Great video thanks. To clarify for people I think when he says 10mm bolts, the bolt head is 10mm (thread is m6). I used M6 x 16mm long bolts, I tapped the holes to M6x filled them with Gasket and used the bolt with asingle washer and they sat almost flush on the inside perfect fit 👍👍👍
Good comment
Fantastic timing, I have to do this on mine before refitting a replacement engine! Thank you!
Just did this on my 08 alfa 159, i had all the flaps but they came off very very easily. Your video saved me alot of headaches .thank you
Glad it helped
Did you have any strange noises from engine before removing flaps, tickling noise?
Tks for this vídeo!! Do you need to mess with the cam belt TO take out the mainfold?
Hi! How and where to buy those screws? What kund of sealant is it? Thx man! You just got a new subscribber. Keep the good work!
Great video as ever . I changed the manifold for one with strengthened swirl flaps along with a new EGR valve but I keep getting a P2013,error . The flaps are opening and closing and I’ve checked the loom. Would removing the swirl flaps help this problem or is there something that needs to be deleted in software to make it go away . Tearing my hair out as car has been in my garage without mot for 4 months now . TIA
I absolutely recommend to do this on every "plastic" JTDM. I did mine and have found two on their places, but third stacked above valve and fourth didnt find at all. Still mistery, where it can be. Maby previous owner knows. :) Friend of mine was not so lucky and his 159 engine is totaled after flaps flought through his engine...
So do not think too much and remove them !!!
Fourth one passed through the cylinder causing only minor damage. Weakens the compression a little bit on that cyl. Sometimes starting in cold weather on three cylinders and fourth one coming shortly.
Just have the manifold off mine this evening on first examination swirl flap has been removed already but the little round bar is still in there that the flap was on I suppose it should be OK what do you think
Hi mate can you tell me exactly what bolts you used instead of blanks (10mm self tapping bolts and washers?) My cars due to have the swirl blank and delete and I've bought the blanks but now I'm understanding they won't be any good. I Like what you gave done it seems more reliable than the blanks. Subscribed! 😎 thanks mate
Hi Neil, does the 159 2.0JTDM have also these plastic swirl flaps? I can't find anything about it.
Hello, I would appreciate your advice on below please if you can?
I have a plastic manifold just like this on my 159 1.9 jtdm.
1. I heard other Alfa owners say when de-flapping manifold car becomes sluggish at lower rpm range as its can no longer regulate air flow - how true is this?
2. I also have my car remapped with complete EGR/DPF delete (EGR in the bin, manifold blanked off), but its smoking a bit on acceleration, company who's done my remap advised that it must be a boost leak somewhere and pointing fingers at my manifold?
3. Would it be a better alternative replacing plastic manifold with a solid aluminum manifold from older GT/147 JTDM models p/n Pierburg 46823848 which has no flappage? keeping in mind that you can't split plastic manifold open for proper cleaning?
Thanks a lot!
Hi Neil, what would the process be like for the 1.6 105?
Hi, first of all, I love your content!
Would it maybe be possible to do a tutorial of removing and cleaning the intake manifold of a 159 fitted with a 2.0 JTDM engine?
I would like to do this to my car, but i have no reference material to go after.
Cheers!
same as the others diesel ones ive done pretty much,
Hey, great material - as usually on your channel!
Is the procedure similar with the older, aluminium intake manifolds? Also, when you seal the swirl flap holes with screws, do you need to thread them or does it hold with the sealant only?
The 10mm screws are just the right size to self tap. As you can see in the video I get a good level of tightness.
Hi there, helpful video. Do you know what the process would be to remove the swirl flaps on a giulietta 1.6jtdm. ave read that they are fixed and literally just slide out but im not sure. Cheers
No idea not done one yet
I tried to snatch my aluminium inlet manifold of my old euro 3 GT to use on my euro 4. The litle coolant "thumb"on the very right of the manifold side is stuck behind a rib of the bracket for the common rail pump. Even filed a notch out of the rib but stil can't get it out. Any sugestions Neil?
