Here's the thing, without an actual demonstration of the VVT rattling sound, this explanation is only about 60% helpful.
Cry
@@mikem5475 I have no idea what that means.
@@theylied1776 "cry" as in "go cry about it".
But I don't what they're on about, you are correct
@@mr0o Oh my god? Did you use some kind of translation app or program for this? I have almost no idea what you're trying to say here.
All videos that speak on a sound aren’t showing an example
I was expecting to hear the actual sound. Not have someone talk about what it sounds like. Lmao 🤣
My 2009 2azfe with 247k had this issue. After replacing the intake cam phaser, which did not fix my issue, I drppoed the oil pan to inspect the oil pump pickup screen. It was severly clogged with crap. Old RTV sealer and other small junk. About 70% clogged. Cleaned it and reassembled. Waited over night to test with a cold start. Its fixed. have pics of the crap if anyone wants to see it. I think someone else was in there before me, but did not know what they were doing.
Hope this helps.
I've seen you post this on other videos. I will speak for the entire car community and say we appreciate your diligence and dedication to make sure people can see the details of your experience. I'll be putting a borescope in my oil pan drain to check it out thanks to your story
@@Quinn05how is it going?
It is a good thing you did not record the noise. Then I could have figured out what you were talking about. Next video, discuss dirty oil, but never show it.
Oil changes don't prevent vvt rattle on cold starts... Its just a faulty design. The pin usually has a spring that wears out over time no matter how good your maintenance is.
Edit: Frequent oil changes can prolong the problem until later. But it will happen sooner or later.
Whats the fix
@@feraskhodary5497 You need to replace the valve timing gears at the top of the timing chain.
You are right,I recently start hearing this rattle noise on my Peugeot 207 1.6 hdi , the next day I changed timing belt but the sound is still there , I always was changing the oil before was due because i service the car myself so definitely the problem is not because of the oil change but is because of a lot of miles 😅
Al cambiar esa pieza, es necesario cambiar el kit de cadena de tiempo???
my toyota camry 2010 hybrid have same problem,this rattle sound lasts about 1-2 sec,is it dangerous or could it damage something?
Great vlog!
not really
Now I'm down to either the VVT actuator or a timing chain tensioner on my 2015 MB C300 4matic turbo w205 (longitudinal) with 59000 miles. The noise is loud, rattles, like an old set of Chevy lifters gone bad, but goes away. any guesses? Funny, the motor has no codes and car gets 38 MPG on highway.
I have a 08 toyota Highlander when I start my car in the morning it start off good it doesn't make a sound at all but it does after I turn the engine for a while and when I turn it on it rattle for a second then goes away never comes back until I turn the car oof again and it drive hella smooth do I have to worry about this issue?
So is it a real problem like should I get it fix?
My 2014 Honda CRV rattles on start up I use the proper oil and it only has 9 thousand miles on it. I tap the starter 2 or 3 times then no rattle.
I uploaded a video on my account of My car making nasty noise and shaking when starting the car, do You think it might be the VVT ?
Thanks for your video, I wanted to know if something bad would happen if I did not change the actuator? Thanks
If the actuator pin shears off, it can cause the timing chain to break and destroy the rest of your engine.
@@rickuyeda4818 evenning Mr Rick I would like to know my E87116i when I plug in my intake and exhaust connection the car engen shake terribly,please why that help and now I drive the car without those connections.
Mines only on start up cold when its warm doesnt do it coming from top. Of engine prob due to not getting oil changed
What car?
just give some time to the car opening the switch a minute or two or three before start the engine, why the key has some steps before start the engine? Cold weather affects everything
Same in my corolla the mechanic told me that its safe to drive nothing to worry about
Yeah I'm just getting this nose 9n my Toyota Corolla 2005 rattle
@@wolfseek Here are 2 solutions. Add seafoam to the crankcase 2-4 ounces or switch to 0w 30 oil. I have a 2007 Corolla that had the same problem at cold start up. The seafoam will clean and help the oil flow easily through the gear and the 0w- 30 oil will do the same. I no longer have the rattle. Always change your oil and oem filter, i do every 4k miles. i am running Mobil 1 FS 0W-30
So, the symptoms are: timing chain hits the guide on cold start up. there are could be few reasons: 1- (like you said VVT Sprocket), 2- VVT Solenoid malfunction and/or Oil Filter Screen clogged (basically, not enough or no oil going to VVT Sprocket, not to mention electrical issue with the solenoid), 3 - timing chain tensioner is worn. In the book, its even offering to take a look of crankshaft thrust bearing (hmmm, interesting - thinking of noise comes from the bottom of the engine - on cold startup as well)
Whose 57 Plymouth is on the lift back there?!
