Thanks a ton. Not a lot of DIY stuff out there for the D16Y5. Really helpful since this is a common problem with HX/VTEC-E. I wish I would have found out along time ago. I chased a CEL for about 10 years, and threw hundreds of dollars of parts at it. I haven't done the cleaning yet, but I'm 99.999% sure this is what's going on. Could have been fixed for the cost of some parts cleaner, and a bit of time. Really good job on the video too. I'm a parts changer, and feel comfortable doing this. Thank you.
My dad had his 96 serviced like this, by the local "Honda Guy" and soon after the engine started running really bad. He took it to the dealer and they found a short length of the file he used had broken off and made its way down into the valve on cylinder #2, holding it open. Damaged head, valve and piston, I think the sleeve/block was OK. I'm not saying don't do this but, be really damn careful people. If you drop anything (other than carbon dust) down in those holes you MUST pull the intake manifold. The more you know, right? Never the less this is a great video! Good Job!
+Wade Woodring yeah it seems more of a human error than the job error. You just gotta be careful of dropping anything down there like you said. I would've taken it back to the guy and have him redo the job since the problem wasn't there before. Glad you solved the problem though.
Had a random misfire on all cylinders. Didn't know about these passages until went to Honda for a diagnostic. Spent hours checking everything ! The ports were way more clogged than yours. Hope this gets around, Honda wanted $600 to clean and instal new EGR valve, it was o.k. Thanks for a good video.
Just to note, the HX (d16y5) is the only 6th gen single cam civic that has an EGR. The DX (d16y7) and EX (d16y8) don't have an EGR.. Thanks for the video
If you decide to do this, DO NOT use a file on the intake while it's still on the car. You don't want to have any metal shavings going into the engine. Do it correctly, take off the manifold.
I always use the oldschl method to clean this type if shit off...good ol' gasaline in a spray bottle...in a well and safe ventilated area that is....but hey gott give it up to the guy , a clean system is better than a dirty one all day long so good job bro...great to know for those D16 engines who do have an EGR valve.
Thanks, man. Great video, I have the same engine; Your video helped me a lot as I got the P0401 code. Sure enough, I followed your lead, and the 4 ports were fully clogged and caked up. I knew this must be the problem, and sure enough, after cleaning all the gunk out including that on the manifold over, code cleared!

Great video. My car is honda domani 1997, engine code D16A. I wonder if my engine have this EGR like that. Does anyone know? I noticed that my car don't have the EGR bottle on the left side just like in the video. But i noticed a bottle stated PCV. Is that have something to do with EGR?
The part he removed is the EGR chamber cover, correct? Not the valve cover? When I search up EGR valve cover gasket, it's a totally different shape than the part shown here.
I went to my local oreillys to go pick up a new gasket they have no clue what a "EGR gasket is" it only shows up with the valve gasket for the egr is there a specific name I could tell them? ive already tried "EGR chamber/ Gasket"
wow, I have a same car same color just like yours that was doing the cleaning today, really wish that I could see your video and it would have made things easier to remove, one thing that I need to say, you didn't clean the EGR valve which is probably very dirty just like the passages, some people are sharing egr valve for other hondas on youtube and I just saw it, I'll do the cleaning soon, if you don't mind sharing the video about clean egr valve, that'll be perfect, thanks again for sharing this great video
Did you ever figure out the problem. Currently having issues. I swapped mine and now has random misfire on all cylinders. Changed everything and still stumbles and misfires anything over 1/4 throttle
My '96 Civic won't start when the motor is warm. Has fuel, spark and compression. Timing belt replaced 5,000 miles ago. Could a clogged EGR valve be the problem?
I am curious, how delicate do you have to be when cleaning the EGR cover and the inside? Could you just use like a metal brush and brake cleaner for the EGR cover? Thx for the video!

Karina Cea during non AC operation, the AC compressor clutch isn’t engage, the pulley is free spinning on the drive belt so it doesn’t have any drag.

I have a honda crx 1989 hf its showing code 12 meaning (EGR) check engine light comes on after running my crx for 2 or 3 minutes on the road then start idling up and down like i have a performance cam in it🤣 not funny tho a lot of people say that that my motor dosent have EGR but i can see something that looks like one just next to the fuel rail a lot of people say to me its just the idle control valve but can someone help me with this please?by the way my crx has a d15b2
+Luis Montalvo - There is only 2 things you can do if you have EGR Problems / Codes.... #1- Clean it and put it back. #2- After cleaning and it's doing the same, REPLACE it!!!
I think they are called that too. I tried looking it up and could not find it though. I think I might have to go out there and talk to someone. Funny thing is I actually did this just a year ago with a new gasket and everything lol. Thanks for your help and for an awesome video :)
Yea that is true. I went ahead and used the old one. I tightened the bolts down to ten ft lbs. I think it did the trick but I still have a vacuum leak somewhere. I think it is either the PCV or the IAC at this point. I worked hard at redoing the exhaust manifold gasket and the intake egr passages. Would a leak after the catalytic converter and o2 sensor affect stft and ltft?
@@NutzAboutBolts would it damage something if one were to flood those holes with carb or brake cleaner? (and then start the car without trying to remove the cleaner) I guess it would just go into your motor and cause a temporary rich condition, right? Could something like that damage a catalytic converter? (maybe this is a silly question. I don't know much about cars, just very basic stuff.)
James Chuaycham ป้อม ศักดิ์ชัย I'd that's the egr code this should fix the problem if the code still comes up after you have done this then you need to replace the egr, I have a 98 hx with this problem, I replaced the egr and still have the code so this video here should fix my problem for sure, I really need to pass inspection lol
Not always true. On a lean-burn model such as VX or HX, the EGR is extremely important to getting good MPG. The lean combustion is fairly delicate and without the EGR, the car will add more fuel correct the higher flame temps.

Could this blockage cause poor acceleration?
The egr passages he's referring to are in the egr chamber. You can buy a new egr chamber gasket.

When turning on the AC why does my engine loses power? Like it decelerates below 0, I have a 99 Honda Civic EX
Because it requires engine power to turn the ac compressor.
NutzAboutBolts could you explain further
Karina Cea during non AC operation, the AC compressor clutch isn’t engage, the pulley is free spinning on the drive belt so it doesn’t have any drag. When AC is operating, the AC compressor clutch is engaged and causes the drive belt to have a drag, which causes engine to work harder to spin the AC compressor.

You may or may not have the same engine as what is shown in the video.
Here are a couple of ways to figure out exactly which motor you have:
Look for a code that is physically stamped on the engine block (or maybe on the cylinder head?... I'm not certain.) My car is similar to yours (1999 civic hx) and I can find my engine code to the left of and under the heat-shield for the exhaust manifold. It's in a pretty obvious spot on my car, maybe yours is similar?
You can also use your VIN to figure out which motor the car came with (originally). It is reasonably easy to find the factory service manual for these cars online and the first 30-40 pages are all about how to "read" the vin. (Make sure you look at the right page though. There are separate pages for each model year and body style. There's also a difference between VINs for cars sold in the US and cars sold in Canada)
