Knocking Noise From the Engine: What It Means
A knocking or tapping from the engine should never be ignored. A Cranbourne West specialist explains the common causes.
What it usually means
Engine knocking can range from minor to serious: low oil level or pressure, worn hydraulic lifters/tappets (a lighter tick), pre-ignition/“pinging” under load, or in the worst case worn bearings (a deeper knock). The sound and when it happens are big clues.
A deep knock that gets worse with revs is the most concerning and needs prompt diagnosis.
What you should do
Check your oil level first — low oil is a common, fixable cause. If the knock persists, stop driving hard and book a diagnosis before it becomes engine damage.
The cheaper the cause, the more important it is to catch it early.
How we find & fix it
Because the same symptom can have several causes, we use dealer-level diagnostics and a methodical check to pinpoint the real cause — rather than throwing parts at it.
