Camry :: 2007 SE V6 - Metallic Twirling Sound When Engine Idling
Jun 14, 2012
I am the original owner of a 2007 Camry SE V6 with 95K miles.The car has been meticulously maintained. About 2 weeks ago I started to notice a mysterious sound coming from the passenger side of the engine ONLY when the engine is idling. It has a higher, light pitch but when revving the engine slightly it goes away. Obviously when driving it can not be heard with all the other road noise etc. Also it makes this sound at different times, sometimes days with no noise, very irregularly. I checked that section of the engine bay and see no moisture, leakage or discoloration anywhere. Also serpentine belt shows no wear or wobble. Could it come from the water pump? I am very concerned that something will soon snap off, break and leave me stranded.

I have a 2001 Saturn SL2 1.9 liter DOHC. I am getting a metallic rattling sound from under the car. The sound happens only at certain RPM idling speeds; what could this be?

I had a previous post regarding this when it started, but it seems to have now changed. Twice this morning, both while idling still in traffic, my engine stalled. Turning the key it starts right back up and runs fine. I'm hoping that it doesn't morf into stalling at speed.
Originally this happened 2-3 times a couple of months ago. It would die and then catch itself and keep running. Again, each time while idling in traffic. Once or twice it also seemed as though it was ignoring the throttle request for just a second, then took right off.
Two things come to mind, and OBTW, no codes thrown ever. What do you think about throttle position sensor or gas pedal issues! I'm wondering if it's losing track of throttle position and taking it to a low level and a stall?

I have an '09 Camry and for the last few months have been hearing a metal popping sound in the rear wheel area when I go over a bump or pothole unevenly or backout of a driveway at an angle to go onto the street. The sound does not occur when the wheels when they are even, only when the rear right wheel is "lower" than the left. It has not been in any accidents and there was no event that preceded this popping. I took it to the dealership but they were unable to replicate the issue but it happens no matter who drives the car (my husband or myself) and it is likely that the service guys didn't go over any bumps/curbs/potholes unevenly to hear the sound. They check the axles and said everything was good with the car but it is still popping and driving me nuts.
Current suggestions:
• Cracked bearing race. It could be another problem entirely having to do with the suspension mounts or axle mounts but let's hope these new mechanics will figure it out.
• Problem with a wheel bearing
• Struts and suspension components
• Bushings and parts
• Loose upper strut center nut or from loose upper strut mounting nuts
I took it back to a shop but they are thinking the sound is actually coming from the body near the roofing area in the right rear portion of the car. They seem to think based on the sound (metal popping only when that wheel is lower (like coming out of a driveway angled, or going over a pothole)) that it is the metal body but it would cost and arm and a leg to get in to even find out what it was. They assured me that it wasn't impacting the safety of the body and is just a funky sound. The sound is much louder in the car than outside which I think kind of supports their theory. Are they right and it won't impact the safety?

Where this sound is coming from? I notice it more when the engine hasn't been turned on in a few hours or so. It only happens at certain engine rpms, usually a bit higher than idle. It's a bit squeaky, per se, may need to turn up audio on the video below to hear it. May need to bring her in (just did a 30k service too..)
Possibly a belt of some sort? My AC is on at startup.

When accelerating up a steep grade the engine will ping (rattling metallic sound) when reaching a certain RPM, but stop pinging as I continue to push the accelerator down and increase the RPM. Should I be concerned? Could it be something else, loose exhaust heat shield or something? Or is this normal behavior for a gasoline engine? My old Honda Fit never had engine ping/knock that i can recall in its 200,000km of service running the same 87 octane gas.

I own a 2011 Hyundai Sonata with ~40,000 miles (certified pre-owned). I heard a metallic pop sound while driving but did not see anything on the road or in the rear view mirror. Then I got on a highway and couple of minutes later there was no response from the engine (i could feel the car decelerating). Then the engine started responding again. A couple minutes later, again there was reduced response but this time I got a bunch of lights (oil pressure, abs and a few others). I pulled over and tuned off the car. by this time only the oil pressure light was on.
I checked the oil which was near empty. I walked to a nearby gas station and bought oil and filled 2 quarts. Then I noticed that all oil was draining right through in a steady stream.
I had the car towed to a nearby Hyundai dealer. The dealer diagnosis was that there is no drain plug which may be because the last place the oil was changed (around 2-3 months back) did not install the plug properly. He also said that the engine is ruined and will have to be replace and asked me to contact my insurance company.
The last oil change was also done at a Hyundai dealer (a different one than the one that provided diagnosis). I checked my driveway and there are some oil stains, I haven't driven the car much recently and have recently moved into this place so am not sure if these are new or old. What are my options. I don't have the the thousands required for a new engine.

