I replaced the thermostat in my 2005 Duratec 2.0 16valve and while at it i removed all the swirl flaps in the manifold with no issues to the running of the engine. It runs perfect. So saved myself a few quid.. I was told to do this by a ford mechanic and he was rite.. Took 3hrs start to finish. Was easier to remove the radiator and that gave full access to everything. Great video..

Has he blanked hole after flaps bar or just removed it all? Thx Matt

Hi! I did the replacement job at the weekend. - My Mondeo MK3 had about original 183.000 km (2005 2.0 Petrol) - I could hear only a light noise, but the problem was there. - The rod and other parts were undamaged so I've replaced only the 4 flaps. (The flap shafts were damaged) - There was no second screw on my Oil pipe bracket. Removal was not necessary. As a hobby mechanic the whole process took about hard 10 hours! The intake manifold removal is a huge job! (I have renewed all cable clips etc.) Now the engine is quiter, there is no diesel sound. In my opinion this problems comes after 200.000+ km . Thank you very much the video and the instructions!

[@The-Advent-Sabre]

Bought a Focus CC last weekend as of the date stamp of my comment... Had it 3 days. Engine light comes on. P2008 faulty code. Intake solenoids were shot. Bought new ones. Solved. However..... I stubbled onto this video when I was investigating the solenoid issue. And boy I'm glad I did. You just saved me a few hundred pounds. Out of curiosity I decided to take a look at the intake manifold. (I had the bonnet open for the solenoids so hey) I think I was very lucky... 2 out of the four flaps were about to fail catastrophically!! Entirely new manifold is on its way. Thank you.

[@williamchristian2491]

I have a 2.0L 2005 ford focus and took the intake manifold off and removed the flaps of death. It's an arduous task with many sensors that don't want to come loose and none of them are the same! So each one has to be done differently. Most of them require pushing in the middle of the plastic electronic part and pulling, but not all. Like me, you will have to look at them and figure out how to release them. Ok, some hints on other things: 1. Consider replacing the PCV valve and put in a new PCV hose. These are not cheap if you get the proper parts (mine cost $15 for the PCV valve and $28 for the hose). Normally you cut the PCV hose off to release the intake manifold and then replace it, because getting a pliers down to the hose clamp and pulling the hose off the PCV valve is an enormously difficult task. Just cut and replace. The PCV valve has a plastic clip holder that you must not break! If you do, you must buy the entire oil separator to get a new one and these were $33 on Ebay. To pry off the clip, you need to remove the oil separator which is held on by 8 bolts, two of which you must have an 8mm wrench to release and the other 6 you can use a ratchet and socket. Then use a small small screwdriver and try to pry the clip off - some people use a knife. Be careful! Clean the oil separator with brake clean. Then put the oil separator back. At this point, my suggestion is to connect the PCV hose on the bottom (hose clamp) but on the top- install the PCV valve on the PCV hose (hose clamp) and you must leave the plastic clip on the PCV valve then when you get the intake manifold on the car you can then just press the PCV valve on to the oil separator and then using the long rod that held the flaps of death just press down on the plastic clip to snap it on. Otherwise, it's almost impossible to put the PCV hose on the PCV valve by using a pliers on the hose clamp with such limited space. 2. Clean the MAP sensor in the intake manifold. You need an electronics parts cleaner for this - I used CRC Electronics Part Cleaner (wal-mart). The MAP sensor is located near the bottom of the intake manifold, and is held on with a 20 Star screw. So do it while off the vehicle. kzbin.info/www/bejne/n5TKkn-fetSinsU 3. While the intake manifold is off the car, clean the MAF sensor with a special MAF cleaner. The MAF requires special care, so handle it such. It's held on by two 20 star screws. kzbin.info/www/bejne/i2qzhWuQg5iHjqs 4. Clean the throttle body - and there is a special cleaner for this also. Wal-Mart has the MAF and Throttle body cleaner in one package in their auto parts. 5. Use poster putty or some other stuff that will seal the plug hole where that square rod was. 6. Replace all the vacuum hoses on the intake manifold while off the car. So much easier! 7. Clean all the sensor connectors with the electronics part cleaner. 8. Replace the manifold gaskets with new ones cause you don't want a leak there! 9. The manifold intake runner control (MIRC) is basically useless at this point, but the electronics need it. The control has a vacuum hose that connects to the front of the intake manifold - make sure you replace this. The second hose goes goes to the vacuum actuator that controlled the flaps of death. What I did was connect this hose to the plug on the right side of the MIRC, because that hose now serves no purpose, neither does the actuator. 10. Use a torque wrench on the intake manifold bolts at 13 ft lbs. All other bolts or screws snug. 11. You need to reset you electronics to get the car to work right. After doing all this work my car just died - not holding an idle! Disconnect the battery. Reconnect. Turn on ignition switch (not to start!, just to run) and let it sit for about 30-45 seconds then turn off. Try starting. It took me some time and feathering the throttle to get it to run, but then bingo, the computer saw the changes and fixed itself and the car's idle was ok.

