Prius (2004-09) :: 2006 - Rattling Noise When Combustion Engine Is Engaged
Dec 11, 2012
My '06 Prius just started making this noise. the check engine light is NOT on. I haven't really heard this noise before in my recollection. I just got an oil change 3 days ago and when I got the oil change there was no indication from the dealership that there were any issues. The engine only makes this noise when the combustion engine is engaged. I can't see any wobbling on the belt drives or and loose parts in the engine. The spin appears to be coming from the engine block or around the pullys for the belt. My first thought is that it could be dirty gas because I first heard this sound after filling up. I am 300 miles from home and have to drive home today.

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.

Our 04 Prius makes a really scary metallic noise at the top of the engine when it is engaged. All maintenance has been performed within 100 miles of the warning light. We are the original owners and the car has 160k miles. No pulleys are touching their surroundings. Make no mistake, this a LOUD noise that has been growing with time. No warning lights,,,oil level is fine,,,and no metal visible on the dipstick. Sound is originating at the top of the engine and is not a "knock". It is more of a metal on metal type of noise.

RX 400H 2006 model. After 130k km, the car suddenly stopped with check hybrid warnings. The one and only lexus dealer in Greece replaced the hybrid unit due to failure of the power module. ( the car was on recall but they have never contacted me). After the replacement there was a rattle sound coming from the combustion engine when it was running on the morning for 3-5 min.The new inspection of the dealer showed a crack on the head gasket of the 4th cylinder.( I have post it here under a different username) .
The options that I was given was either to have the engine replaced with a used one or to fix the old engine. The cost of fixing was triple of finding an engine. So I purchased a used one (via ebay!) , it was from a car issued in the United Sates. The one and only dealer refused to put it on my vechicle because it was not going to fit and work due to different electrical wiring . So I found a mechanic who managed to put on the us engine easily and with no issues except from a yellow light that goes on seconds after staring the ignition key.On the diagnostic tool shows a warning about ABS system although the brakes are ok and ABS works fine. The car is running after engine replacement for 25k km with no problems. I attach a photo of it.

I currently own an mk6 gti with a manual trans... as of late I've been noticing a rattling noise when the clutch pedal is not engaged.. once engaged the rattling stops completely .. it seems to be getting louder and louder .. I am worried this could eventually turn into something worse than just a rattling noise .. i had a friend mention it could be the "throwout bearing" ..

My manual 2004 Ford Ranger XLT (4.0L) has been Buzzing/Rattling. (VIDEO LINK BELOW) She has 112k miles on her. Owned 1 month, no issues when I bought from my paps. Its my 1st manual so may have been a little hard on clutch 1st few days. Noise started abruptly 1 week ago when I engaged clutch to shift to 3rd. Its gotten worse over the few days and happens even when in gear. Its much more prominent from outside passenger window. Don't notice for 1st couple mins of driving & is intermittent but often. Noticeably louder when foot is taken off gas in motion. Does not make noise when idling. Generally only above 1500 RPM . Not coming from the back half so I don't think its the exhaust/heatshield
Heres the sound......

This must have been asked before but I couldn't find any thread about it. Have a 2006 F350 that makes a rattling sound when engaged in front wheel drive. Sounds a bit like a loose ball from a ball bearing (or a small stone) rolling around. What might be causing this?

Engine oil has been changed and spark plugs changed. The engine is still making rattling/clicking noise. I checked with a mechanic and he indicated that engine needs to be repaired. Didn't say exactly what needs to be done and stated it would cost about $2200 for parts and labor. Why the engine keeps rattling and making the noise? Oh, before plugs were changed, the engine was shutting off at times when in idle mode.

Recently my engine started making a rattling noise. It does not matter if the engine is warm or cold. In either condition it produces the same noise. The noise can be best heard at the back of the engine. My car is a Sonata 2.4 GLS from 2006 and has roughly 110000km on the odometer.

