Prius (Gen 2) :: 2007 Whirling / Vibration Noise Coming From Engine Compartment (with Audio)
I would describe the noise as a whirling/vibration sound that can be heard as soon as the gas engine portion of the car kicks in (even in park) but gets louder and more noticeable as the car is in motion, especially at highway speeds (55 - 65mph). Opening the hood and listening to the engine block, the noise is definitely coming from around the area of the silver-covered portion by the driver's-side, which I believe is the hybrid synergy engine. The noise has gotten to the point where I really get bothered by it driving anywhere, and I have to turn up the radio to try to drown out the noise.

2003 Toyota Camry LE 4 cylinder
I am experiencing a loud noise which is getting worse from inside my engine compartment. I took off the heat shield assuming it was coming from the exhaust manifold but it is not. It sounds more like it is coming from the intake manifold. Now I would assume it was the intake manifold issue that has been described in many threads but it is not a vibration or clanging sound. It just sounds like air is escaping from my intake. What baffles me is that the sound is loudest in drive. Then neutral is the next loudest, then reverse there is very little unordinary sound.
I hear it a little bit when I am going like 15-20 MPH in reverse and let off the gas to decelerate. There is a noticeable noise increase just at idle too. I checked and all fluid levels are good. I changed the tranny fluid about a month ago and according to the dipstick it is right on where it should be. The sound is increasing and I am worried about what it may be. It sounds as if it has an exhaust leak but I do not see anything.
Lexus GX 2004-09 :: Tapping Noise In The Engine Compartment - Steering Vibration?
In 2010 i purchased a 2005 Lexus GX470 w/ 52k miles. It had 2 previous owners and you could tell it had been garage keep and most likely not their weekday car because low miles and 3rd row was in mint condition. Up until late last year the car has been great. I use it to tow my boat and the only thing besides regular oil/filters and its 60k checkup was to replace the drive shaft for the TSB/clunk noise on stopping.
I am currently having two issues that have been becoming worse.
1st is the knocking or tapping noise in the engine compartment. Below is a link to the video. This was after driving for approx 15 minutes. It doesn't do it 10/10 times, but is probably happening 1/2 the time now when i drive it. Oil is 10W30 Full Synthetic by MobileOne and just replaced today to see if that changed anything. I purchased 2 replacement knock sensors a few weeks back but haven't had the time to break it down to swap them out. Figured since the belt needs to be done at 90k and my car is 10yrs old I might as well replace the timing belts at the same time. When the AC is on or car is in drive it doesn't knock strangely enough. In the video you can hear the AC click on/off and knock when its off. I'm hoping this isn't a bad engine or rod or something... Thoughts?
2nd is the steering vibration. I noticed there is a TSB on that for replacing the steering column and other parts and assume I should do thing soon as well. Depending on the payment or temperature it will do this at times around 60ish MPH. Again, its not consistent, but is very noticeably while driving when it is. Tires have approx 40% tread remaining and only the driver side tire seems slightly more worn on the inside than the outside.

View 3 RepliesAccord :: Throttle Body Vibration - High Frequency Rattle Noise Inside Engine Compartment
So I'm at my wits end trying to locate (and fix) a loud, high frequency rattle noise inside the engine compartment.
It can be heard when applying the gas pedal a certain amount. In other words, I can "find" the noise and maintain it at a certain rpm.
The noise is coming from the back of the engine near the firewall. It feels and sounds like it's coming from the throttle body plate and vibrating the gas pedal. I cleaned the plate and it isn't loose.
The issue doesn't seem to be affecting engine performance.
The sound is noticeable while driving (under load). When in park, I can find an rpm where the throttle body seems to take a heavy wave of vibration from the engine and hum (but not nearly as loud as while driving). Issue existed before I put on new motor mounts, and still persists after replacing all 4 (although the vibration and noise are reduced).
Camry :: Rapid Clicks / Clacks Sound Coming From Engine Compartment / Firewall Area
I've had a used 2007 V6 Camry for about six months now.
I recently started noticing a quiet set of rapid clicks/clacks sound coming from engine compartment/firewall area more or less on driver side. I'm not sure if it was there all along or if I just began noticing it.
It occurs after starting the car, putting it in drive and as soon as I let off the brakes and begin rolling. It might only happen going forward. I will have to notice if it does it in reverse.
It happens rapidly and stops and I don't hear it again until I repeat the steps above after the car has sat a while. I don't believe it will do it again, if say, after doing it once I stop, put it into park and then back into drive and go.
I don't believe it's the CV joints. It does it once and stops and is not related to movement of the steering wheel. It almost reminds me of a relay switching something.
I'll also add that I had a 1995 Prizm and 2000 Corolla that did the same thing. Both were manual transmissions. The click they made was much louder though their cabins were not sealed as well as the Camry. The clicks would happen only after the car had sat a while as soon as the car first started rolling and then would stop. Could it be the same thing in all three cars?
Prius (Gen 2) :: Noise Coming From Engine Compartment After Shut Off
I started noticing some strange sounds coming from the engine compartment after shutting off the car ( a 2007 with 90K miles). It's different from the hum for several seconds that I often hear after switching off the car. This one is a squeaky rough sound like a small motor wearing out. I think it's from the driver side of the engine compartment. Is that where the inverter pump is? This car didn't have any record of needing the inverter pump changed for the recall as far as I could tell.