There's a kit on the market which is a reserved pressurized oil tank to feed the actuator before engine start. Another trick is to crank the engine but turn it off before starting. Doing this a few times will pump oil to the actuators.
Won’t that wear the starter much much faster though, and eventually break it?
Foorget the starter, that will wear your engine out.
So what's the kit? You don't even link it
Link for the kit?
Hello there, first you are amazing , May I ask you I have same this problem ,if I don't fix it ,is any risk about it , I mean The noisy that going bigger? Thanks
Same question here.
To be honest its not very loud. Most of the noise comes from the actuator and fault, but the cause is a partially blocked oil pickup screen. So even after installing new vvts , check oil pick up screen. Otherwuse this may happen again.
Mine does it and it will kill the engine sometimes and then start right up and run perfectly. I’m scared
I let my car idle in park for 2 minutes before shutting it down. When I go to start it up again there is no rattle. Even if the car sits over night. It's been working for me
I will have to try that
@@JeffGary9 try it dude ! Let me know if it works for you
Yah I noticed if I sit there and let the car idle for a while it wont rattle the next morning but if I shut it off immediately after parking it, it will rattle the next day.
i will try that too..
yo guys just turn the key in the engine for the electric to work wait 10 sec take out the key wait 10 sec put the key back put the electric on wait 10 sec then start your engine and ratling sounds gone !
Nice explanation👍how long can engine last without changing actuator. My wife’s crv been doing that for awhile. The Honda dealer never mention it.
It’s not really that important tbh.
I have a honda CRV that is making the noise as well. Has your wife gotten it fixed?
My corrola has been doing that for 5 years I just fill her more than usual with oil so the pressure can build up faster
If you have a 2014 Honda Accord Sport, double check because changing the actuator at the shop is expensive! Your problem is the timing chain tensioner. The part is around $50!
was hoping to to see an hear a clip of the noise 😒
In my experience, it could either be the solenoid or the actuator. I would replace the solenoid first and see if that fixes the issue. I replaced the solenoid and the sound only happens for like a split second. But before, it went on until I drove past 20mph and even then sometimes it wouldn’t stop making the noise
My car makes the noise Constantly i don’t even wanna drive it
@@justinmatthews9465 like my comment says, try the solenoid.
i’ve replaced the solenoid and the connection to the solenoid, and still rattles and feels low on power, just can’t figure it out, check engine light went away but the problems didn’t
@@bandsawjones actuator or maybe OCV screen is clogged
This isn’t helpful at all unless you give us an example of what the rattling sounds like ….
Thank you i know right
😂
Gee, that tell us much. This would be 100x better if you actually gave us an example of the noise.
Well at least show the part of what went wrong.
Is the rattle coming from the chain hitting the sides?
It’s coming from the cam gear itself
What's kind of the parts we have to repair. Please let me know. Thanks.
He.said actuator i guess.
So the cause is low oil pressure at start up and the best way to solve is to not replace the oil pump but to replace the actuator ?? Could've at least shown the bad new part installed by the factory in all engines that needs replacing with another new bad part. What is the real solution ?
Can you show what is the noise? Because there are lot of videos where there is similar noise but It was starter or engine mount
Engine will rattle like a deisel engine for maybe one second when starting after engine has been off for a while & oil has drained down into the oil pan. It will quit after that one ( or 1/2 ) second unless really cold it might be 2 seconds until oil gets back up to solenoid/actuator.
@@tubetime39 is it normal or needs fix , mine does for 1-3 secs ?
My 4cyl Rav4 has been making this noise since 140k miles ish. It now has 159k. Should I really be concerned and get it fixed? I heard of people with the same engine that did not bother fixing it and easily got 250-300k miles out of the car. The noise lasts for a second. One and half at the most. Is there anything I can do before starting the engine to prevent this?
