In hindsight, I would recommend using a dab of automotive RTV to keep those small plastic shaft support pieces in place under the intake gasket.
To be clear, this was done at the customers request for an already deleted ecodiesel engine. With the programming that had been done, the computer no longer actuates this swirl valves anymore, and they only serve as a restriction.
Did a stage 2 delete, also had the swirl valves turn off, at 88,000km and still going strong after 130k, probably a good idea for anyone pulling the intake off is to change that coolant line going to the turbo.
Absolute must-do.
Thankyou and god bless
I live in Michigan as well do you know who did the delete tune?
Excellent Video. Is this a 3rd gen ecodiesel? I am getting code P200B. Dealer said to replace the manifold however I am able to get a tune done to leave the swirl runners open. Im not getting any acceleration issues or rough idling so im assuming they might be stuck in the Open position rather than closed.
This was a 2015/2016 model I believe. Sounds like you’re on the right track.
I'm in Michigan also, where are you located?
Where would you connect the vacuum line to install a boost gauge? I was told you need to drill and tap the intake manifold. I’m sure the closer to the turbo itself would be the most accurate.
No, you want an actual readout at the intake manifold. If you take a pressure reading as the compressor outlet, your not taking into account the pressure drop across the intercooler and tubing. Is your truck deleted? Than tap into the block off plate on the intake manifold where the EGR tube used to go.
Does removing the swirl valve shaft change the fuel distribution with a hole through the length of the intake where it used to be? Wouldn’t boost push the fuel mixture into other ports via the open area between each one? Or is the pressure constant and inside the intake ?
I’m having a little trouble making sense of your question, but to be clear, there is no fuel moving within the intake manifold. Fuel is injected directly into the cylinder as with most diesels. Bottom line, the intake manifold on this engine is strictly for flowing air. The swirl valves cut off or reduce air to one of the two intake valves, for the sake of air velocity and how it affects emissions.
@@tadsworkshop Does that mean fuel doesn't get burned when there closed or there should be no fuel in the cylinder?
@@PeterCieply no, not quite. There are two intake valves per cylinder. The computer uses those swirl valves to cut off, or reduce air flow to only one of the valves. Even if it were completely shut, the cylinder would still get air. And if you cut off fuel to one of the cylinders, this would create a dead misfire, like removing a single spark plug wire from gas engine. This is all an effort to manipulate air velocity going into the cylinder at certain times, which affects the emissions coming out of the exhaust.
Great video. Is there a way to reduce the soot buildup inside the intake? Does long highway driving help prevent buildup? I had a 2014 Jeep GC and it needed a new intake manifold due to soot locking swirl valves. How often have you seen this happen? What percentage of Ecodiesels will this happen to? I now have a 2016 Ram Ecodiesel. thx
I have a 2016 with 170,000miles..had to replace the intake at 155,000..was completely filled with soot due mostly to the emissions recall that was performed a few years ago...Other than don't idle for an excessive amount of time, there is nothing you can do..any sites that you were able to purchase delete equip. are now gone..The EPA is slowly killing these diesel engines...I used to avg. 28mpg, now I'm struggling to get 23..
I’m sorry I never responded to your comment. The soot build up in the intake manifold in inevitable for any stock, unaltered ecodiesel that isn’t deleted.
As far as the soot jamming up your swirl valves…..I can’t imagine that happening anymore than once every 100-150k miles. But that’s only an educated guess.
@@tadsworkshop Thanks for the reply. We had a 2014 Jeep GC Ecodiesel (Gen 1) (bought new) and the intake manifold had to be replaced at about 90k miles. We had just gone on an extended 5000 mile road trip and on the last day the "exhaust regen" alert came on twice, even at 75 mph. A few days after we got home the check engine came on and the code reader said "intake runners" or something like that. Took it to the dealer and they replaced the intake manifold under the extended factory emissions warranty. Otherwise it would have cost about $4K. The "exhaust regen" alert had always been coming on during the life of the vehicle. Very disappointing. Even the catalytic converter needed replacing at about 4K miles. Took it into the stealership and they needed to perform a forced regen twice to clean the DPF before the new cat. What a POS. I now have a 2016 Ram 1500 Ecodiesel and am wondering if I should sell it before anything happens??? The "exhaust regen" alert doesn't come on very frequently. Seems a lot of around town stop and go driving (without proper and extended heat cycles) plugs them up quicker as does long idle times. I was told by my dealer the Ecodiesel needs to run on the open roads a lot to heat the exhaust, apparently to help keep the DPF clean. Biodiesel is a no-no on these.Thanks again
@@robinsongguitars thanks for sharing your story on that. Where are you located? I’m curious if deleting the truck is practical or possible in your area.
