engine noise??

[poshi]

hello everyone..

anyone have this problem? my yaris... everytime when i shut down engine and walk away from my car, i can hear the "dit-dit-dit" noise from my engine or somewhere under the hood.. it stays there for quite a while..sounds like something is turning and hitting something and after a while it stopped... anyone have similar problem? my car is about 2.5 wks old and about 2000km ODO now..... i hear this since the first week...

Nothing to worrie about.. its the metals cooling down.. thats what I was always told.

[PixieDawn]

I remeber when I picked up my yaris there was this sticker on the glove box..saying something about after the car is turned off it tests the gas tank for leaks or something and you would hear a noise..

I will see if I can find the sticker when I get home from work

my cars have always done this, but i haven't heard the yaris do it yet...weird.

Ive had that noise before on exhaust manifold shrouds and electric cooling fans continuing to run after the engine is off or if the temp is ok the fan slowing down.

Usually it is the exhaust cooling down. It is normal.

Th popping kind of noise I have been told is the oil dripping back down in the oil pan. I am a diesel mechanic and we hear it all the time, and it can also be the metals parts cooling down as stated in another post.

and i think the gas tank thing only happens 5hrs after it has been sitting there. and ya its either the oil dripping into the pan or cooling metal. I hear a weird noise when I'm in reverse, like a heatshield is loose and it only happens in reverse. Anyone else hear this.

Deafness precludes me from being paranoid!

[boxerboy]

Don't worry about it. I have heard everything from bulldozers to motorcycles do it.

I have heard that kind of noise coming out from other cars (under similar situations) too. I believe there is no problem.

I'm hearing this everyday when I back out of my driveway. I thought the same thing, sounds like a heatshield or something rattling for a couple of seconds. It's only in reverse and I only notice it when it's first started up.

I get a "rattling" sound when I put my car in reverse. Don't have to be moving, but it also makes the sound when I'm backing up...

[rstb88]

ya and i have no idea what it is and its driving me nutty

[swng]

Re the last two posts by Dawn Eshelman and rstb88.
I have heard the same rattling noise too. I mentioned it to the service adviser the last time I took my car to the dealership for oil change. I guess the problem did not occur there and so nothing was done. Sometimes, I still hear the same noise when I engage the reverse gear whilst stepping on the brake.

[poshi]

oo icic thx for everyone's input. i brought my car to the dealer and they told me the same reason too, but is there anyway i can avoid that? it is not bothering but it is just weird that it doesn't happen to my other cars

I have heard this noise on two different cars in the past, both toyota...one was an older corolla(1990/1999) and the other was a 95 camry... both were the motor mounts going bad. When in reverse the motor mount lets the engine rub against the mount and causes vibration on the car and if it gets bad you can feel it in the steering wheel. But these are newer cars so I would hope that is not the problem but might be worth checking out. I can tell you how I found it on the cars, if you care to know just ask...thanks,abattle

[rstb88]

go ahead and send me a pm on how to check and see if the mount is being rubbed. cause that'll give me a reason to look at the suspension as well.

i'm hearing noises when i'm backing up it's like a sound of fan blades hitting a string or something....do you hear the same thing guys? my yaris sedan is only week old 300+ mileage...:confused:

I guess u have the automatic transmission.I have the same problem when I select the reverse gear(manual transmission)

[fox racer]

im a diesel tech and im pretty sure the "dit-dit" or clicking noise u hear when u shut the car off is the thermostat in the engine poping in and out, cause once u shut the car off, everything is off, even the cooling system... so bsically the engine cooks itself, its alright no need for alarm, my dodge dakota, my chrysler cirrus, my girlfriend's '88 buick lesaber does it... to eliminate that sound... just dont pay attention. hope that helped

I hear the same noise too. I mentioned it to the tech when I went to the dealership for my first oil change about three months ago. Apparently nothing was done that time. May be I will mention it again when I go for the next oil change.
The strange thing is sometimes I hear it when I switch to the R gear, sometimes I don't.
Since nothing serious has developed, I am now ignoring it. I don't know if it is right to though.

The noise in reverce is annoying but normal and completely harmless

The cause it the exhaust and the way it's suspended under the car.
When the car is in forward or reverce it torques/twists the engine in one direction or the other. In forward the exhaust fits snug together, however in reverce they exhaust is being twisted againt it and a slight bit of rattling between the joints can be heard.
Don't worry about it, a lot of 4CYL/FWD cars do this