Great vid thanks. Where do you get the screws or what size are they? I know you said 10mm but are they self tappers? Thanks
yes
@Calan mckinlay did you manage to find out what the correct size to do the job was? Mines due to be done tommorow and need to get these bolts ASAP
Thanks mate
Senzor on the intake manifold is MAP senzor (manifold absilute pressure) not MAF (mass air flow)
Thank you!
The foult .. it is making a like knocking sound ? Sounds like the engine souds like bad bering.
Hi Neal
Can the plastic part to this manifold be split open to clean or is it just a matter of doing the best you can with it?
Also I've take it apart to remove the swirl flaps and 3 of the 4 have already disappeared, the engine has been running fine since I've had it tho(1 year) and there hasn't been an obvious moments were something has gone seriously wrong, what are you thoughts?
Thanks
Did you manage to open the plastic piece? I have to do it now on mine. Thanks
How long bolts are they M6 or M10 ??
Very good video .. Is it possible to fit metal intake manifold rather then plastic one (before facelift - 2005 - 2008) ? And I have heard that it can be done with intake from older engines (1.9 103kw, euro 3) which didn't have flaps ? Tnx
Yes it can
@@ItaliaAutos Thank You for a quick reply .. I hope that there isn't many modifications, different scrrews, that can give problems .. ? Planing to do it with timing belt replacement at local workshop
plastic and aluminium is the same flaps location ?
What about wauxhall insignia 2011 2.0 ecoflex it's same? And can you tell me what is better when remove it?
ı have heard that cdtı opel vauxhalls have the same problem and ıs sımılar fıx
@italiaautos could you please tell me what is the plastic pipe sticking out of the flap housing at 2.52ish? Mines has snapped 🤔
cooling pipe. if its snapped you need another manifold.
@@ItaliaAutos really? No replacement pipe available? Thanks...I guess 😂
Are the plastic manifolds replaceable with the earlier metal ones?
Yes, you can replace it with early style 103kW engine manifold - without flaps, or newer 110kW metal manifold. It aslo has flaps, but they usually don't go in engine.
But there is no reason to replace it - just remove the flaps and you are good to go
Are there any blanking kits for the plastic manifold flaps? Also Is it a straight swap to fit the aluminum manifold? I feel the blanking kit with the press fits would be more secure. Cheers.
Don't think so.
Hi, i‘ve heard that I need to take off the timing belt to get the manifold out of the car. Is that right? Greetings from Austria, great videos👍
yes i always do it with a belt change. but you can just remove the pump
I have just bought a 159 1.9 with 64000 miles on the clock is it worth getting this job done now?
Yes
Hi, is does the high-pressure pump have to be removed to remove the (plastic) intake manifold?
I always do but you don't have too
@@ItaliaAutos Okay, because I've seen it with the metal version of the intake manifold, it's necessary. Are all screws of the intake manifold accessible without loosening the high-pressure pump?
Can you just disconnect the actuator and leave the flaps in the manifold? would that be the same thing?
Nope far from a fix
Does the 159 2.0JTDM has also these plastic swirl flaps?
2.0 does not have problem with flaps, only 1.9
Is remap necessary if I do a swirl flap delete on a 2.4 jtdm?
No. But it would benefit from one
Is necesary to dissamble the fuel pump to take off the intake manifold of plastic?
No but I always do as I don't like the stress of leaving the cambelt tensions on 2 tiny bolts.
@@ItaliaAutos thanks for answering. My 159 2.0 has the problem that the turbo pressure sometimes falls or even can´t increase above 0.8 overhall in big loads like driving in a hill. So i think that some gasket or maybe some swirl is failing. I´ve already changed the EGR. Do you think is possible that something is wrong in the intake manifold? I think the videos manifold is quite similar or even the same as mine.
Swirl flaps are fastened with two screws on the axles. :)
Not on this.
You can also delete the flaps from the software...so that the solenoid won't be neded
You can't delete the flaps but you can tell the ecu to not use them.
Same for Giulietta 2.0 mjet?
