As many wrote piston slap due to vvt and ignition timing (ignition starts way before piston is at top position causing slap sound). Nothing bad with that. Your engine still runs smootly for 1kr type.
Not the problem with mine. When I put my foot down it does a proper loud chug. That's all I can describe. "Chug chug chug chug chug" when I put my foot down? HELP!
It's the timing chain hitting on the inside of the engine block. I've had an Aygo since 2006 and it has done it ever since it was driven out of the Toyota dealership until the engine warms up. Last year I replaced the engine because it was just drinking oil after reaching 200,000 miles. When I took the old engine apart, you could see the scratching on the inside of the engine block where the chain was hitting the top. As long as you use good quality oil and change it regularly, it won't be an issue. Low quality or the wrong oil will clog up the timing chain tensioner and hinder its performance / stop it working altogether.
@@sebastianborek3591 I'm not saying you're wrong because it's also a common fault with these, but with piston slap, you'd expect to see blue smoke and a drop in the oil level? When the piston hits the side of the cylinder wall you'd end up with scoring and deformation which would allow oil to seep through past the oil seal and burn. Also I know the timing chain tensioner is mechanical and my point was that low or bad quality oil can cause the mechanical parts of tensioner to not work as effectively. I'm not saying it would make the chain loose as such, but that tiny bit of play can cause it to hit the side/top engine block due to there being such little clearance.
This is normal for this vvt engine. It is explained by a former mechanic in a video called: "CityBug "Ticking sound on engine" Explained" Toyota Aygo Peugeot 107 Citroen C1 1KR-FE Tapping Noise"
Hi I have a 2006 Toyota Vitz with the same 1KRFE 1Litre 3 cylinder engine with a little over 55,000 KM. I am getting that sounds too. To me there are portions of the engine that gets restricted from engine oil flow. The sound is more noticeable at low rpm/ when idling. If it requires attention, the sound would be progressively louder at higher rpm or when driving. Also it sound like a pre-donation/ pinging maybe the quality of gas or dirty throttle body. Anyway, I have mine still going strong with all the unwanted noise and vibration
Hello, if it's the 1KR-FE engine, they say it doesn't have hydraulic valve lifters...Regards Any engine with a timing chain needs the right grade/clean/quality oil regularly because if the hydraulic tensioner gets clogged you'll get a loosely fitting chain that will make a rattling sound and may cause severe engine/valve/piston damage.
@@sebastianborek3591 how do think the chain gets up to "tension"? To my knowledge every engine with a timing chain has an hydraulic tensioner and every engine with a timingbelt has a spring operated tensioner. Regards
Back in the day those additives used to be super thick and that's how they quietened things down. But that was pretty thin so I can see why did nothing. The valves are shims and not hydraulic
Give it some time! A couple of hundred miles might do it, but I reckon that it'll be the same hydraulic tappet issue that my AYGO has. Have you tried using a piece of dowel as a stethoscope to narrow down the problem to an individual cylinder? My noise usually disappears for a little while after an oil change, but it soon returns - strangely, it can go away some days, and fortunately it's not apparent when you're on light throttle, so on journeys it's not a real problem.
My aygo was running that badly it looked like it was trying to jump out of the car. Iridium plugs, wynns oil stabilizer and steel seal later, smooth as any engine ive ever heard.
@@johnnyboyle4811 Thank you for your time answering! I used 10w40 3000miles each time but notice that the engine would make a ticking noise, especially in the morning (I do live in the UK) now with the 5w30, I notice that the noise is way less and the engine seems to run smoother. Maybe will get some iridium plugs to see if it helps a little more. Do you think that 5w40 will do the job? thank you for your time Johnny!
@@oceanwave7087 although the engines on these are supposed to be able to run on 0w20 or 5w30 and I've heard of people using 15w40 it's best to stick to a good quality 5w30
Max oil level ( 3.2 liter ) makes my aygo really quiet.. but after 3000 km its noisy.. i give the bi tch 500ml 5w30 from action every 3000 km. And oil change every 10.000km as mister haynes advices
Yo tengo el mismo problema en mi Yaris, ni cambio de cadena, ni bujías, ni limpiar el cuerpo de aceleración, ni pcv, ni maf ni nada, además con la vibración golpetea el escape entre 1500 y 2000 rpm, horroroso
Sincerely for me it sound like a major mechanical fault , pistons ,tappets ,timing chain,you name it, like a very high mileage car probably neglecting regular oil change
This is the timing chain. Even though low mileage I’m wondering if the mileage is 1. Genuine or 2. Has had a diet of poor quality oil. I’ve found that although people claim the 1KRFE is bulletproof, it really is sensitive to correct grades and needs premium oils. It’s known in certain circles that Toyotas own oil is Mobil 1. The problem with cheaper oils is that not only do they increase wear, but they lead to varnishing and organic particulates which clog the timing chain tensioner. The chain may not be that much stressed, but the tensioner takes increased time to reach full pressure, or as can be seen here, perhaps never does along with wear. These are very good, simple engines and considered, sadly - as almost throwaway by many owners … that is until austerity, Covid and the end of affordable sub compact class really hit in. As a result, many of these cars are neglected. They really do rely on top quality oils as the sumps are so tiny and for the more delicate cam gear and softer piston rings for higher MPG. Only use mobil 1 or another premium oil
@@startfromscratch4858Ah, so I was right about it being the chain though, when others were saying piston slap and lifter tick. I wonder what else I might be right about? You would of course know that lifted tick on most cases develops from low quality oil and neglected oil change intervals. So, what do you put the stretched chain / failed tensioner down to? What oil do you use and what history of oil changes / quality did it have?
OK, so I had it fixed. It turns out it was the timing chain. I will upload another video of it fixed when I get a minute.
I don't think you fixed it.Thats no timing chain.
@@sebastianborek3591,, interesting you should say that I will add the other video and let me know what you think
Still waiting on that video
And what?I replaced timing chain as well and sound remained the same.cause it's not chain that's piston slap.
Thank you that'll.
@@sebastianborek3591 Got rid of the car now. It seemed to improve it massively

It's not timing chain it's piston slap as I know from my experience .besides timing tensioner is mechanical not oil tensioner!

That's piston slap.Nothing helps but after some driving when engine is really warm knock disappear.

glad its fixed. just read some of the stupid remarks and on that basis i thought it was low air pressure in the NSR tyre🙄

The 1KR-FE does not use hydraulic lifters. It uses solid bucket lifters directly acted upon by the camshafts.
The Argo don’t have hydraulic tappers there shims a cam out job

Doesn’t this engine need 0W20 engine oil? That’s what it says in the manual book 😮
If you look in the owners manual it says check and adjust tappets at 60,000 miles. It has solid lifters not hydraulic.
Not lifters.piston slap
The same problem in my Aygo mk1. The first thing that came to mind was valve clearence.

it has shimmed buckets in the engine....not hydraulic tappet adjusters!!!
