me too.
anyone can help us?

 

Just acquired my uncles 2010 Camry noticed the same thing called a dealer was told it is ok. I put in Mobil 1 small rattle for a second or less on cold start . Mine only 43000 miles but in service date so sorry not covered. Have to go what I was told..

 

If any of you experiencing this issue are not running a Toyota filter and the recommended 5/20 or 0/20 oil, I'd start there. You'd be amazed at the weirdness a non-OEM filter will cause.

 

I have a 2010 I4 with the start-up rattle. I have only used Toyota OEM filters and Toyota 0w-20 oil.

A few years ago, I had them "fix" it, but it came back within a few weeks.

I have just ignored it, 50k miles on it currently.

 

Hmm, I figured that's just "how they are". When I worked rental cars, all my Camrys were like that. Altimas, too.

 

Actually I bought Camry 2010 US and I am in kurdistan /iraq now.
so I changed the oil to 5/30 and 92 k miles on camry Dashboard currently .
I have mentioned issue and oil decreased daily i don't know why ?
I Appreciate if you help me .
:help::help::help::help:

 

Does your issue pertain to a 4cyl with engine rattle/knock on start up? Or just oil consumption?

 

I heard from the mechanician person said rattle noise heard on startup because of the digital's engine?
it is right !!!!!!!
anyone experienced with digital engaine and with this issue ,please?

 

thank you Gyota
both of them , rattle/knock on start up and oil consumption without any blue smoke.

 

Have you taken it to the dealer? Mine's going in tomorrow afternoon to hopefully apply this TSB. Wish me luck!

My last TSB application didn't go as smooth as planned. I had to convince the dealership it applied to my car. They were clueless. But I'm going back home and taking it to the dealer I purchased it from this time.

 

best luck for you gyota.
i hope your car's problem fix successfully ?
I didn't bring it to dealer and I Am try to use the cleaner because I think my engine very dirty after that i will bring it to dealer.

Just i can't understand it is mecanicien engine problem or not. why it is not repeated while the engine hot?
and let me explain during start the engine i heard rattle noise and I shut off the engine after one minute next I didn't hear anything when i start engine again ?:crying::crying::crying::crying::crying::crying::crying:

 

This issue is pretty much the annoying trademark of Toyota engine, new or old, and has been a problem for many many years now throughout various Toyota models. There is a ton of threads on here related to this problem.


The problem is oil cannot get up to the VVT cam gears quick enough during a cold start. If you watch the video on youtube on how VVT works you will understand why it will rattle if oil cannot get up there in time.


The rattle does not usually repeat itself after the engine is warm or starting it again right after because oil has already reached the part. Many people have found using 0w-20 synthetic oil helps with the rattle but does not eliminate it. At least with synthetic oil you know there is a small layer of protection while waiting for the oil to go up.


That being said many of us just live with it. Many who have had the TSB procedure done after a while it just came back. All of the Toyotas in my household have the rattle and oil consumption but we just ignore it and keep up regular maintenance.


Also, yes, the 4-cyl camry is also known for oil consumption I guess another trademark of Toyota.

 

Well, the 4 cyl 2.4L on the 2007-2009 is known for oil consumption. There is a service bulletin that just came out for this and Toyota will repair and/or reimburse you if you have already had it repaired. Must be 10 years old or less, and 150k miles or less. Car needs to have the consumption measured first to determine if excessive. See other thread. But my 2010 with the 4cy 2.5L does not consume oil.

 

Well mine got "fixed" this morning. I didn't think the dealer would be able to hear the noise due to me driving it yesterday (warming up the engine) and having them actually check it yesterday. But they called and said they heard it and would fix it this morning. So even if it comes back or persists, I now have some new parts in my motor which makes me feel better.

I agree that this is just a Toyota thing that we should get used to though. I remember going out looking at minivans with my parents a long time ago and we thought it was so weird that a brand new Toyota Previa (right?) van had a ticking sound when it was running. This was like 15 years ago. I actually really like the way those vans look.

 

Thank you smancer
let's wait to the result from gyota.:chug:

any update from you gyota?
rattle noise fixed or not ?0:thewave::thewave:

 

I thought it had cleared until I actually started driving this morning.... New parts at least. It wasn't doing it while idling after starting it up though. It's an improvement. I'll listen again tomorrow morning to make sure I'm not confusing it with a typical noisy Toyota motor.

 

I have camry 4 CYL Dual vvt-i engine and it has rattle noise during cold start for one second .I changed the oil to Valvoline SynPower Full Synthetic Motor Oil 0W20 but noise not fixed ,so TBS can solve the problem permanent or not?
engine flush by cleaner can help me ?
it is possible rattle noise came out because Of OCV issue or dirty OCV filter dirty or screen filter?
mileage of my camry is 93 KMile ,please share you experience and advice me how to solve it by the best way.


i read so many thread but i didn't get the real experiment with this issue and the right way to solved it .

this is the video in my camry 2010 rattle noise during first startup.

can you do a video without applying gas/throttle?

 

You can drive just 65-70 mph not 100 like my neighbor

You have to get it up to 100 every now and then for a little fun. Every out of town trip I take I do this. I'm just very careful where and when I do it. I'm surprised how easily it goes from 70 to 90-100 after how slow it is to get up to speed. I know imports are always like this though. My 97' Maxima was slow getting up to 60 but after that it was very quick. 100 in no time at all.

 

My rattle/knock has gone away for the most part as far as I can tell. And even if you get the TSB applied and it doesn't take care of the problem, at least you know you've got some new parts in your motor.

 

thank you gyota for your care
sorry kak gyota
actually I Am not mechanician person(I AM comunication engineering ) and i don't know how to do it ?
I purchased my car (camry 2010 4 CYL dual vvt-i,mileage 92 Kmile(USA model)) and I think nothing applied to the engine, it is original as is it ,no service applied till now.
now I have the rattle noise and oil consumption and I used 5w-20 valvoline oil ?
next step I will provide new video and oil consumption test to more clarifying the problem.
i want to know what is the exact issue and i can solve it by change oil type or cleaner, if not i will try sell it or repair it .

I don't understand why there is no any blue smock if engine counsum oil and why rattle noise heard just when the engine cold

 

Piston rings get stuck n ruin the cylinder. 1 litter per 1000 k is normal burn. Try lucas oil

 

engine rattle noise startup

I want to test the oil consumption :
Oil level:

2.Trip B reset :
http://www.directupload.net/file/d/3865/al4aujwn_jpg.htm
I will drive the car until I noticed the decrement in oil level after that we will see how many oil consump per drive mile ?

 

No problem it just sounded like you were giving it gas. It's a shame you're having such a bad oil consumption issue on such a new car.Without me going back and reading everything, you've had it checked/checked yourself for leaks right? It shouldn't be leaking but you never know. Changing your PCV valve may help with something? It could be dirty/clogged with 93k on it. They are cheap from the dealer... around $8 I think.

I've been using Mobil 1 0w-20 since I purchased mine a year and a half ago fyi.

That is pretty "rattley" though. I'm not all that mechanically inclined myself but I don't feel like it should be doing that no matter what oil you use. And it's louder than your typical Toyota tapping noise. Have you gotten a Toyota dealer's opinion on this?

 

could you show me the location of PCV valve by picture?
I was bring it to mechanical person said it is nothing drive it until the sound continuously louder after that change came shift and another one said it is heard during startup because egine dirty .
I used the cleaner to flush the engine but not gone .
I will bring it to technician to check it by PC ?
I think my engie very dirty. may be engine filters leakage.