[@williamchristian2491]

Nope. Don't use poster putty. Use SteelStick or other epoxy blend that works to putty but drys hard. Make sure you leave a space for the actuator.

[@Gargoilunit]

Thank you so much for this video I recently replaced the pcv valve on a Mazda 5 hoping to reduce the oil consumption and this video with the manifold replacement video was a godsend. The reason why this video was so important is because I removed the swirl flap actuator during removal of the manifold. I then put it back with the swirl flaps closed and thought nothing of it but looking at these videos again I wondered if I had the rod 90 degrees out and the flaps should be open.. Sure enough it was and the actuator wasn't doing anything. Luckily only driven the car a few miles before my conscience got the better of me. Luckily you can remove the actuator whilst the manifold is still on the car. I checked my swirl flaps and they all seemed to be in good condition with minimal movement so I've left them in. Time will tell if that was a good decision or not! Car is a 2010 Mazda 5 with 100k miles on it so about 160k Kms. Thanks again for these videos 🙏

[@iwd1705]

At least Ford sells the flaps. There arte other manifacturers with the same issues where you'll only get the complete manifold for purchase. And it's not like they will sell it for a good price. They always want to make them golden.

[@gregtaylor5980]

Thanks for the video. Yesterday I removed the swirl flaps on my 2.0 ltr focus but it did not have the metal carrier guides, which I assume is the latest manifold version? However the swirl flaps had excessive movement so they were taken out. The rod appears to be in good condition without wear, which I will keep hold of. I also replaced the psv hose (£43!) which was split very badly when I consider its only covered 76k.The psv valve was also replaced. During the first road test it doesn't rev independently when stationary and is smooth when changing gear as the throttle pick up used to cause slight knocking due to pick up lag. Just to mention on the focus it appears a little tighter when removing the manifold as I found tilting it was my only hope. All in took over 5hrs as removal was hard especially the centre bolt. Thanks again for the clear instructions and the tip on taping the socket to the bolts on reassembly. Cheers

[@christianolsson834]

I removed the flaps completely and it runs just fine even after 510000 km.

[@CraigsDIY]

510,000 km? Good effort... what else (major) have you had to replace/fix?

[@christianolsson834]

nothing on the engine. But new shocks after 350000, new dual mass flywheel after 300000, and the usual bits like brakes etc that all cars go thru. High quality long life car that doesnt necessarily "feels" so. Mine is an ex Danish police car, there´s something done to the engine, faster than the V6 version anyway. One interesting thing is that the multilink back suspension seems to last forever though. Never done anything to tht suspension in all years. And we live on the countryside...

Hello, this comment was awhile back but still relevant; What do you do with the solenoid that attaches to the intake manifold that engages the actuator? Did it throw off a CEL code removing it?

[@billiardball9650]

hello did you have to seal up every hole in each cylender or just the one that meets the acuater

[@judgestacker9472]

Same engine different country. I also removed my flaps with zero problems. All of my modifications have actually gotten me and extra 2mpg. I removed the flaps and rod but replaced the actuator so that there is no check engine light and no botched vacuum leaks. I have also eliminated the EGR valve, installed an intake kit and an aluminum throttle body. I am going to soon install the manifold off of the 2.3L SUV that has runner control and use the swirl flap circuit to control it. This will give me dual length runner and that is far more effective for power and fuel economy than the swirl flaps.