So I started getting this metallic/harmonic whining sound from my GTI's engine a few weeks ago. It was barely noticeable then, but has now gotten louder and more consistent. The sound occurs once the engine has warmed up and can be reproduced by holding the revs constant anywhere above 2k. The sound does not change in pitch with engine speed. It doesn't matter if the car is parked or moving.
I've attached a video... The sound can heard starting at 00:23 and becomes constant after a few seconds. Its hard to hear at first, but if you listen carefully its definitely there.
I have an appointment with the dealer tomorrow and will update with their findings. In the meantime, any clue as to what this could be? I can't really pinpoint where its coming from, seems loudest near where the oil filter is? By the way I'm 100% stock.

I am having camry 2007 with 100 k.miles running. When engine crosses 2000 rpm, I can hear a tik tik sound from engine. This sound is not coming when engine is cold, and also when the engine is on acceleration.
I have checked alternator and A/C bearing. It's OK. I have also replaced timing chain tensioner.

When the engine of my 2007 Camry LE V6 is cold, it makes a ticking/knocking sound. The engine has 100,000 kms on it (60k miles). The frequency of the sound varies with the speed of the engine, not with the speed of the car.
When engine is cold: The sound happens roughly twice a second when the engine idles (at 700-800 rpm).
When engine is warm: The noise is less audible. It can be heard when idled at a stop, but you have to listen for it. The noise cannot be heard on the highway.
The car doesn't burn oil, and the oil level is ok. I had the oil changed 3000 kms ago, and it is still very clean (clear). The was the same before and after the oil change.
I am wondering if it could be the lifters, bad plug, or maybe a timing issue.

I've a 2007 Toyota Camry (LE 2.4 L 4-cylinder). Couple of days ago I tried to start the car and I heard this banging/grunting sound as I started the car. And, after the car started the engine is running much louder. Oddly enough when I got out of the car and opened the hood the noise didn't seem that loud. In other words, it sounds louder from inside the car than standing outside with the hood open.
Before all this, the engine ran very smoothly and very quite. Here is a link for two audio files that captures the sounds. Note that I recorded these two clips from inside the car.
First when is when I'm starting the engine (the sound can be heard at around 6-7 seconds): [URL] ....
Second is when the engine is running loud (I'm not driving the car...just sitting there letting the engine run): [URL] ....

My 2009 corolla recently started producing a brief metallic sound (less than a second) when i start in a cold morning. I noticed that when I warm up my battery (by starting the heat ventilator or other electrical equipment) for 10-20 seconds the car starts normally. The other thing I noticed that I have some white powder deposits on the top of my battery. There is no any other changes in the way my car runs.

Problem description: A loud metallic rattling sound from under the car under moderate to heavy engine load, only when engine/exhaust is/are cold. It is noticeable from within the cabin with the windows rolled up and the sunroof closed. Crack a window or the sunroof and it's pretty loud. The first time I heard I, I thought "this is not good".
This is not an octane ping or valve train noise. It sounds like a coffee can with marbles being shaken in concert which what might be the rapping of a V8 engine's exhaust. I had a Sunbeam Tiger that rapped in the upper rpm ranges and this reminded me of that but instead of rapping, it shakes a can with marbles.
There has been much discussion and speculation as to what causes this. It does seem to occur only with late - 04 and up V8 Touaregs with the "sport" exhaust that replaced the "std"(?) exhaust used on the majority of the 04s.
Observation: I looked very closely at the heat shields, looking for ways they could rattle. On the passenger side (LHD), the heat shield has three main sections:
- Front: around/near the secondary cat (tightly secured)
- Rear: around/near the rear differential (tightly secured)
- Middle: between the two mentioned above (loosely secured)
The three sections overlap a little where they meet. It was very easy to tap on the middle shield and make a loud metallic sound. I put my finger between the two shields (where they meet) to isolate the two metal pieces and tapped again, and the noise was gone.
Theory: The harmonic resonance of the exhaust under load vibrates the middle heat shield and it rattles against the front and/or rear shields. As the shields heat up, they flex enough to provide clearance between each other and the noise goes away. This may be unique to the "sport" exhaust if (and I am only speculating) the heat shields were changed (in design or fitment) when they changed the exhaust.
Experiment: I tried a very simple experiment. I slightly bent the edges of the middle shield (~1/2 inch) where it was coming in contact with the front and rear shields. The allowed me to tap rather hard on any of the shields without them rattling against each other.
Result: I make the tweaks to the shields Sunday night. When I drove to work this morning, I put the transmission in sport mode and ran WOT until it shifted. Normally, I would have heard the sound (very loudly) but it was gone. No metallic sound. Not completely convinced, I repeated the experiment on the way home and, again, the sound was gone.
Summary: It was cool out when I was going to, and from, work (64F) and this would normally be the perfect set up for making the sound. I think that tweaking the heat shield has solved the noise on my Touareg. I am tempted to go back under there and pop-rivet a little brace between the shields so that they cannot rattle against each other again. On the other hand, I may just leave it be and do the pop-rivets if the noise comes back.
Anyway, I was excited to find a potential solution for my Touareg and wanted to share it will you all. I will post back after a while and report how it goes in the long term. Lastly, I really liked being able to put the air suspension in xtra-offroad and get under the car (easily) without using a jack....

