Hi! I would love to see a start to finish swirl flap delete job, showing removal steps on a 1.9jtdm 159/brera. Not much content on the subject so should do you well on views! Keep up the good content!
@@ItaliaAutos me too, my son bought a 147 JTDm that had been repaired after ingesting a swirl flap and bending a couple of valves. I couldn't find out if the engine had been de-flapped before he bought it but curiously it has a slightly rough idle and there seems no reason it should be idling roughly. Perhaps it has been de-flapped but I don't want to pull the bastard apart to find out. Is there any other way to find out on these 16-valve flappers?
Hi thanks for sharing such informative video my swirl flap motor is burned is there a way of making like a emulator that can fool the ecu that all is fine Thanks again
Hello guys. Recently been interested in buying the alpha 159. Found jdtm 2.4 diesel,auto, with around 190k km. Looks in really good condition, interior aswell. It has stage 2, swirl flaps off, egr + dpf are off aswell. Aluminium coolant bleeding valve. Alternator fixed now and turbo had been repaired a year ago by his words. The guy has history of treatment claiming he done it every 10k. He's demanding an high amount than the usual price. Claiming that its because of the time and money spent which is obviously acceptable. My question is, What should I check with him about the car and be aware of? I've read on some forums online that the model had a problem with green and red cooling water,or something like that. And been told to check suspension springs + check for rotten. aswell with the swirl flaps,egr and dpf, and as I've said he modded it off. Is this car actually reliable? Big amount of money to spend as I'm looking forward to keep the car for few good years and who knows maybe forever 🙏 Sorry in advance if there's abit of lack in language, thanks in advance!
Hi - great video - thanks. When putting the manifold back together what torque are the bolts tightened to? I know the manifold to block torque but not the torque for putting the two halves of the manifold back together.
Hi mate, one of the swirl flaps was injested, just the one. They're plastic ones by the way, would that destroy the engine as well. I thought of changing the type like you just done. Or is there anyway of fishing it out. The one nearest to the egr valve, far right. Thx
Hey just seen your video I have done my EGR need to do the throttle body but the manifold is bringing up some codes Question is do I need to have the flaps deleted off the car will blocking all the holes would it bring up any faults now they have been replaced by caps cheers
I’m having problems with my swirl flaps and some of my local garages have told me the the engine would need remapped? I thought that they would just disconnect the actuator arm?
As I heard in restyled Alfas 159 (from 2008/2009 on) e.g. 1.9 JTDm 110 KW, those swirl flaps aren't plastic anymore. Is it true and is there still a possibility for those updated non-plastic (not sure from what material were they made) swirl flaps to cause problems, like breaking off and getting sucked in the engine? Thanks.
There have been flaps on BMW, Audi and others that would break and then fall into the engine and leave ugly marks on the piston and cylinder head. But on this type breaking swirl flaps are not very likely. The most common error, even on the newer generation manifolds, is the swirl operating rod coming off.
@@ItaliaAutos Thank you for the quick answer. Do you think it was only because of the clean-up or also because of the extra air? Because if so... I might look into doing that too, even though I never had problems.
Thanks for making this video! I've got a question, my intake had a flap missing and its not in the intakeport had it hasnt got a rattle sound, where coult it be gone?
Hi Neil. I have 2.4 just like this one. Are these swirl flaps controlled by vacuum or from the ECU? If I remove them, should I change something in the ECU too? Is welding better or this kit just work fine to block the flaps? Thank you for the helpful videos.
Thanks for the video. I have an intermittent fault with the engine warning light coming on. I get that loss of power. A friend lent me his OBD device and it came up with code p2075. Any idea of what you would charge to fix this?
@@greengrass9572 there all about emission controls and reducing toxic gasses. they should be closed up to about 2000rpm so if there leaking they cause start up and idle/smoke problems.
@@gunnarlandin3258 so....which is it? Is it good or bad to remove the flaps and block the holes? Does it idle weird and doesn't have much power on high revs or not when the flaps are like the ones on the video? Because my BMW 230d does exactly that. And can't find something with the diagnostic computer
I have a vauxhall vectra my swirl flap rod keeps popping off and im losing all power i have a replacement on the way do u rekkon it will stay on once the replacement is fitted
@@ItaliaAutos the rod came off so i put it back on and had them deleted but the rod has popped back off again its like the plastic connection is crap like the rods springing back off
@@ItaliaAutos they have been deleted i have checked they dont move when putting foot on gas but every time the rod comes off i lose power n goes in to limp mode
you dont blank the swirl flaps you just remove them and block the hole where they fit into the manifold. no warning light will come on. they will just be a slight low rage power difference. hope this helps. neil
Thanks for your awesome Videos! A lot of Alfa Owners/Club members from Germany are following your Channel! :) It is necessary/important to remove the flaps like in the video after i closed/delete the EGR or it doesnt matter ?