[@CraigsDIY]

Interesting. Thanks for sharing. Would like to see more about upgrading to the 2.3 L manifold and converting the IMRC's to the old control. Won't you need a re-map?

[@judgestacker9472]

You will not need to remap as in change the MAP sensor arc. When I install it I will use the control circuit of the old tumble flaps to operate the IMRC. Once I get a tuner, the one I am going to get supports altering how that circuit functions and I can set the RPMs that the IMRC changes at. I want to see how it will operate on a stock tune though before I change it. I'll keep you updated.

[@hardyXXL]

Can you give us some more info about the actuator? What did you replace it with in order to avoid the CEL. I've been thinking of removing the flaps myself, but I wouldn't want to have a CEL always on.

[@CraigsDIY]

[@kpo42641]

Hello Craig, just watched your Duratec manifold R&R video and now this one on fixing the swirl flaps. Interesting suggestion to just not re-install the flaps due to cost and take the little fuel economy hit. I may consider that after inspection once the manifold is removed. I mentioned before you seem to have good video capture and editing abilities, it really makes for a high production value, especially with the post recorded voice over. I think I'm going to try that also on my next repair job. Thanks, KPO

[@darylkinnett675]

How did your manifold turn out removing the flaps? Was going to get started on this myself over the weekend. Thanks for any information.

[@joshuamackay7581]

Kris Lynette I’m currently doing the delete method on my 2002 Mondeo 2.0 Duratec HE as my flaps are around 5x as bad of movement as this video after inspection tonight. It has taken me 3 months to get around to it as I suspected flaps to be the cause and had to weigh up options before jumping the gun. Will update you tomorrow once car is together and another update after a week or so with a flap delete. Note I’m not that experienced with cars and the removal task alone took nearly 6 hours with several 1/4 socket extensions written off as the 3/4 set doesn’t fit where bolts are

[@joshuamackay7581]

Okay, so I finished it earlier on today, the rod was an absolute prick to remove! And there oddly was only a plastic casing with all this ground up looking plastic in centre between inlets. I had to clean all of it down including between inlets were rod was due to how worn it was for the epoxy to grip. I filled every hole the rod went through and left the agitator on attached to side but left the white clip piece out as well so no cel code was thrown either. Initial test drive so far so much more responsive, picks up speed faster. I have noticed a slight delay or something along those lines if giving gas backing of n full gas straight away. Will see what it’s like for the next few days but seems to be running beautiful. Have not noticed a decrease in fuel consumption yet but will be able to tell later on down the line. Give it a go if you haven’t already. Also massive thanks to this channel. Has helped me through my journey with alot of swearing i got there in the end lol

Well this video give me all the info on how these flap work...so as for me in central america parts are expensive so i disable the the flap system and uplug the solenoid and tube....leaving all flap open....bc the electronic throttle control the system as a regular car....car run super smooth and lots torque is nice and i get a extra mpg...first it was bugging and starving for air especially when i slow down and accelerate....

[@DavidB445]

Another great video. I removed mine completely as taking the manifold off was hard enough, I wasn't doing it twice lol. Never noticed a change in fuel consumption or running of the engine. As you said, some report a slight increase in consumption and some even say there's reduced power/torque in the lower rpm but I didn't really notice anything.

[@unregistredhypercam]

My car had 70,000 miles on it and the flaps were not worn at all, they still fit tightly in the housings. I removed them anyway, the car runs just as well as it used to, maybe even slightly better. I also installed an oil catch can because the oil seperator on these cars suck too much oil into the inlet for my liking. Might be why the flaps had so little wear in my case.

Same shit like on BMW Diesel, the Swirl flaps gets loosen and they fall into the intake valves and damage the engine. The intake manifold is built like this, plastic, the swirl flaps are of Metal. Best way to protect the engine is to remove the swirl flaps, the engine will still running good and withhout any issues.