Jtdm2 engine doesn't have them.
hey it would be nice to see the timing exchange in 159 step by step 1.9 / 2.2 JTS
Look at the 2.4 video guide it's the same as 1.9
@@ItaliaAutos I think about timing chain but 2.4 it is a diesel?Sorry for my english
@@filip3056 sorry thought you meant the 1.9 diesel. I'd prob never do one on the chain engines.
ok maybe someday you'll have the opportunity to wait and watch just like the oil temperature sensor in the bowl would also be interesting material greetings
I’ve got a low mileage Alfa GT 2010 1.9 does it have swirl flaps?
Yes I'd say it does. But with the metal manifold.
Some of the later GTs have the plastic manifold with metal swirls. My 07 does.
Hi need a little help i done the same with my inlet manifold following your video guide, now car is in limp mode with error code p2013 flow shutter valve, any ideas what it could be? Thanks in advance
Yep I know what you have done
@@ItaliaAutos whats that then? Everything is plugged in as it should be
What have i done?
Damaged the flow shutter valve when taking off the rod.
@@ItaliaAutos what part is the flow shutter valve?
Is that not a map sensor ?? Isnt the maf on the air pipe
Just me saying the wrong part
Can we swap plastic with the alum manifold ?
Never tried it sorry.
If the flaps are fine and don't look like they are about to fall off any moment now, do you really need to take them off? Isn't it enough to just give them a good clean and let them stay and do their job?
And if removed don't you need to delete them also from the ECU?
It's stopping damage further down the line as it will happen one day.
No urgent need to get a remap
Ivan take them off, three have just destroyed my engine. Having to replace engine to keep car alive (fingers crossed)
@@rve_rider741 I'm sorry for that. Hope that you find a good engine and make it run again!
Hey bud,
Did you have to do anything else on ECU after you removed them?
I am wondering the same thing. No one mentions that, but I read that the ECU can store an error about a broken flap so probably something has to be done go the ECU idk..
@@philipgligorov5848 i guess best place to find that out would be Alfa Owners Forum, as i am planning on doing this on my 159 some time soon.
@@shpucas Has to be done obviously. I wonder if I can somehow find out if these flaps are removed on my GT without taking the manifold out? Do you have any idea. I bought the car with 177.000km on the clock and have it for almost a year now. The engine is in great shape. It's 1.9jtd with 150hp.
@@philipgligorov5848 you could find it out by connecting ECU scanner, i believe air to fuel ratio would be different than normal at idle, as without flaps, you let more air into engine, thus your acceleration, torque, fuel eco, emissions would be different too.
@@shpucas Thank you, I'll check that out.
When they should fail? I've just bought one with 250k km and they never removed that flaps and I'm affraid.
Prob had a new manifold in its life. Some garages won't remove them they just replace the whole manifold
How can you tell if this has been done?
not very easy im afraid
Anyone had issues with the 90deg plastic coolant pipe wedged between the two parts snapping off? Seemed like the one off mine was badly fatigued and broke very easily on both ends. Seems like this part is unavailable from Alfa Romeo to make matters worse!
They just snap easily not available on there own
@@ItaliaAutos Yeah that seems to be the case. Very frustrating. What do you do when you break one? Replace the whole manifold or just plug the hole?
New manifold
@@ItaliaAutos I had a local machine shop create an aluminium replacement for this. If you are interested, he can do a run of these and ship them over (we are located in Australia). It will be a cheaper option compared to replacing the whole manifold.
Granite countertop!🤣👍
LOL
Hello, for be honest i like you videos, cause you have hudge knowledge about Alfa cars.
But unfortunetly you job is often not clean...
In this cas you damage the part when you pull the swirl off.
Realy not great
mechanics work fast to keep the cost down...i'm sure the job was fine with an off-camera tidy up. And besides, you try filming as you work, he's trying to do both at once. Shut the fuck up.
👍👌😜
Dzień dobry
Thanks
Oh, god, I hate the EGR and Swirl flaps!
haha it's a dirty job, yeah better clean first :D .. and work on a clean working bench and so on..
ha ha you should see my work bench now. piled high with crap.
Strange late 09 models haven't got one.
