Camry :: 2002 Toyota With 2AZ-FE Engine - Rattling Noise Coming From Engine

My 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.

Camry :: 2002 Burning Oil And Rattling Noise

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.

Prius (2004-09) :: 2006 - Rattling Noise Coming From The Engine Under Acceleration Only

i have been hearing a rattling noise coming from the engine under acceleration only. It isn't a super consistent rattle, seems to only happen when accelerating from lower speeds. And sometimes you don't hear and other times you do. It's not a bad rattle or knock it's more of a ticking/light rattling sound that is definitely abnormal.

I know my brake accumulator is barking at me and the 3 way coolant valve is going bad as sometimes I get a constant pumping sound. I don't think these have anything to do with it but thought I'd mention it.

Prius (2010-12) :: Slightly Shaking Engine - Rattling Noise On Acceleration?

Slightly shaking engine and rattling noise on acceleration,it happens when the car is hot and especially when the battery level is very low ,I guess is when as more load . If I accelerate and keep it steady at 20mph I can feel a constant vibration but goes away once accelerating more....like if you're driving on a rippled surface ....that is only when engine is on , doesn't happen on electric only.

The noise it sound like a tapping coming from the engine when slowly accelerating from 0 that goes away as soon I give more gas ,is annoying wile in the traffic.? Can the sparks plugs be the problem?they been changed 120k ago.....,I cleaned the egv pipe but problem still there. Like I said is only when the engine is up to running temperature.

Camry :: 2002 - Low Grinding / Rattling Noise In 5th Gear When Cruising On Highway

I've got a 02 Camry with a manual. In 5th gear, cruising on highway, there's a low grinding/ rattling noise. it doesn't do it if you try to accelerate, or if you have no throttle input at all, meaning it only makes the noise when trying to keep one speed, typically around 2000-2500 rpm. If i grab the shifter and apply pressure in any direction, the noise goes away. I've owned the car for 3 years now and its always done it, and hasn't gotten any worse or changed at all. I'm experiencing no performance issues and just chalked this up to gear noise, but recently read someone else was having same issue, and everyone was clamoring on about needing new bearings.

Camry :: 2005 - Rattling Noise When Engine Is On

My 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).

Mazda - Protege :: 2002 Engine Overheating / Rattling Noise Behind The Dash

I drive a 2002 Mazda Protege and it's been great to me until this past weekend. I had a 4.5-5 hour trip ahead of me and Google Maps told me a more direct route (i.e. not using the interstates) would save time. It must have erroneously assumed that the highway comprising basically the entire trip would be speed limit 55-65 the entire way. Instead, I found myself slowing down to stoplights and stop signs in small villages between 15-minute sprints. At some point, the interior heat stops - the air being pulled in from outside is not being warmed at all, no matter what settings I fiddle with. Not long thereafter I notice a rattling noise behind the dash. From inside the car it sounds almost like an animal skittering around in the chassis - irregular, short and clipped. With the hood up and an ear to the engine, it sounds like a piece of plastic fluttering in the wind, but with a faint electric "crackling" quality. Soon thereafter the check-engine light illuminates.

Before long the engine overheats and I pull over to the side of the road. Nothing appears to be leaking, and the crackling sound is the only thing noticable. Being in the middle of nowhere, I jumped back in and proceeded to drive at about 35-40, which was warm on the engine but enough to get me to a small town. At this point I checked the coolant reservoir and it was empty. Bought some from Wal-mart, poured it in, and headed out. Things looked fine at first since the engine had sat cold while I was running errands, but pretty soon it was overheating again at speeds as low as 30mph. After getting it towed to my destination, I took it to a garage the next morning. They couldn't find anything wrong with it, and indeed when I drove it back to the hotel that morning the engine behaved normally, the check-engine light was off, and the interior heating was functioning properly.

The next morning, when it was time to depart (but again after an entire night of sitting in the cold), a 20 minute drive to breakfast was smooth as before. Thinking that the mechanic had either waved a magic wand or I'd gotten extremely lucky, I hit the highway and did 65 for a good 20 minutes until the engine began to overheat again. Slowing down to 45 bought a few more minutes to find an exit, but eventually I had to pull over. Popping the hood, I notice the coolant in the reservoir is bubbling to the top! Thinking the mechanic might have added more and overfilled it, I cursed him in absentia. After a good fifteen minutes of cooling off, the coolant settled and in fact drained the reservoir entirely; I refilled it to the line and, again being in rural snowtopia with few options, decided to hit the road again. Not wanting to tempt fate, I stuck to 55mph and the car ran fine for an hour and a half (with the interior heat blasting, per a friend's advice). I stopped once to check the coolant and all was as it should have been - just below the line I'd filled it to earlier. Closer to a city, I decided to experiment again and took the speed up to 60mph.

This was great for 20-30 minutes but eventually the engine began overheating ever-so-slowly and I had to pull over, let it cool off, and replace another full reservoir's worth of coolant that had disappeared before I kept going. I drove the rest of the way home going no faster than 55mph and stopping on occasion to check the coolant. It overheated once even while doing 55mph, but a 15 minute break + coolant refill bought it the rest of the trip. In summary: Although not 100% correlated, going faster than 55mph seems to trigger the engine overheating, at which point the rattling noise appears and the coolant begins to bubble its way back up the reservoir (like it's boiling?!). I'm not sure how the coolant is disappearing because I'm unable to find any leak, nor is there any extra exhaust that would suggest it's burning.

Toyota - Corolla :: 2002 - Engine Noise On Acceleration - A/C High Pitch Noise

I have a 2002 Corolla with about 180,000 miles that has been well maintained, but I know very little about cars.

