Why is my brain clicking?
Tinnitus, also called head noise, is a ringing, buzzing, whooshing, or clicking noise that only the sufferer can hear. Potential causes can vary widely, and commonly include hearing loss, high blood pressure, and chronic medical conditions.
What causes an engine to make a ticking noise?
Oil is what lubricates and cools the engine’s moving components. Obviously, a low level of oil in the engine will cause these components to generate too much heat.
Why does my car make a clicking noise when I idle?
The first noise you described sounds like valve lifter noise. You will hear this sound if the engine is low on oil. Check the oil level and add if necessary. The lifter noise is not heard at higher RPMs because the oil pressure is higher as the engine speed gets higher. If you have high mileage, you could benefit from the next higher viscosity oil.
What’s the difference between a ticking and a knocking noise?
While a ticking noise is higher pitched and closer in context to a rattling of sorts, engine knock sounds more like a repetitive hammering and is often much louder. Engine knocking is also generally far more serious than ticking. A loud “smacking”, or knocking noise often signifies a much more severe internal engine issue than a tick.
What should I do if I hear a ticking noise in my car?
If a ticking noise becomes evident, you should begin by checking your engine’s oil level. Low engine oil can starve a vehicle’s components of valuable lubrication, thereby leading to metal-on-metal chatter. If your engine’s oil level is found to be low, it should be topped off immediately, and the source of any leaks should be located.
Is it normal for an engine to make a ticking noise?
Engine ticking noises are fairly common, and they can be either really bad news or not very serious, depending on the cause. In some cases, they can even be completely normal. Let’s run through some possibilities, starting with the most urgent. This is the most severe — and potentially costly — cause of a ticking engine.

The lifter noise is not heard at higher RPMs because the oil pressure is higher as the engine speed gets higher. If you have high mileage, you could benefit from the next higher viscosity oil.
Why does the fuel injector make a ticking sound?
Fuel injectors are small electrical valves that make clicking and ticking sounds when quickly opening and closing at idle. Ticking of the injectors is normal and you can drive without any worry.
While a ticking noise is higher pitched and closer in context to a rattling of sorts, engine knock sounds more like a repetitive hammering and is often much louder. Engine knocking is also generally far more serious than ticking. A loud “smacking”, or knocking noise often signifies a much more severe internal engine issue than a tick.
