What does a rattling engine mean?
You usually hear this noise when accelerating the vehicle. Most people call this a pinging or rattling sound. This noise is caused by an air/fuel mixture in the engine cylinder being ignited prematurely by the heat of compression as the piston is moving up on the compression stroke.
Can low oil cause rattling?
Reason, Low Engine Oil Level:
And, if the oil level gets too low, you can have a situation; where the oil pump sucks air into it; and the air gets pumped through the engine, along with whatever oil is remaining. As a result, this can cause a rattling or ticking noise from within the engine.
What could cause a knocking noise in the engine?
When exposed to a spark, the ignited fuel consumes the air, creating the explosion. However, an improper mixture will cause a weaker, louder explosion that can be heard as a “knocking” sound. A bad air/fuel mixture can also be caused by interrupted or bad timing.
Why is my car making a rattling noise under the hood?

What does a bad piston sound like?
A hollow, muffled, almost bell-like sound is usually piston slap. This condition is caused by a piston rocking back and forth within its cylinder. ... A continuous piston slap sound is usually caused by worn pistons, excessive piston-to-wall clearance, misaligned connecting rods, worn cylinder walls, or inadequate oil.
What does timing chain rattle sound like?
