- This 1 litre ecoflex engine fitted to a 2010 vauxhall corse was not the original engine in the vehicle. it was a replacement engine but it came with worn out swirl flaps in the inlet manifold which sounded as if the engine was rattling..
Well done Alan, Like you said it sounds like the engine is shot.
I wonder how many owners have been told that they need a new engine by unscrupulous garages.
Only for them to fit or bodge the swirl flaps.
Keep up the good work, I now know that if I hear someone mention that their ecoflex engine is shot, I can tell them about the swirl flaps and the quick way to tell if it is them at fault by removing the vacuum pipe.
😁
Lovve u man
You got to be very careful when your flaps start playing up 😂
Your a very clever man Alan 👌
🤣lol
Never knew that always put it down to timing chain knackered!! Thanks Alan! I’ll check that next time I get one in
Hi Alan thank god you put this on you tube i had a 1ltr on a 14plate corsa you have proved me right this thing is ratting like a .... thanks mate for that Pete
cheers pete
You are a very thorough mechanic. Pity every car owner cannot use your services. My 2L Duratec is still quiet at 79,000 miles anyway. But I will listen.
my 2ltr duratec is at 178,000 miles and has no issues at all.
thanks finglesham
Had the same problem with my mk3 mondeo but put a small bolt in the pipe ! Daughter had the same problem with her corsa so plugged that one !!! No other flaps are flapping thank god 👍👍👍👍👍👍 great content Alan!!!!
😁
How are those 2 motors going now mate? Any difference in fuel consumption or other problems? Did they pass emissions test on the MOT ok?
@@wmsstuff271 both passed emissions and mk3 now sold ,Ive now got a mk4 scti 2 ltr mondeo petrol turbo !!!
@@coopers4491 Cool. I just bought a mk3 with 30k miles on it. Gonna try deactivating these flaps on it. The noise is quiet but still annoying
@@wmsstuff271have you done it yet and have you noticed any fuel dropping . As my Corsa been doing it a while and is very loud now
I cant thank you enough, I took my car with this very problem today to a mechanic he spoke as if I should scrap it. My beautiful 2010 corsa ecoflex was in tears, until I went down a d pulled that pipe off and yipee the noise went, I will get a new inlet manifold fitted asap though.
Swirl flaps are normally for duel length manifolds. Long inlet runners are good for torque, but not so much for rpm. So the ecu adjusts the flaps to create long and short lengths to suit rpm, load.
Yeah that's correct. The dual length runners in the inlet manifold enhance torque. Incidentally Mitsubishi had this in their 3.5l V6 petrol and the butterfly valves were brass with brass screws. Over time they come loose and you end up with brass screws going into the cylinders. Brass is incompressible.....
For ensuring no wallet shocks, we removed the valves....
Other problem with the Vauxhall as shown in the video is that it'll draw in false air through the worn shafts/holes and make the car run lean, maybe even sending some horrible O2 codes and getting on a wild goose chase.
If it was my car I'd disconnect the mechanical link, seal up the manifold holes and be done.
Thanks for your honesty well done.
That's exactly the same noise as what's on mine.
Nice find, well done
Wow just sat wondering how many people have actually scrapped a perfectly good engine because of this tappin bet theres a fair few.. thanks for some great information
Thought my car needed new timing chain when i heard that noise thanks to you ive just unbooked my car from the garage appointment 😂👍🏻
We changed the hydraulic lifters.. but still it the sound didn't disappear
I believe these 'twinport' flaps are fitted to these Vauxhalls, to enable greater use of EGR. Therefore reduced emissions
Unbloody believable!! Thank you so much for sharing
🤣
nice one. would come to me as “mechanical” from auctions, this is how we make the big bux. 👍🏼👍🏼👍🏼 well played brother.
Thata amazing alan ...I bet a lot of people out there would right there engine off.. I've heard a few of these corsas like this ..... Great detail pal 👌
thanks paul
Nice to see the vids coming in.
thanks steven
Well done alan, a great vid for the memory bank.
