My brother and I noticed my engine making this noise today, I was under the hood and he was giving the engine gas with the car in neutral.
video of sound: [URL] .....
Sounds like air pressure being released, sort of a quick whistle or squeal just as he pushes the gas pedal, coming from under the hood somewhere.
When I take my foot off the brake, there is a squeal or whistle. It's sporadic and sometimes loud and long, other time low and short. It doesn't seem to happen when the mechanic is driving. And they can't determine cause.
View 1 RepliesI ran over a parking stone last summer, ripped the plastic undercarriage a little, but alignment was fine, wasn't that bad, etc. I took the car to the shop last week for a strange whistle/squeal on acceleration and letting off the gas (PCV valve under recall) and they stated that my radiator support was broken, and the radiator was hanging there to the tune of 750 bucks.
View 1 RepliesThe title pretty much explains it. Coming home today started hearing a squeal/whistle while at highway speed - almost sounds like the brake wear indicator tabs that GM is so fond of. Thought it might be the brakes, but it didn't stop with brake application and continued after coming to a full stop. Also, surging at idle, which seems to be reduced when the A/C compressor is on. The squeal happens both with and without A/C.

I have a whistle sound mostly upon decel when the engine was cold. I have the APR down pipe installed. Today it's doing it all the time even when warm. I took the car to the dealer and they said it was prolly an exhaust leak. I took the car to my friends shop and we put the car up on the lift and listened from underneath. It sounded like the turbo was echoing in the down pipe. Sometimes when it's cold it can be very loud. So my question is if this is normal with the APR down pipe or with this turbo or is this a sign that I have a turbo failure coming?
My truck started making this whistling sound a few thousand miles ago. Its a high pitched squeal coming from somewhere under the hood. There doesn't seem to be any pattern or certain time when it does it. Ive read on here about an alternator problem on these trucks. Or could it be my S&B intake?

I have recently developed a slight whistle/squeal when boosting and when letting off on the pedal. I initially thought I had a CAC boot starting to split out, but since it's making the noise when I let off as well I doubt that the problem.
It isn't constant, and only does it for a second or two when it happens. It's not extremely loud, just loud enough to make you wonder what the heck it is...
I am due for an inspection for a 2004 Camry (4 cyl.).
I had the engine light come on with a P2231 or P2238 code on my OBDII tool. Car was running fine, no weirdness whatsoever. But I went ahead and changed the front sensor (Bank 1 Sensor 1). As soon as I changed the code went away and it is not coming out anymore, nor are other codes.
However, the engine doesn't idle after 5 minutes running. I have to keep revving it up at the light to keep going. I shut it off and it turns on no problem. But then it doesn't idle. What a pain, I used the Bosch O2 sensor bought from AutoZone.
It's a 96 850 Naturally Aspirated. There is a whistle sound (usually about one second in duration) when I let off the throttle.
Based on what I've been able to find out so far it is most likely at Vacuum line or a gasket somewhere in the intake line. The more common source of this is the Throttle body gasket but that doesn't seem to be the case.
I think the sound is originating on the left portion of the engine, somewhere between the oil cap and the timing cover.
Any good ways to test the vacuum lines or gaskets?
In my 2007 Sonata, I hit a poorly placed high manhole cover in a dip in the road, in the dark, going 30MPH, whacked it good before I could adjust...
I then pulled the car over, it seemed to go dead, then the car did crank back up, the engine sounded much louder, like a loud rev/hum, not quiet like usual.
I next drove a mile to a c-store, transmission seemed OK, no leaks, did see a check engine light briefly, but it disappeared. Car cranked OK, headed home, same sound right at cranking and at moderate speed.
Finally, I jacked the car up on the front left, from research appears that the plastic engine shields got smacked good along the front and near the right tire and bent back quite a bit on the left side. There seems to be no other structural damage that my untrained eye could see, just one indention you'll see in a couple of the photos that I think is part of the car design at that spot.
Again, no leaks, no smoke, no caution lights of any kind now.
Photos are attached...
My Hyundai's engine now sounds like a Mustang! Hoping it's just the engine noise from these plastic covers now being bent/destroyed in some spots, exposing the engine and the typical noise you'd hear without them...
Earlier today on a easy drive (not pushing it) I noticed a slight "whistle-sound" that I haven't noticed before. About then it became VERY sluggish and the Engine Management Light started to flash.
As soon as I could I pulled over and connected my AL619 and it says "to low turbo/supercharger flow".
I didn't notice any smoke or smell, just a serious lack of power (i was doing 30km/h at the top of the hill).
Just tried to locate the leak, but I cant feel it or see it. I guess one would need one of those "smoke generators" to see where the pressure goes out.
