Celica Forums General Discussion General Whistle From My Engine

Can some1 please tell me why wvery morning when i turn on my car my engine makes a loud whistling sound like my headers are cracked or sumtin

Is it b/c my car is cold or is something wrong with my car

i noticed the same problem lately. and believe it or not i was about to ask the same question today but you beat me to it. i hope somebody knows what the problem is and let us know. i 'm really worried.

That same problem happen to my car a few months ago, every time I started the car early in the morning when the car is cold, i heard a weird sound. I when to the dealer and they change the belt, after that, the sound is gone.

My car makes a noise early in the morning also...but its just the belt tensioner .

The belt tensioner is more of a squeal.

A whistle might be more serious. Could be your exhaust flange between your manifold & pipe. Not a big deal.

Could be if you have a stock airbox, the fastners have come undone & its sucking air through the sides.

Open the hood & rev the engine & listen & figure out where it is coming from.

^^^^^ as stated before, their are many threads on this. Mine did the same and simple look-see helped. Mine was the tensioner, tightened and lubed, all good.

If it was a whistle like air in a crack, check your engine.

no once my car warms up the sound is gone sumtimes when i start my car and rev it as i start the engine theres no sound just when i wake up and just start it up then it makes a weird noise and i think you guys are right i thought it might be my belt too it prob is will toyota fix it under warrenty?

Maybe someone stuck one of those 'make your car sound like it has a Turbo whistles' in your tailpipe when you weren't looking.

*ducks*

Toyota replaced mine. What year is your car?

maybe its your Intake, have someone gas it lightly and you stand outside and listen to where its coming from, that would be your best bet to locate the problem.

timing belt problem... common with gts

get it replaced