@@tadsworkshop I live in California where you can't even fart without getting a smog check. Wish I could delete the EGR, swirl valves, DPF and DEF nozzle... Thanks for all the good info you provide.
Are you using a tune or resistor after you delete the swirl valve? If so which one?
An delete tune has to be used. Was already done before I got the truck. The computer monitors and receive feedback of motor and valve position, so there is no way to bypass this with resistors to the best of my knowledge. It’s not that simple of a system.
Hello.Could you give the part number of the magnetic position sensor? or the numbers about it and the manufacturer? I'm trying to find it on the internet, but I can't find it using keywords...
Hi. You can find them it the video description of this video I created. ua-cam.com/video/gmPfzRpfr-4/v-deo.htmlsi=57JP6_bLg-cG0RqS
But you should really verify the part numbers through the official mopar parts website, www.mopar.com/en-us/shop/parts.html
@@tadsworkshop I mean the sensor in this video at 1:17
Hey tad great video... any tips? replacing the intake on a 2014 jeep grand cherokee ecodiesel.. when i got to it the intake runner control motor is broken... im not deleted... do you happen to have the moter you took off? Or know of a solution
No, unfortunately I sold that motor on eBay some time ago. You’d have to check with the official mopar parts website to see if there is a part number for that motor…..or search eBay for used intake manifolds or if by chance someone is selling the motor by itself. If it’s in your budget, you might consider a brand new mopar intake manifold. I know it comes with the motor. If your budget is tight, you could see if the aftermarket Chinese clones of that manifold come with the motor.
@tadsworkshop I really appreciate the fast reply... I already got one of the cheaper intakes ($130) only thing it doesn't have is that motor 😭 didn't know it was broke untill I got in there... new Mopar is $800
@@-RON-DOMINATION- damn, your not kidding on the price. Believe it or not I could buy mopar ecodiesel intake manifolds on the official website for $320 a few years ago. At that time, new motors were 10k and I see now they are closer to 17k. Crazy. You might have to check with Facebook ecodiesel groups or ecodiesel forums to try and score that motor. I don’t suppose you can delete that truck in your location, can you?
I just double checked the website, and I see a new manifold kit is actually $662.22 plus tax and $20 for shipping. If that helps at all.
@tadsworkshop I'm in minnesota so I could no smog tests... it seems finding anywhere that does the programing is hard to find now... epa scared everyone underground
@tadsworkshop I have you saved so go ahead and delete I will definitely keep you in mind I was hopeing to do it with eztune or something simular as to not have to send the computer off
I’m currently getting ready to repair the leaking turbo coolant line on mine and I’m planning to do this as well, but I have been told two different things about the electric motor that rotate the swirl valves. Does the electric motor have to go back in place or can it be left off of the intake entirely? My truck is already deleted with stage 2 tune
Depends on the programming done by the tuner. They can choose whether or not to disable and stop monitoring of the swirl valve system. Before you commit to removing the motor, you could disconnect the plug for it and see how the computer system reacts. It is a large connector kind of by the driver side of the throttle body I believe. You may have to remove the throttle body as shown in another of my videos, to get access to that electrical connector,
@@tadsworkshop thanks I’ll reach out to my tuner. Mine isn’t completely apart yet, so I haven’t actually laid eyes on it and was concerned that removing the electric motor may leave an opening to somehow lose intake pressure. But if it’s just a tune adjustment I’ll be fine leaving it off if for nothing more than just having the extra clearance under the intake. Thanks again. Great video 👍
@@NOS-ZL1 nope, no boost leaks whatsoever with the motor and swirl valves removed as shown in this video. And it is definitely nice to free up room under the intake without the motor in place. The motor makes it that much more difficult to reinstall the manifold.