[@yairf]

Tremendous stuff ! I have a 2010 Focus Mk2 with 2.0L Duratec engine. It seems like Ford gave up the flaps, and placed a "Runner Control Valve" which seems to do the same job, and is very easy to replace (Ford #BS7E-9J559-AA).

[@roycai8895]

I thought the valves controls the flaps ? I just bought the valves because I have the P2008 code on my 2007 ford focus, but now I am thinking of de-flaping it which would make the valve pointless. (I guess the good thing is it'll shut off the check engine light)

It ran no differently, as you can see in the video my flaps were a little loose and would have been vibrating, but working fine and no reason to think they would affect performance. It is just about dealing with the danger of them failing and killing the engine.

Was doing a pcv valve on my Mazda and noticed the swirl flaps were stiff to turn, jammed them open by putting a screw in the solenoid side, did not reinstall solenoid so far so good

The flaps are open by default (when actuator relaxed), so from what you wrote it sounds like you have jammed them closed.

[@djiankennedy]

I completed this job myself with the help of a friend a few years ago, buying a complete set of new flaps, and had ordered a new but stupidly mis-measured the length of the original and in the end turned my (already quite damaged) rod around and threaded it through from the other end. I now want to re-do it with a new rod, but I'm interested if anyone can provide the exact dimensions. I bought one that was 4 x 4 mm which seemed to fit ok

[@CraigsDIY]

I measured mine as 3.5 mm square, which is not a standard stock size, and I couldn't find any stainless rod that would suit. I'm pretty sure 4 mm sq won't fit the flaps or bearings. If you could find the right size you would just buy a meter or so and cut it to length. It should be a high hardness stainless, not 304 or 316.

You sir have probably the best user content quality I've seen on a diy video.... Ever! Just bought an 07 focus 2.0 duratec with 55000 miles and am really worried about these flaps. My car already has a pcv failure which led me to your videos. I also have two bad pulleys and a stuck thermostat or bad coolant temp sensor. I'm not sure because the car will warm up to temp but takes a a little. However once it warms up it seems to pick when it wants to open the t stat and usually when I'm putting around town. It's random as sometimes heat is fine. So I'm pulling the manifold and doing a tstat while I'm there doing pcv. Contemplating deleting the plates but worried about if I fill the holes with epoxy, that it might come out or I'll get a check engine light as I need emissions.

[@CraigsDIY]

I would just inspect the flaps (the rod particularly, as shown). Decide what to do based on their condition, if they're fine then leave them, maybe end-for-end the rod like me. If you do remove them I doubt you'll get a CEL, so long as you put the actuator and its connection back with nothing to do, the effect of the flaps appears to be subtle. Almost certainly tstat failed, so long as temp sensor giving sensible readings (ambient temp when cold, and up) it's probably fine.

[@jakobmsattler]

When doing a flap delete, do you remove the rod and keep the actuator, and then plug up the holes? will it affect the idle(make it unstable)

[@CraigsDIY]

Correct. Others report no noticeable effect. But it must make some difference.

What is the the white piece hooked to the acuator???

[@tomascasadoroa3857]

hello, how do I know what gen my duratec HE is? and if it has this problem?

[@deantaylor5677]

Excellent videos. I am the the US yet many things cross to my 2006 Focus ST with the 2.3l duratec. I just removed the manifold and have removed the rod and flaps. On another KZbin video the guy fills the holes between the runners with epoxy. Is this necessary?

[@CraigsDIY]

Not necessary to fill the holes. But it wouldn't hurt.

great job, regards from ARG

[@jeffreygraham3364]

Thank you for this great video. I really appreciate the format of audio edited with video. Easy watch and a good use of my time. I do have an important question.about option 3 as I will be choosing this option. Will this trigger an engineer code? I live with in the metro area of PDX Oregon. We have emission test every 2 years and check engine lights will fail the vehicle. Does removing the glass create an engine code?

[@CraigsDIY]

No. In theory the ECU should probably have a different map but in practice nobody reports any issues. It certainly won't effect emissions or set errors.

[@marcobecker906]

who, thats a good video!!!!! thanks.

[@allegory7638]

Anyone know the Ford Part number for the flap assemblies?