So, do I have a broken turbo, or just a blown turbo pipe/tube?
99 Chevy Astro with 93000+ miles. Only recent problem (one week ago) was left lights on for 4hrs on a new battery and almost completely drained battery, then, vehicle cranked without a jump. This AM started van to go to work and there was a definite "whirring noise" from under the hood. Popped the hood and sounded like coming from the brake master cylinder area vs. AC compressor area-hard to tell though. AC has not worked for 2 yrs. Noise increased in proportion to revving of engine. Likewise, noise continued while driving, although seemed to not be as loud when engine warmed up. Temp outside 34. Fluid levels OK. Where the noise is coming from? Also not sure if related or a concern: brake pedal has a slight "stick" to it when initially pressing the pedal, for ~ last 6 mths. give or take Brakes seem to work fine.
View 2 RepliesSo I just took my 2010 Camry xle-4 in today for brakes and a squealing noise coming from the engine compartment, 76,000 on the odometer. Thought they were going to tell me one of the two belts needed to be replaced and to my surprise they tell me it is the transmission. If you put it in park the noise is gone. I have the 100,000 Toyota backed extended warranty. the tech stated what I did not know until today - sealed transmission. They had to requested an adjuster (warranty requirement) to come out and look at the vehicle prior to ordering a new transmission - no repair option. Vehicle shifts with no issues, drives fine.
View 1 RepliesI have a 2011 Camry 6 speed Manual Transmission and every so often when I shift gears I hear a squeal noise in the engine right as I fully let off the clutch and give it gas in the next gear up. It usually does it when shifting to 2, 3, and 4th gear. Any other Manual Camry owner with this issue that might know what it is? I never really hear it if I take off slow or shift at a slow/normal pace, but if I'm in a rush and have to pick up and GO then most likely will do it.
View 4 RepliesI bought a CPO 2010 Camry LE (2.5 4 cyl, 6 sp auto) a few months ago. The car had around 34K miles when I got it, and ever since then, it has had a high pitched whining noise when accelerating or revving the engine in park. It is noticeable from around 2500RPM up, and seems to be a little louder when the engine is cold.
I have left it at the dealer twice, and both times they have come back and said it is normal. I can't believe this, because I have owned many cars over the years, most of them being fairly dilapidated, yet most of them haven't had a noise like this. I think I have read a comment online somewhere that an issue like this was found due to a bad power steering pump .
I have a 1994 Toyota Camry. Took it to a shop to repair an oil leak. They had to dismount the transmission to get to the gasket. I got the car back and the transmission was messed up. Took it to a transmission shop and they told me that the transmission "cable" wasn't positioned correctly by whoever had done the work and they could fix it. They told me it was safe to drive it until my appointment. The engine was revving too high before changing gears and while driving home, I heard a loud rattling noise in the engine and my car stopped in the middle of the road. I'm told that a rod has broken inside the engine. My question is: can this in any way be related to the transmission cable not having been set/positioned correctly?
View 5 RepliesI've searched but it seemed to lack a definitive fix. One mentioned felt glued into a crevice behind the mirror, but was not very explanatory since the pictures which were needed to understand where things went have since gone dead.
View 5 Repliesjust noticed when i cold start my car the turbo makes a whistle noise until it warms up and when i drive hard when its spoiled it makes that whistle again......
View 3 RepliesOn Tuesday July 16th was driving along AC was on and all of sudden I heard a squeal coming from the engine compartment. The AC stopped blowing cold air then the A/C light started the flash (manual Air conditioning). I turned off the AC and finished out my day with the windows open.. I have read the post about the flashing A/C light but I am wondering if I should address the squeal 1st I only hear it when the A/C is turned on.. 2006 Camry V6 137K miles.
View 3 RepliesOk, my question is, when gas pedal is pressed half or more down-ward, a squeal sounding is coming from engine compartment. 2003 ranger v-6 3.0 flex....
View 1 RepliesI have a 2011 Camry LE with American Racing aftermarket wheels. I had the car serviced last Saturday for its 70,000 mile check. When I got in the car to drive home, I felt that somehow the car was making a different sound and did not "feel" right. I did not drive the car for a few days, but when I did the left front wheel was making a grinding sound, checked underneath, for any kind of debris I might have picked up. Nothing. I took it back to the dealer. They put the front wheel on the back and the noise and vibration were gone. They said it was a defective hub on the rim. Then tonight, coming home from work, the right side was making the same sound or worse. I pulled into a tire service center, had them do the same to that side, and the sound and vibration stopped. A friend thought it might be the weights have moved and due to the tighter spacing on the front wheels they are hitting the calipers as the wheel moves.