Tomorrow I'm dropping the car off to the dealer in hopes that they can find it.

so with the weather turning cooler i have noticed a new noise. i am at 34,000 miles and run synthetic oil ever 4-5k miles.
I hear a rattling/knocking noise when you start engine, not right away, but like after 15 seconds and it lasts about 30 seconds then seems to go away and is quiet again.
Almost sounds like a lifter is tapping due to not getting oil.
I changed the accessory belts a while ago and it did not first make this noise right after but maybe a few days after which coincided going from 80 degree weather down to 40 degree weather.
Could it be an accessory belt being too tight? If so, why wouldn't it make it on startup? I can see it going away as rubber expands as the warms but I would expect it to make the noise from starting till then. Not 15 seconds into running.

Recently when I first start my car in the morning, there is a rattling noise, which sounds like it's coming from the driver's side of the engine bay, or possibly just under the drivers side door. It only lasts for a couple of minutes. It will increase I accelerate, and then decrease as soon as I lift off the gas. After a couple minutes, the rattling goes away, and everything is right in the world. Today I drove it around the block and parked while it was still rattling away. When I put it in park the rattling went away. I put it back in drive and it came back. Then as usual it finally went away whether in drive or park. I'm completely stumped on this one. It's an '08 2.4l GLS and has 138,000 miles.

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.

I have a high milage (210K) '07 2.4L which has a slight engine rattling noise at idle RPM at cold and operating temps, in gear or park. It is a fairly constant noise at idle but does vary a little. Otherwise, engine/tranny operate beautifully with no obvious problems.
I am concerned this could be a timing chain/tensioner related issue although I also wonder if it may be some other component. I have not been able to determine the source or location of the sound.

At first it was leaking coolant very slowly,then making the rattling engine noise at low rpm then a part flew off while on the highway gushing out oil. Time for a new used engine. Planning on diy if all else fails off the junker. 230,000 miles on odo.

CEL came on in July at 165K miles, though there weren't any noticeable issues with performance. I took it to the dealership and they found P0300 and P0304 misfire codes. They replaced the spark plugs, and everything seemed fine for over a month.
They said I still had original spark plugs, which I refused. causes, replace/repair engine? I had 100K service at this dealership, which included "Replace regular spark plugs". I found out later from them that because the Prius doesn't have "regular" spark plugs, they didn't replace them during this service and didn't bother to tell me.

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?

Recently, my 04 accent (97,000 miles on engine and auto trans) has started to develop a rattling or Clanking noise coming from the engine at low RPM's. I flushed the engine and changed the oil and oil filter, thinking it could be due to oil clogging the HLA, But this was a no go. The engine is still making the noise, and I think it is starting to get worse.
The noise only happens when the car is idling at low RPM's. As soon as I rev the engine past 1000-1500 RPM's, the noise stops. The noise is worse when idling in gear, either reverse or drive, however as soon as you accelerate past 1000-1500 RPM, the noise goes away, until you decelerate to low RPM again. I'll try to take a video of it and post a link to it on here tomorrow.

My 2006 Prius with 243,000 miles has an engine rattle under stress. When accelerating quickly or climbing a really steep hill it will rattle. I think it sounds like a chain. If I ease of the gas pedal, the rattle stops. Is this normal? Does this sound like a timing chain issue?

My wife calls me yesterday and said she could hear a rattling noise from the engine area, but no other issues presented themselves. Later, I checked the engine compartment for the noise with the engine on and found that the noise was coming from the area of the engine water pump/idler pulley but i couldn't really narrow it much closer. The noise honestly sounds like bearings about to go out. I did see that behind the water pump pulley there was a small buildup of corrosion on the water pump, but no apparent leaks or wetness. The car has the original water pump and idler pulley with 140k. I plan on replacing the water pump, idler pulley and thermostat in the morning. Or is this overkill? I don't want to lose the engine nor do I want my wife to get stranded anywhere.

I have a 2004 explorer that has a clicking/rattling noise in the front of the engine. What i found is that the bottom pulley has a sleeve or ring inside of that pulley that is just floating loosely back and forth. What this is or what it is supposed to be ??? If it is a bad part, what is the best way to fix it ?
