I noticed recently that on my 2007 Camry i4 @ 110k miles, engine rattles pretty noticeably when I have the AC on AND while on reverse. Once I either turn off the AC or shift to D drive the rattle is no more. This noise is pretty consistent.
Not sure if this is a common problem, but could this be a problem with the water pump/alternator?
I got a 2007 Camry 2.4 l4 engine under the hood and its didn't start this until we had a garage change the oil never did this when toyota changed it. Mostly when the engine is cold started there is a little bit of a rattling noise it will make until engine is warmed up and once its warmed up at times it will still sound kinda bad when it runs at normal engine temperature but this mostly occurs on cold starts and didn't start doing it until a regular garage changed the oil this never occurred when toyota dealership changed it
I don't know what kind of oil that was used in it last at that oil change but it started that about a week or so after that. Car currently has about 133,000 something miles on it ... Its not that loud of a noise but its noticeable when all doors are closed.
My a/c has been slowly but surely going out. When it worked it would blow cold air, but it would slowly decrease the force that it would blow until almost nothing came out at all. Now it wont even turn on. The cabin air filter is new, the lights on the a/c and circulator are both on. I think the compressor is still turning on too. I did notice that occasionally it will make a quick hiss noise, but it happens fast, not a consistent hissing noise.
View 6 RepliesI recently obtained a used '07 Camry LE (2.4L with 120k miles) and thought to clean the throttle body when I changed the spark plugs. After putting the intake compartment and connecting everything back together (I'm assuming correctly), the air filter box along with the hoses seem to rattle a bit more. Today, I popped the hood after a short drive and discovered a on/off hissing sound -- it's possibly this sound started the day I worked on my car.
Thought I would post a video clip : [URL] ....
Just bought a 2007 camry SE v6 And there is a rattling noise when i start the car, it only happens on cold start up when the engine is hot it start normal.
View 1 RepliesMy mom drives a 2002 Toyota Camry with a 2AZ-FE engine and 180,000 miles on it. Recently she started hearing a rattling sound coming from the engine. She says the sound does not go away after the engine has warmed up. I took a short video of the sound. How to go about diagnosing the issue.
View 4 RepliesMy 2005 Toyota Camry has developed this rattling noise that is always there when the engine is on. When the engine is at higher RPMs, it becomes more noticeable. Here is a quick video I took of the noise for the audio of it..
It was too dark for me to check tonight to see if there is low oil or anything (there are no lights lit up on the dash).
My Camry has about 338K miles. Started making an engine rattling noise on acceleration. suspected worn timing components. I have all timing components off now. Of course plastic chain guides are worn, tensioner plunger seemed to be a little rough in actuation, exhaust cam sprocket does show signs of wear. I dont know for certain that replacing all timing components will clear noise. Questions are: considering mileage should i just replace all the timing components or the likely cause of the rattle noise(whatever that may be)? Should i replace the oil pump while i have pan off? How much trouble would it be to pull head and do valve job at this point? Lastly....2002 Camry has the 2.4 VVTI with the intake cam sprocket. How do i replace this sprocket and is it difficult?
View 14 RepliesI have a 2003 Camry 4 cylinder with ~143K. When I start the engine I can hear a slight rattling noise. When I rev the engine the noise seems to go away (or it is just masked). I noticed the noise after the check engine light came on twice and I had it checked by an exhaust shop. The code was for an O2 sensor, but the exhaust shop said everything looked fine to them. This was about 7K ago. I jacked the car up a few weeks ago to check the exhaust for anything obvious, but couldn't find anything loose to explain the rattle.
I hit the exhaust pipe with my fist and heard a rattle a few times, maybe from the catalytic converter, but I am not certain. Everything runs/operates fine, smooth acceleration, fuel economy is unchanged, engine temperature is unchanged, but the noise persists. I don't know if it is just normal due to age and nothing to really worry about, or if it is the first sign of trouble. I have also noticed that I am using about 1/2 quart of oil between changes, but I'm fairly certain that started before this noise.
I have a 2006 Camry LE 4 cyl. that developed a light, random (metal sounding) rattling noise under the hood, near engine on passenger side. It's present/noticable at idle and slow speed.
Car runs great otherwise and great gas mileage, pushing around 100k on odometer. Out of town with car otherwise would have looked at. Could something just be loose? Something in air filter? GF drove it down to FL and was fine before she left.
'02 V6 30v with 73k.. engine noise sounds like rattle consistent with idle sounds like its coming from rear section of motor. i did search came up with a few probabilities but no resolutions just wondering if possible it could be oil pump because if i add oil then start up the noise disappears for a few mins then comes back, a few guys mentioned it could be camshaft tensioner.