Thanks 👍sparky
Absolute legend, had this issue fir a few years, was always wondering when it would blow up.. problem soon to be solved.. 👍👌
I e done the same
With my
Mk3 mondeo,I took the manifold
Off to replace the rubber pipe that splits and causes the revs to increase,I couldn’t get the old flaps out to replace them,so for now I’ve just pulled the vacuum pipe off,but for my
MOT it will be replaced,as it may fail emissions-
I am going to put a brand new
Manifold on soon though
Mate you’re a genius you need promotion, can fix fords blindfolded with one arm, can use tech and make content, can also fix Vauxhall’s 😂 and some eye candy on a few vids 👌 pure genius. I could bore you about when I was a young trucker down your neck of the woods at the radiator grill ( Huntingdon) 🤣🤣 it was terrible but they had a strip show 🤣🤣 allegedly ( I was asleep in truck ) but I’m 46 now and been fire fighting for 22 years 😮 all the best amigo
🤣thanks rich, appreciate it
Great job Alan, very well done Sir👌👌👍🙂
Thank you, Cheers pat
always a great video with you Alan!! Thanks
thanks mike
I’ve had it a couple of times on a corsa … but strangely only on the 1.0 3cyl… maybe the manifold is set up diffrent on the 4 cylinder … great Videos as allways Alan 👍🏻👍🏻
cheers chris
That's nuts, Well spotted Alan.
cheers 087mail
Hello nice one Alan would not have thought of that ha
Top info as always. See you in about 4 weeks.
cheers chris
Cheers Alan good to know the info.i would have said engine too.i like when you have different makes of cars on the channel
Thanks 👍pasday
i had a 2014 corsa with this engine brand new 8 miles on the clock, didnt get this bad. since had a mk2 focus diesel, and now own a mk1 focus 1.6 petrol and a mk4 escort 1.6 petrol
Amazing! You're a great mecanic!
Wow mate that's amazing your right that could fool you into thinking that was an engine knock
Great vid you learn something new everyday 👍
cheers stephen
My merc engined v6 chrysler diesel had knackered flaps, they were metal, I removed them and welded up the holes. Lost a bit of consumption, but I gained a bit of power, but lost low end torque.
Great video and very informative , any mechanic on the planet would have bet his life that was a big end or small end goosed. Mental
😄
I thought the swirl flaps only BMW ….they remove them because the engine will ingest them …game over…….good find 👍
well explained mate. thank you for sharing
thanks joseph
driven the 1.3 diesel .Great car
Hhhmm very interesting, this must have caught out so many people.
Hi Alan, I can not see what you have done exactly but when holding the screw, it appeared you were wanting to blank it off on the wrong side. Do blank it off on the engine vacuum suction side however. Otherwise you have now created a vacuum leak , which will arise when the solenoid is allowed by the ECU to let the vacuum pass through 😁Mixture problems will arise. Hope you did it all right. The safest way would be: Reattach the vacuum hose to the solenoid. Detach the hose from the vacuum actuator. Then blank off the vacuum hose. Leave the vacuum actuator unharmed, since apparently the flaps are in the correct position when the actuator is non vacuumized. Regards from NL
yes correct, thanks marinus😁
Hi Alan & Marinus, my daughters 1.0 petrol corsa is having this issue. I want to do as you guys are saying, but before I do, can you tell me please:
Did this ever cause a side effect or knock-on problem? (Pardon the pun with the term "knock-on"! 😂)
And - am I correct in my understanding that you only disconnected the power fron the little vacuum actuator and remove the hose but leave it open ?
Sorry if I'm misunderstanding.
Thanks so much for the videos and the help - it's brilliant 👌👍
Denis
@@denisbiggane6981 denis, there is a solenoid and a vacuum actuator. The solenoid is the thing with the electrical wire connected to it. Leave the electrical wire on the solenoid and do not detach it. The vacuum actuator does not have an electrical wire. It only has a vacuum hose coming from the solenoid. In order to put the vacuum actuator out of service, you should detach the vacuum hose from the actuator. But you should blank it off as described above. I do not know any side effects when doing this, you should ask Alan about that. Hope this helps.
@@marinusapeldoorn6631 That's perfect - thanks a million for the help 👍
@@denisbiggane6981 regards from NL 🤗
I had a mk3 2.0 mondeo and I changed the flaps in that manifold and it was a bit of a pain in the arse tbh. My mk4 I bought the complete manifold as it worked out cheaper than buying the flaps and gaskets seperate. I think the replacement flaps are plastic I'm not sure.