@@ItaliaAutos And what do you think about to open it all and block at this position? This is what my tuner wants to do beside deactivate EGR and do an map-optimization. Now im a little bit confused, because you closed and he wants to open it :D
@@marcodefelice200 Leaving the swirl flaps open has the same effect as installing the plugs. But it's a lot easier unless you have the inlet manifold off anyway. I'd not worry about it and just keep using the swirl flaps unless they really cause problems though. Unless your mechanic/tuner will make the modifications for free ;-)
@@giuistefanjr72 You get carbon build up to an extent that causes trouble when the swirl rod comes off and the flaps are permanently closed. But even then, if you fix the swirl rod with a repair solution like mine, the carbon that really blocks air flow will go out the exhaust. The rest just looks a lot worse than it is. Beyond this, as mentioned in another post, leaving the flaps open or replacing them with plugs is illegal. They are not there for fun, but because they improve combustion and emissions at part load. By the way, I'm the inventor of the the replacement bushings and rods that you can get as copies on eBay and elsewhere - original is www.swirlrepair.com. So I know a little about the topic ;-)
Hi there, I'm in New Zealand and dont have any Alfa specialists near me. Could you recommend a removal kit that I could buy online to give to my mechanic. Not looking to get a new manifold and im worried the plugs might not fit for my 2.4. Cheers
Best thing is to sort out the exhaust, as long as the DPF prevents proper air travel the engine and front will be blocked,drill DPF with just 1 masonry drill the whole way , the sensors will still work regen normally but no more front manifold and EGR blocked! I too live on a distant place and island with non of the stuff! My 2.4 jtdm is 130 000 km now.i not far from new zealand infact!also use proper engine oil like 5w30 for DPF low ash dont go with manufacturer 5w40 it causes block etc.
Hi, can you tell me how exactly the intake manifold come off ,because i try and the injection pressure pump mount it's bothering.I dont wan't to take off the belt. Sorry for bad english.My car is Alfa Romeo 147 1,9.
@@ItaliaAutos basically, at low revs a flap shuts in one of the ports to each cylinder, something to do with restricting excessive airflow at low revs to maximise torque. Then above a certain RPM, the flaps open to allow airflow into both ports to each cylinder to maximise power as more air is required... Something like that. I just wonder if these flaps in the Alfa system operates in the same way?
Hi there, I have a mk5 Astra 1.9cdti sri (150) and mine has these swirl flaps aswell. What is the purpose of blocking the swirl flaps? I understand its to keep the inlet manifold clean from that black carbon stuff but I mean if it was designed/built like this from factory, and you block the holes/flaps.. doesn't this cause any damage to the engine in another way? 😕 I only ask because I need my timing belt+water pump changed and I'm wondering if its a big thing to do, maybe get this done aswell at the same time if it will stop the flaps from doing any damage to the engine or a "must do" if you know what I mean? 🤦🏻♂️ lol
Hello thank you for this video Can you please share a link or two to buy this kit And a 2nd question for a 2.4 200hp whats the diametre. is it the same as 210hp Ty
For this particular type of manifold there are no separate swirl flaps available. But you can get a replacement rod to install on the old swirl flaps. swirlrepair.com/wp/swirlrepair-diagnostics/. That solves the biggest issue, i.e. the swirl operating rod coming off. Worn swirl flap bearings/seals can also become a problem at some point, but in most cases it's not that severe.
Here is a video explaining the function of swirl flaps: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-m5AviXgca88.html The idea is to have better combustion at part load. Whether or not that's noticeable I don't know, but they are there for a reason. You may also want to mention that removing swirl flaps affects the engine's emissions, so even if it saves some trouble, it's not really legal.
My conclusion is that unless you have expert knowledge and a fully equipped workshop like yourself, Alfa's are poorly engineered and not worth the trouble despite what Clarkson says.😃 Good channel though.👍