View 4 RepliesI have an odd one; there's a noise that sounds like an consistent electrical snapping noise coming from the engine while running. Everything seems fine otherwise. Just looking for possible things to check.

I'm looking at a dirt cheap Explorer 4.0, has been sitting for 2 years. Runs nice, with a double "knock" noise but quieter than a rod knock. Idles smooth at 600 rpm, "knock" is consistent, but increases as engine increases speed. Has 2 year old oil, and 2 year old gas. Would a tune up support it, and revitalize it, or is the engine almost dead. Still drives, didn't push it to hard. Interior is 9/10, exterior is 10/10. I have him down to 600. 4x4 works, and feels good.
View 6 RepliesI have a 2007 Camry LE, with about 104,000 miles on it. Lately I've noticed a noise ONLY when the car is idling, rather in park or drive. I don't hear it all when I'm driving. It's somewhat hard for me to tell if it's coming from the engine or under the car, but its definitely near the front and sounds lower in the body. My first instinct told me that it was related to the exhaust system, but it doesn't quite sound like a rattle. It sounds closer to a belt struggling to turn...it actually sounds a little bit like when my water pump and alternator went, but I had those replaced 15 months ago so I really don't think it's that at all. I also had the radiator replaced 2 months back, so I don't think it's that. I don't know drive far to work, so I haven't put a lot of miles on the car in the last year.
Otherwise the car drives normally, just hear this sound at idle. The only other thing I've noticed over time is that when the car gets to about 2500-3000 miles after an oil change, I notice the light flashes when making hard turns..but that's it, and it goes away when I get the oil changed. Obviously I know that the engine is burning oil probably faster than it should, but I'm not sure if that might somehow be related to what I'm hearing above.
Just recently starting hearing a loud roaring noise while driving my 07 Camry V6 XLE. It sounds like the gears are not shifting, like it is staying in low gear. Sometimes the sound will lessen if I'm driving over 15 mins. and some times it doesn't. RPM is around 2 or less, typically 1.5. Tried to check the transmission fluid but could find the stick. The car has about 142,000 miles. I hope the engine is not going.
View 1 RepliesI have a 07 Camry with i4 engine. It's making noise like the YouTube video link below. I only put around 35,000 miles on it so far.

I have an 07 Camry with an I4 engine and there are times when I am driving with the two front windows down and I hear a ticking/clicking noise coming from the engine as if the engine is brittle.
View 12 RepliesI have an 07 SE (manual transmission). In cold climates has noticed a noise at startup on a cold engine when the temperature is below freezing (colder than -5C or so)?
The engine has to be cold (like sat overnight) and the outside temp has to be cold. Then at start when I turn the key, the engine starts fine, but as I release the key from the start to the run position I hear what sounds like the starter motor make a noise (short zipping sound).
At first I wondered if it might be slow to disengage, but if that shouldn't make a noise because the gears should be meshed ok? There is no noise with a warm engine, or with a cold engine on a mild day.
My 2002 V4 Camry has developed a consistent hesitation. It only occurs during the first 15 minutes (or so) after cold startup. I've replaced: plugs, 2 O2 sensors, Mass Air flow, and EVAP Canister.
Am about to try the throttle position sensor.
I purchased a 2004 Toyota Camry Limited Edition in very good condition. The vehicle has 175,000 miles on it but runs just like new. The previous owners must have taken very good care of it because inside and out it looks brand new. It runs great, and the only thing I have had to do so far is replace the a/c relay to get the a/c blowing cold again. This is my question. I decided to test my fuel economy, so i filled the tank with premium gasoline 91 octane.
I reset the trip ODO, and have only driven the car in the city. With the A/C always running, I usually drive anywhere from 4 to 6 miles a day during the week and maybe about 12-15 on the weekend. Well i am down to about an 8th of a tank, the gas light is not on yet but it is pretty low on gas.
According to my trip ODO I have driven 240 miles. Now if this car has a 18.5 gallon tank, that means that with premium gas I am getting about 13 miles a gallon. Even for city driving, that seems just terrible. My 1999 Ford Taurus SE with a DOHC V6 gets 17 and my camry is not even a V6. So I am wanting to know what could be causing this? The car runs perfect, it doesn't miss at all, it sounds great and the oil has been changed and it has great tires.
My mom's 02 Camry is burning oil and I can hear something rattling. The car has 177k miles and my mom bough it new and always cheap out on it. I have looked under the car and do not see any obvious oil leaks. When the car starts after siting overnight you can see a small blue puff come the tail pipe but I have not seen any blue smoke after start up. I have uploaded a video of the rattling here. I had my bother start the car with the hood open but I could not hear any rattle. So I started the car and move it little to start the rattle.