View 3 RepliesToyota - 4runner :: 2007 - Low Rumbling Noise Coming From The Engine Compartment
So, I have 100K miles on a 2007 4Runner (V6) and after having my radiator flushed at the Toyota dealership service dept, I get my car back and now hear a low rumbling noise coming from the engine compartment. I hear this noise every time I turn on the air conditioner, and sometimes even when it's off.
I took my car to Toyota today and after getting the service advisor to acknowledge the noise, I get a call 2 hours later saying, a) that no noise was identified by the technician; b) nothing wrong with my car; and c) I can come pick it up.
It ain't my imagination. Clearly, something is wrong. What it is? Should I take it to another service department? This kind of thing makes me crazy!
Pontiac :: Persistent Ticking Noise Coming From Inside The Engine Compartment
I have a 2001 Pontiac Grand Am with about 160K miles on it. Over the last month or two I have noticed a persistent ticking noise coming from inside the engine compartment. It sounds like it might increase in frequency along with the engine speed. It is loudest when I pull up in a drive-thru or next to another car and roll down my window. It is audible when sitting or while moving. Doesn't seem to make a difference if the car is hot or cold. I checked the oil and it appears to be full. It sounds like it's coming directly out of the engine block itself. I get the oil changed every 3,000 miles like clockwork.
View 3 RepliesPrius (2004-09) :: Strange Noise Coming From Engine Compartment / AC Unit
I first noticed a strange noise coming from the engine compartment a day ago. I had left the car to sit in the sun for a few hours. When I got in the A/C was set to on and the system was on auto. I tested to see if the noise went away when I turned off the A/C and it did. I turned it back on and it returned. I know the A/C operates at different speeds based upon cooling needs and that it can get sort of noisy but I didn't think that it could/should get this loud. The system seems to begin working quickly and it does seem to put out cold air. If the noise is unusual do you think that it indicates another underlying problem in the A/C system?
Just to clarify, the ICE is not running in the video. The cabin fan is set to low and the temperature is set to low. The person in the car presses the A/C button and the cooling fans in the engine compartment come on as well as the A/C unit. The sound gets louder a few seconds in. Here is the link to the recording I made of the sound.
Corolla / Matrix 2009-13 :: Rattling Noise Coming From Engine Compartment When Drive At 60+ Mph
I have a 2009 Toyota Matrix S. There is a rattling noise coming from my engine compartment whenever i drive 60+ mph. It sounds like it's metal on metal. Nothing is loose inside. I took it to the dealer and they told me the water pump bearings were bad and replaced my whole water pump. That didn't resolve my problem. The rattling is still there.
View 2 RepliesToyota - Rav4 :: Rumble / Whoosh Noise Coming From Front Engine Compartment
Rumble whoosh noise (her description,,, I am currently in another State) coming from my wife's vehicle in the front of the engine compartment. Closer to the passenger side near the water pump. Noise has been present for the last six months, but would always go away after it was warmed up. During winter (In Tucson AZ so never gets too cold), it is worse due to the cold weather. Previously only happened at low RPMs and ended to be worse when turning a corner.Today it occurred also after operation for a quite beyond starting of the vehicle, and is starting to sound like the failure of bearings. Also a burning smell was occurring.Just replaced both the water pump and the alternator, and the front struts. The water pump is not leaking but the old pumps leaks are still evident. The current mechanic trying to troubleshoot is stumped. Motor mounts are getting close to failure, but still appear to not be a problem. CV joints are fine. What to look at?

View 2 RepliesToyota - Sienna :: 1999 - Whirring Noise Coming From Center Engine Compartment?
I own a 1999 Toyota sienna that has 112,000 miles. For the past few months there has been a whirring noise that seems to be coming from the center engine compartment. It started quietly and now has increased in volume. It reminds me of a speedometer cable that is beginning to fail. I have taken it to my trusted mechanic for a diagnosis and he thought it was metal on metal noise from the transmission. I have owned cars for 40 plus years and have'nt heard of this type of tranny noise. What could be causing this? It makes this noise under power and when I release the accelerator the noise almost disappears. Also there is a clunking noise coming from the passenger front wheel after releasing the brake pedal when I come to a stop. I have replaced the strut,ball joint,and lower control arm bushing trying to remedy this. I cannot find anything else that is loose.

My 04 hyundai accent about 2-3 months ago acquired a hissing noise which seems to be coming from the middle of the engine compartment. The car only has 100,000 miles on it.
It is a constant hiss that only stops when the gas pedal is pushed initially. I have looked all over the car and can not see any fluids leaking at all. It is pretty loud and can be heard easily outside the car when the car is on.
I hooked up my obd2 reader and found these codes:
P0304-Cylinder 4 misfire (I notice it when the car sits at idle for about a minute)
2x P0121- Throttle Position circuit range/performance problem
2x- Evaporative emission incorrect purge flow.
Camry :: 2003 - Bad Engine Noise Coming
I just acquired a 2003 Camry LE 2.4 with 143K miles on it. most everything on the car is in great condition, but I am getting bad engine noise at about 1500 rpms and higher.
It sounds like I may have a spun bearing, but am not 100% sure.
The oil filler baffle is still in place -
What is the best way to diagnose if a spun bearing is the problem?
If so, what are my options?
I was thinking:
a) get a replacement motor
b) repair the one I have
c) scrap the car
Although I don't need the car immediately, I also don't have a closed garage to work in (2 project motorcycles in pieces and nowhere for a car at the moment) and have never pulled an engine out of a car before or done anything in the lower part of the engine.
I am comfortable checking valve clearances and other maintenance - On my 96 Camry I have replace the front suspension, shocks, gas tank, all fluids/filter/hoses, harmonic balancer, alternator, starter etc. - but not too sure about engine internals.