Nope. Just drive it as is until the motor dies. Who knows, it may actually die at 400,000 miles. Of course, continue to change oil and filter every 3k miles.
With your engine the noise is harmless. With the Toyota 2GR FE 3.5 6cyl. The noise is a death warning. Don't worry about it. There is a guy on RUclips I think his channel is "speedvar"...he has a video and goes into depth on this precise issue.
@@TheBenjammin Thank you ! I was really concerned but since writing the original comment, I naturally drove a lot and the car now has 227k miles. Noise remains, lasts for about a second or two then goes away. High mileage oil with stabilizer additive helps a bunch, sometimes it doesn’t even make the noise.
Not only toyotas vvt but Mazdas skyactive engine does the exact same thing at cold start...
Cranking the engine for a few more seconds before starting solves this problem
same here
What do mean by cranking?
I have changed my oil every 3000 miles since I've had my car. The previous owner who knows. Now my car is making the noise after cold start.
How about a sample sound????????????
This is the sound from my Acura TSX:
ruclips.net/video/T9IkqM_kud8/видео.html
I am currently experiencing this. What is the actuator and where is it located?
The actuator is buried inside the engine camshaft. It would cost thousands in labour to fix in the time it takes... Not worth fixing. Just deal with the noise.
You can’t put a new pin and fix the problem
Remove 16 Oz of oil from your motor and add 16 Oz of transmission fluid. With time it will break down and clean out the carbon build up and rattle will go away.
another video on the surface
I replace my oil every 5000 miles since new and my Toyota makes this noise
cap I change mine every 14,000 miles ( though I use a high quality oil) and it still make noise. It made noise when I bought it ( though the dealership hid it from me by insisting to start the veh & bring it to me each of the two times so I wouldn't notice it. I was at dealership with buddies truck for service both times & had plenty of time to go get the Honda accord each time.
So bought at 111,000 miles, with exsisting problem &
@@tubetime39 I also use high quality oil I’m just making a point he says to change your oil regularly. This is just an issue with these engines. I have no doubt this RAV4 will last a long time though
Would have been a ton more helpful if you actually had the sound of the issue... -1
Like they should already know the wngine will starve the 1st few seconda of start up which will eventually lead to failure over the yrs. if yours not doi g this yet it will
Mine started this at 23,000 mile. Why would I spend money to replace with same damn design and have it happen all over again ?
Yea mine does it also for 3 years now only cold starts,but the replacement part is still faulty so you would be just wasting money to not hear it again for a year or less...no point in replacing
I’ve changed my actuator , Timing chain, tensioner and guides and I still get the cold start rattle! So isn’t correct
Have you tried replacing the solenoids?
I’ve got the same noise but haven’t done anything about it- mostly because they said it was a 3400 job. I’ve heard the solenoids could be the issue so if you do change them and it fixes the rattle please update us :)
The rattle has now gone , the first start up after the vtc actuator , chain , guides and tensioner fitted it had a slight rattle on first start up but now ( 2 weeks later ) I’ve not heard the noise so I think it’s been cured. The pin inside the old actuator must have been damaged
Mike2491FEM one more thing, did you change them yourself or pay someone else to do the work. What did you pay or what would you charge. Also, do you have a link to the parts for the job?
JRESHOW I had a Honda specialist do it for me , he builds track cars and general maintenance on Honda vtec engines. It was on a k20a2 engine and all the parts were from Tegiwa.
"sometimes the actuator can be damaged"
No, all the time. This is basically a wearable part that WILL fail on your car eventually.
so why create such a design? older cars without all the vvt systems were better. 😑
You're too too brief Sir
so prime your oil pump before you fully start the car. problem solved
How would you prime the oil pump before starting th he car? Honest question
Maybe prime ribs 😆 I'm lost.
@@islamicwaylive you can not prime the engine before starting the car, the oil pump is driven through a belt for the engine
WHAT SOUND WHY YOU DIDN'T SHOW IT....WHY KEEP TALKING WITHOUT SHARE HOW THE SOUND LOOKS LIKE??? IMPROVE IT.
Useless.