I recently purhased a 2012 Camry, and hear a crackling noise from around the exhaust area as soon as I start the car and during idling. The noise is not too loud, so can be heard from the driver's seat only if the AC is off, windows are down and if the outside environment is relatively quiet. However, when I get out of the car and stand near the exhaust area, it is quite audible. Drove 4-5 miles and stopped and the noise still existed during idling. I'm not sure if it exists while driving as it may not really be audible at the driver's seat. Is this normal or do I need to get it checked.

I have a 2007 passat and it makes a whistling sound while idling or when I am driving except for when I am actually pressing the gas. Additionally the EPC and check Engine lights came on. What the problem could be? This is my first VW and I am really just use to Honda.

My 2007 Hyundia Santa Fe has an erratic knocking/clicking sound when idling & has for about 6 months or so. Other than the clicking noise it drives just fine. I am wondering if this may be a result of a bad oil change experience I had in 2012. I'll explain ....
When driving home, once the car had warmed up, my oil pressure warning light came on whenever I came to a stop or idling. I thought this was strange but thought maybe it had to do with new oil fill & would go away.
All I knew was I didn't have the problem before the oil change - nor have I ever in all the time I have owned the car - seen the oil pressure light come on and stay on once the car is started. So I brought the car into Hyundai as soon as I could to explain the situation. They opened the oil filter compartment and quickly realized that whoever changed the filter neglected to put back a part that sits on top of the filter that regulates the oil pressure (only a $15 part without which the damage & cost of driving without is potentially huge).
There is more, but I think you get the drift. So, I am wondering if possible damage as a result of that faulty oil change might have something to do with my current problem or is it not possible given the time/km between when that happened and now? The car had just over 80,000 km at the time and currently has aprox 105,000. I have properly maintained the oil etc since that as well as prior to.

I have a 4-cyl 2007 Camry XLE. I changed out the plugs, simple enough. but now the car seems to be idling too low, just a tick below 500 RPM. Its causing some minor vibrations as also the AC is not working at a stop, it just blow warm air. As soon as i push on the gas the RPM jerk up pretty sudden, the air pressure from the vents increases and its cooler. So it seems the AC issues is related to the RPM being too low so once i get the RPM's back up it should be good to go.
These are the stock Denzo SK20R11 plugs that were in the car : [URL] ....
And these are the equivalent NGK IFR6T11 plugs i put in [URL] .....
So, I thought maybe because the ECU got reset maybe some re-calibration, but I have driven a good 100 miles on it and no change so i doubt that's it.

I have a 2015 IS350 F-Sport. While accelerating, the engine sounds fine, but it sounds aweful when idling. Don't know how else to describe it other than like a rattling sound...it's just not smooth. Is this "normal" or should i schedule a service appt for my car?

I was driving this morning after doing a brake job (nothing to do with the problem, just anger coming out) made it about 10 kms and noticed when i took my foot off the accelerator, the heater fan powered down a bit, and back up when I gave it gas...noticed a knocking sound from the engine...pulled into a gas station and put it in park. After a hard time idling, it cut out. I started it again and the idle was not good at all. kept cutting out. Got it going and made it home with the same sort of power issue. Tried to start it a couple times and same issue with the idle. Sputtering quite a bit and noticed quite a bit of exhaust coming out. When I backed it out of the garage, I noticed a small puddle of oil.

I have a 2009 with 45,000 miles. It has been idling goofy for a while. Last winter when it was cold it the engine when first started would jump around between 200 - 800rpm when idling. I went and had the fuel system cleaned. It wasn't noticeable when it was warm out and it did not jump around as dramatically on cold starts. Lately it started bouncing on every start from 400rpm-800rpm. It drives fine, just idles bouncy. The other night it lost power while driving. The engine was running but when the accelerator was pushed it would not speed up. It was limping along at 20mph and the engine light on the dash turned on. After sitting for little bit, the engine light was off and drove normally again. I have an apt. for the dealer to look at it next week, but of course I will not be able to recreate the event and there are no error codes.