Holy S... I've never heard what bad swirl flaps sound and I've actually wondered few times that how the heck do you even know if they're going bad as it's a thing obviously in so many cars. I never ever thought it would sound like engine that's going to die within 1000km's 😁
You're like a Columbo Alan! Real detective 😜
😁
already had a scrapyard engine by the looks of it. red paint is a dead giveaway.
2015 wife Opel Corsa was ticking and I drive it and ticking eds when motor braking.Evap valve ticking.
holy shit i just had timing chain sorted ( sounded like a chainsaw starting up so did need doing ) and it still sounded like this and thought my engine was screwed as i thought the timing chain would stop this sound if u dont mind the tap is it still ok to drive as is ? or could it lead to damage ?
Well done doctor Alan another patient cured lol.
😁
Nice one Alan 💯💯👍👍
cheers charlie
My Vauxhall Insignia 1.8 sounds like this and it has always annoyed but now I believe this could also be the issue on my car.
Bet loads of these cars been incorrectly scrapped for “knackered engine “ when it’s these plastic flaps.
Daughter Had same car. Timing chain snapped. I rebuilt engine with new head then Sold it. Timing chain snapped again 6 months later. When I checked service history it had already had a timing chain fail before she bought it. So 3 chain fails under 70k miles. Absolutely ridiculous quality. . It also had this rattle. I disconnected flaps to keep it quiet.
You know its not the flap making the noise right??? its more to do with the fuel/mixture etc due to the flaps being in the wrong position to where the ECU expects it to be.
Hence the knocking like detonation sound or big end bearing sound..
the noise from the twinport is also when the engine is cold and when it is warm? I have a 1.4 xep, and it is noisy, whining, only when cold, the distribution and the gauges are changed
Easy to condem the engine hearing that
Interesting, I hear something similar in 1.4 engine the miles very low it's not as loud as this but this has me wondering if its similar to what ur showing.
Thank you for posting 👍
You are amazing maaan finally I know the reason of my car ❤️😍😂
Great video mate very interesting
Great video ❤❤
thanks dean
Just had the same issue and I just tapped the star lock washers down very slightly and the noise has now stopped 🤞🏼
do you know if the insignia 2.0 cdti could also have the same problem? THANKS FOR THE REPLY.
Ah man. Thank you!
That's a good thing to know, my 1.3 Diesel Corsa Ecoflex is making an odd sound but not that, mine sounds like a squeaking type noise when running or idle, sounds a bit like a fan belt would that needs tightening or something , a garage suggested it could be the turbo !
Have u sorted it out I’ve literally got the same problem??
@@shanu_yt2531 yes, mine was making a funny noise which turned out to be the injector seals and the excess smoke / bad starting from cold was glow plugs and it wasn't cheap to fix :(
Brilliant video I thought my engine was knackered saw this. Tried it tapping stopped. AMAZING THANK YOU. can I ask does it matter which end of pipe you blank with screw.. Thanks again 👍👍
I have a different sound, which I now have found out is a lifter arm, so off comes the camshaft for the inlet side, so I can change that single lifter which is clicking on mine.
Gonna do a complete chain shift as well, since I dont know when it's been replaced, and I need to do the oil pump at the same time anyway... Sooo yaaaiii... :D
I have a friend with that exact noise on a 1.4 that looks like that engine with an extra cylinder. Although, if we pull that hose off the noise is the same. He has driven with this for a long long time and I’m thinking if the flaps could have come loose or something and flapping around in there without the control holding it back. How are your thoughts on that?
Hi im stuck!! My vauxhall corsa 1.2 sxi sounds like an old diesel engine from the 80s do you know when a old taxi would pull up to collect you and you knew straight away cos of the noise, us it common my garage tells me nothing wrong but then today its juddering lising piwer then next minute its ok , dont think they both are attached but what could the latter be pls?
Great video Alan...do we see these swirl flaps on the corsa E
Thanks that’s great!
Alan great job awesome and very smart investigation u ve done . Wow you thought me something new Sir thank you
Keep it up 👍
Nice find and cheap fix. Just wondering if now it will use more fuel ????
chances are it will
I’ve got the same problem with mine same car year and engine rattles on start-up . And sound like bottom end going . going to check mine tomorrow
the oil filter element in those corsas get blocked and sucked in causing oil starvation..might be worth checking that too
It’s the solenoid valve making the noise
the flaps inside the inlet manifold are rattling
That sounds rough AF
You should have had the secatary too explain ,,would have been so funny 😆 🤣
🤣
If you can put up with the rattle will the engine be alright? Got one with the exact same rattle.