@@tadsworkshop just got done with my turbo coolant line repair and did remove the swirl valves and did In fact remove the motor to them with no issues with the tune. No check engine lights. And wow without that motor the intake just sits right down with no struggles. I appreciate the video I didn’t know it was an option to do this mod. New intake, all this swirl valves and motor deleted the truck seems to run smoother also a bit more pep to it and have gained a couple more mpg. Thanks again
@@NOS-ZL1 I appreciate it. Feels good to take care of all that, doesn’t it? Should help with longevity, mileage and power. And yes, installing that intake is a pain with that electrical motor in the way. Keep that truck going!
what if i broke a couple of those plastic little inserts holding the gaskets in place, you think it'll be alright without some of them ?
Your call. Think about how much pressure the inside of that manifold sees from the turbocharger, and bear that in mind. If in doubt, replace that manifold. You do not want to take it apart twice.
@@tadsworkshop yeah, idk. i kinda think it'll be alright. the first rod came out smooth. the second one hung up a lil, and before you knew it i saw plastic flying lol.
Como testar se está funcionando o motor ?
Hi. Do you work on these ecodiesel engines a lot? I’m looking for a mechanic that can work on my motor. Thank you!
I do, I’m located an hour north of Detroit, MI.
@@tadsworkshop I will be hitting you up for some work. Thank you so much!
@@Bekim8310 no, problem, just let me know. Whereabouts are you located at?
@@tadsworkshop Im in NY. Just outside NYC and there are no diesel mechanics out here. If I need service I take it to the dealer and I don't think they know much either. How can I get in touch with you? Thank you!
Hey i did this to my deleted ecodiesel and now i have an engine light on. p2022 & p2017. Any questions
Keep the two shaft position sensors plugged in on the intake manifold. And maybe keep your the swirl valve electrical motor plugged in as well, although you shouldn’t have to. If all else fails, the problem is the tune itself. Inquire to see if the intake runner/swirl valves being turned off are part of the tune.
Do you know anyone that can adjust my tune I’m having codes because I removed my swirl valves and my intake butterfly plate
@@adrianugalde5633 give me your phone number and I’ll call/text you with a solution.
@@tadsworkshop973-722-2070
I had my tuner adjust my tune and was able to get rid of most code but still have p04da
Never had this code after deleting until I took my intake manifold apart to fix coolant leak in valley
If I remove those valves am I going to get codes and I have a non tuned truck
All you can do is try. My opinion is, as long as the electrical actuator motor and position sensors stay in place, there is no way for the computer to know if the plastic valves themselves are in place. But, could this result in increased emissions which could set off a check engine light? Also another possibility. Experiment at your risk and expense of time.
Thanks for the fast reply man! At the moment I’m at a crossroads, my truck is out of warranty and I live the truck but right now I’m at the point where my intake is probably shot and it’s probably leaking like your client. I smell coolant in the engine bay at times
@@user-ep2ww2dn9t are you anywhere close to me, here in Michigan?
@@tadsworkshop I’m in Iowa haha kind of far from Michigan
@@user-ep2ww2dn9t yep that’s a bit of a hike. Do you have emissions testing there? I’m curious if a delete tune is an option for you.
what was the purpose of those?
It’s a way of managing air velocity into the combustion chamber, so as to reduce emissions, particularly at low speeds. Manufacturers need every advantage they can get to comply with emissions standards. These flaps have been in use since the 90s on a wide variety of electronically controlled engines.
My ecodiesel is deleted, do I even need the motor or swirl valves?
My eco is deleted and my check engine light came on this morning and it’s throwing code for IMRC. My question is if i do this then the IMRC is no longer needed correct?
@@robschmidt-yw9ht you do not need them. Consider replacing the manifold if yours is caked with soot from before the delete, and than remove them from the new manifold.
@@gemer069 you should talk with the source of that delete tune. It should have turned off the swirl valve system completely and eliminated any codes for it. But yes, you can remove them now that the truck is deleted.