Over the past months, I've noticed the engine noise on acceleration sounds a bit louder than I would expect it to, and it seems to be getting louder over time. It's slow changing, so I'm a little unsure. And occasionally I wonder if I don't hear a sound that shouldn't be there, though I couldn't describe it yet. Mechanic said the acceleration noise is normal at start-up for older cars until they get warm, but this happens even after I've been driving a while. Worth the $100 for an engine checkup?

Also, the A/C doesn't seem to be the strongest and has a high pitch noise when I run it. Normal?

Camry :: 2007 - Engine Rattling Noise Pretty Consistent

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?

Camry :: 2003 / 4 Cyl - Slight Rattling Noise When Start The Engine

I 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.

Camry :: 2007 - Rattling Noise Mostly When Engine Is Cold Started

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.

Camry :: 2006 - Random Rattling Noise Under Hood Near Engine On Passenger Side

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.

Ford - Explorer :: 2003 - Rattling Right After Engine Is Started - Slow Acceleration As If Engine Has No Power

2003 Ford Sport Trac with 4.0L SOHC engine

I started having this problem after I decided to do a tune up because of another minor unrelated problem (start up taking 2+ cranks sometimes and fine when gas is full... I'm going to replace the fuel pump for that but not until i resolve the more pressing issue)

Before the problem I had spark plugs and wires (all but #3) replaced by my dad and he also put in some Fuel Cleaner into the gas tank. He took it to a local mechanic and had the mechanic replace the #3 spark and wire and check the others and also replace the fuel filter.

After that my car was taken to jiffy lube where engine oil was changed... as well something else but I dont know what because no one is able to tell me.... my dad had one of his employees take it and the employee took it upon himself to get other things done but he doesn't know what.

And then when I got my car back after the weekend is when this issue started.

First I noticed a rattling (like a plastic is caught on a fan blade and it is hitting something as it goes round and round) right after engine is started. And on the roads, when I try to accelerate, it will accelerate- but very slowly as if my engine had no power.

When I floor my gas pedal, the car will continue to drive at a constant speed and I can start to hear a really fast rattling which I am not sure if it is the same thing making the rattling sound I hear at start up.

I've gotten the following codes : 300, 301, 303, 316

I have since then had my spark plugs rechecked, wires for #1, 2, 3 and 4 replaced with another brand. There was no long term change but I have noticed that every time messed with the wires (when spark plugs were changed, when wires were changed and when sparks were checked... etc) for about 3 drives right after it the car feels more powerful and smooth and then it will go back to driving like crap.

I have also changed the CKP sensor (advice of the Auto Zone) and there has been no change.
I have also replaced the coil pack this weekend and no change.
I have bought the more expensive wires but didn't change them since 2nd set for 1, 2, 3 and 4 has not made changes.

Currently: Only thing I have more noticed is that the car when first driven, feels okay at start up. I can accelerate from 0 to 30 with decent power and time and as long as i dont floor the gas and only lightly depress the gas the car will continue to accelerate with decent power and speed.

However, anytime the engine is strained (like going up a hill) I loose speed. and AFTER any time the engine is strained, i will no longer be able to accelerate with decent power and time.

The car at this point feels like it it trying, almost sounds and feels gritty if that makes any sense, and if i try to at least keep speed, the engine sounds change but no increase in speed. At this point I usually just try tapping lightly on the gas and it will eventually get upto 30mph and of course more effort to go beyond and continually increase the speed.

It takes me a good few minutes for me to go from 0 to 35 and another few minutes to get upto 45. (Now everyone drives around me after a complete stop because I cannot even get to 20 right away like most normal working cars.)

I really would hate to replace one part at a time to play guess and check but I also don't know any true mechanics in the area that can really drive, listen and look and determine what exactly is going on without playing guess and check with every little and big parts that are involved. I have seen some people replace the intake manifold, O2 sensors, CKP/CAM sensors, cylinders...

Prius (2004-09) :: Metallic Rattling Noise On Acceleration

While driving through a tunnel today I noticed a metallic rattling noise upon acceleration. It goes away immediately when I let me foot off the gas and when I park the car and rev the engine the sound does not occur.

A few days ago, I had to rapidly accelerate and it felt as though I lost power for a split second. I am not sure if these are related, but I am hoping its not some sort of transmission issue (unless that is covered under the hybrid warranty. What was the diagnosis?

Ford 7.3L Power Stroke (1999-2003) :: 2002 - Blowing White Smoke - Low Power - Rattling Noise From Engine - Broke Down?

Moving my worldly goods from California to Oklahoma in a rented 26' box truck with my wife following in our '02 F350 loaded to the gills with my lathe, mill, air compressor, weld and assorted machinery. Just west of Deming NM it started to blow lots of white smoke and down on power. Some rattling noises from the engine when throttled up & won't reach 3000RPM.

Had it towed to an impound yard for storage. Plan on sending a flat bed to pick it up when we get to Tulsa.

Any experience with a tilt back trailer capable of loading & transporting this truck that weighs around 17,000 pounds? My plan is to continue on to Tulsa & make arrangements from there.

Prius (2010-12) :: 2013 - Squealing / Rattling Noise During Acceleration

2013 Prius 3 making a squealing or rattling noise when accelerating after car is warmed up. It only does it when the car is up to temperature and when you accelerate slightly harder, like going up a hill or something. It sounds like a pulley or something squealing. It has been to the dealer and of course they couldn't duplicate the noise or see anything wrong. Not to sound funny, but it actually sounds like a hamster running on a wheel. It is very annoying. It is not a constant noise, it only happens under load. It gets louder when the ac is on as well. If you let off the accelerator when it starts the noise goes away. I don't know of it matters but our car has the forged 17" wheels on it from the factory, and the car has 8600 miles on it.
