Engine making aeroplane sound

[ishoppersmarketing]

the air leak

 

[winfong]

intake roar? turbo whirl sound?.....water pump?...

take a pvc washing machine pipe to locate where the whirl is coming from....
wiggle water pump spindle, see if loose (WHEN ENGINE IS OFF *VERY IMPORTANT*).....

TS already responded that car in neutral (i.e. not moving) and rev engine still have sound. How can it be wheel bearing?

Oh, sorry never read properly.... my mistake

I suppose quite a number of things can cause this 'aeroplane' sound

Battery alternator. Check whether your battery is charge up or not..

the sound quite long liao, almost 2 months, so i presume its not the alternator since it is still moving..

thank you all for kind advise. Will send to workshop to check all the belts first.

will update results for all to gain more insight if it happens to u(touch wood!)

Aeroplane sound is often cause by bad wiring from ur headunit or sound system. The sound is from ur speakers. Especially when u r in neutral n u rev ur engine n the sound become louder. Quite confirm is ur sound wiring.

Could I trouble you to explain in a bit more detail, how a sound that increases proportionally to the engine revs can be related to the sound system or speakers?

Thanks.

I think more likely a bearing than a belt, if I interpret the term 'aeroplane sound' correctly Belt problems usually cause a high-pitched screeching sound, sometimes pulsating.

TS,

do you drive the Mit Colt?

 

[Alphas]

It is just a grounding problem

 

[zulu35]

Alternator whine. Like alphas said, it's a grounding problem. Usually with your audio system.

ok, the problems lies with no oil/lubricant in the air con compressor.

mentioned that i send for regular servicing but no one ever told me about the oil.. the compressor totally no oil..

the mechanic says it is not the usual thing that servicing packages check.

so here it is... do take note of your air con compressor oil.

Yes, normal servicing they don't check a/c.

Actually alot of things didn't check unless told to.

My mechanic same, always told him to check this and that but finally said all working fine.