Hi Alan am have 1.6 petrol zafira eco flex am get same sound exactly 😮do no what’s wrong 😢 thanks
Hi Alan, thanks for sharing but at the start of the video u mentioned how important swirl flaps are in terms of better combustion and fuel economy, so assuming now the default to the open position permanatly, how has this effected the car fuel economy taking into account what u said at the start?
Thank you again and a good find.
Kind regards JAY
hi, yes much higher chance of increased fuel consumption but alternative is to replace the inlet manifold
@@alan4xHi my Corsa is having this same issue so thank you very much for the video. How much do you think it would cost to replace the inlet manifold?
Had the exact same noise, turned out it was the water pump, replaced it and noise went.
Nic video sir
Alan.how did you first discover the swirl flaps rattling,was it using a stethoscope?
if you put your hand on the inlet manifold you can feel the tapping
Brilliant 👍🏼
You wont believe i am having the same issue on my corsa ecoflex 2012 model .can u update a video on how to change the manifold??will b really helpful
I left the uk now, surely someone else on you tube will show that
How you disconnected the hose btw.. i tried to diconnect but its so tight and sad to say i broke the connection.can you please tell me the name of that part??
Its probably for emissions reasons, leave it disabled and it may fail the MOT emissions test, either now or some point further down the road. If it were my car I would probably pay the extra for a new inlet manifold, as long as it wasn't crazy money. What am I talking about of course is crazy money, probably 500 quid for the manifold and 200 quid for fitting. :-)
They call it 'twinport'. The car closes the flaps over on half of the inlet ports, to allow it to use more EGR
🤣well just connect it back up for the mot test
Hey Allan i have corsa 2011 auto i have done same thing but sound is still coming
And now my enguine is viberating
@@user-ef7tq3eq6s close the vacuum hose with a nail or bolt
Yes this is a real problem with this petrol engine and other makes and models with swirl flaps thst have been constructed poorly. Worst of all with this engine it sounds just like a chain rattle.
I have a 2012 diesel ecoflex same noise even with the eco button on goes like shit off a shovel even at 98.000 mls ok its a little noisy just crank radio up still 60 -70ish motorway millage mpg as long as you keep on top of the dpf by 1 or 2 good hammerings up and down the motorway each week for 30 mins will keep it sweet but you must change the oil air filter keep tyres good advantage good millage no tax low insurance
Dont even own that kind of car, just want to see Alan bum around
🤣
Hi Alan
Is the same thing with Vauxhall Astra 1.4 Sxi as well
I’ve been told it is a timing chain or tappet lifters
When you disconnect the vacuum pipe do the flaps spring to the open position? Sounds like they do if you have full power. 🤔
yes they will all be fully open
Hi Alan, my corsa sounds exactly like that and the garage have told me that the engine is on its way out - the only difference is that mine occasionally misfires and then sorts itself out again. Could the manifold cause it to misfire randomly? Thanks
Mine s got the same issue with missfire..did you find the issue with yours? I had a lot of different things told from different mechanics
The inlet manifold is not a mandatory part or the engine after All....
What’s the name of that part
Think they eventually start to brake up and bits of the plastic gets sucked into the engine
Omg cant believe how much noise they make when they go faulty and can totally see why someone would be able to mis diagnose it for being a engine bearing rattle lol.Great find btw top work as always
I have them on my s60 d5 mate but a stupid little arm that wears out an it's for ever popping out, mines been jammed in one position and I've never had any issues with it being jammed
😁
So in doing this are the Inlet flaps then in the Open or closed position? Tia
Hi Alan only you can help !! I have knock from the fuel cooler on my mk4 mondeo - it’s loud under the floor but not from the engine - the cooler has been replaced and so far two garages have never heard it before and can’t find a fault - the car drives great .It’s a 1.6 econetic.- any advice would be great thanks
alot of corsas sound like that
Did blanking it off last? my wife car has been making this noise for weeks now.
yes blanked it off and car has gone and never came back
Corsa e?
Hi mate can this happen on the 1.2 also
to this day, they haven't invented any add on that will not brake and make your life miserable after some time.
