinder head area.

Why does my engine ping when I accelerate?

An engine will begin to ping at a relatively rapid pace when the fuel grade gets too low in its octane rating. A pinging noise in the engine can also indicate the need to repair the part of the car that tells the coil when to fire the cylinder. You might have carbon build-up in the combustion chamber.

How do you troubleshoot an engine noise?

Sounds like: Clicking noise during acceleration. Try troubleshooting each cylinder by removing the spark plugs and adding a spoonful of engine oil to each cylinder. Now crank the engine quite a few revolutions to allow the oil to go down past the rings. Install the spark plugs and start the motor.