[@fredroe7556]

If anyone knows where i can get the white part hooked to the arm id appreciate the info my broke

[@Trevor-Ca]

How do I know that my focus needs this service? Are there any signs, noises or symptoms? I had thought about the PCV valve, just putting a filter on it without connecting it to the manifold, I don't know if it's a good idea.

[@simonjohnhinton1938]

Changed mine on my ghia x mondy. You don't really need them as it's only there to keep things smooth at low rpm. I will be getting another manifold and remove them completely and fill the holes with araldite, all the flaps and gaskets came to about £65 and we're easy enough to do.

[@helloukw]

By filling the holes, you don't mean the holes where flaps were, right?

[@simonjohnhinton1938]

helloukw no only the holes where the control rod (where the flaps attach to) pass through the intake manifold. Once the glue is dry you'll need to smooth it down so the intakes are nice and flush for optimum airfow.

[@fherdzbalite16]

hello.. I have the same issue in my flaffer and need to replace.. may i know where can I buy those new flaffer that you put.. I have Ford Focus hatchback 2.OL 2007.. thanks

[@alexcintas8792]

Were these on the 2008 USA focus?

[@adrichowkins6655]

Can the swirl flaps be deleted completely rather than just change them for new ones

[@spiffs6320]

A1 plus plus video So helpful Thanks so much

[@deanaf]

Anyone know if this applies to the Ford 3.0 motor?

[@pauldarrigo4395]

I have a 2005 Mazda 3 2.3 Removed the flaps and the car just won't run right. I did NOT seal the holes between cylinders. I had a tune done and it still will run oddly. When cold the acceleration is hesitant. Even when warm sometimes I throw a code and have sluggish acceleration. At this point I may just replace the flaps or intake with a used one. Any thoughts would be appreciated.

[@Cheordig]

Great video. I have a 2009 SMax 2.0tdci. Is it likely to have flaps?

[@5cbst]

Is this why my focus is misfiring in cylinders 2 and 3?

[@Bket666]

very nice video i have mazda 3 2008 with 230 000km do you think is time to remplace that or my car do not have problem in 2008 ?

[@michaelszczys8316]

You only have to seal up one end of the rod hole when deleting? What is recommended for hole plugging?

[@CraigsDIY]

There is only one end. You could also plug the internal holes and try to make the sidewalls flat for the sake of airflow, but really best to replace the flaps if you care that much. Use an epoxy or something like JB Weld.

[@pauldecouto6031]

Does removing the swirl flaps make your check engine go away?

[@nicksimpson2832]

Amazing video. Is it possible to pull the rod and remove the flaps only to reinstall the rod (without flaps). My thinking is that reinstalling the rod (without flaps) you will plug the holes that would have been left in the manifold runners if you didnt reinstall the rod. You remove the compromised flaps, save yourself the trouble of reinstalling new flaps that will wear out, and not create holes in the manifold. Thanks!!

[@CraigsDIY]

You could, but the rod is really what's dangerous and it is what actually fails as shown in the video. Removing the flaps will probably slow the wear on it but I'm not sure how much. As to the holes between the runners, you could also seal them up with epoxy to isolate each tract but honestly I doubt it would make any perceptible difference to anything.

[@larrylackey2083]

loved your video! we just bought a 2010 ford focus and found out the actuator isnt attached to the car, the previous owner took the rod out and the flaps. do you know we can eliminate the p2004 code by attaching an actuator and attaching the vacuum hose to it, or splice the vacuum hose to another vacuum line? you would be doing us a great service if you happen to know the answer to this question, thanks in advance!

[@CraigsDIY]

I think it's sufficient to just connect the electronics up, if the PCM sees the right electrical circuit it should be happy, it's not sophisticated enough to actually know what's happening. If the existing hose is available you could use it and just leave the actuator working nothing, on that note check the old mod sealed up the hose nipple on the manifold.

[@DavidGonzalez-uo6pf]

So can I just leave them open or remove the flaps? Is hard to find those where I'm at.? Is for a Mazda 3 2010. Thanks mate

this is my favorite ASMR

[@MarcioR_Olv]

Hello. Did this defect cause the engine to malfunction, or did it just cause noise?
