[accordzoom]

great pics...

[accordztech]

its weird. people done this and had good experiance...they took out the 4 holes...but mine has 6....they are all the EGR ports and it has one access port on the side....

im going to be doing this within the next week...so imma try my theroy and open all the holes up....see what i uncover.

[xplode]

i think that in general there might be 4-6 ports. depending on what part came from where.. doesnt matter.. aslong as it gets cleaned it should be good.

[accordztech]

all have 6 ports and 1 access port except 1990. imma take em all out...maybe ill discover some gold

i went to the dealer today to buy some new port covers and they arent the same. instread of a flush mount like in the pictures, it is a hole inside like the inside of a pen cap. i dont like it. it looks ugly. they claim it is OEM but im like mine is OEM and mine is solid and nice.

[fenderltd]

so after you drill them etc. you just leave the drill holes open? lol its late, I need to actually look at my shit first!

[accordztech]

no u drill a hole, pull it out

clean

then put it back in or get new ones and hammer it back in.

[cp[mike]]

how bout u thread the top bit of the holes, and get a really short bolt and screw bolts into all of the EGR ports. == easy removal for recleaning down the road.

[xplode]

umm. no you dont do that.. you just do it normal with new plugs.

[accordztech]

u can actually do that to help you later, but it may look funny. but its smart. you have to do it with the OEM plugs though not the new ones tthat come from honda cause theirs are a differnt sytle and cant mount any threaded posts to it =/

[DaveZ]

Hello. Does anyone have the Honda OEM part number for the EGR port plugs? Majestic Honda didn't know what I was talking about. Thanks.

[accordztech]

17199-pt3-ahm

its a egr port cover, service port. tell them they are dumb.

[DaveZ]

Thanks a bunch. I just ordered the parts from Majestic. Take care.

[arrozburner]

the link doesnt work anymore...how do i clean my egr valve?

[460sx]

It works for me..

I'd use pipe plugs instead, prolly seal better.

[HondaFan81]

So my 90 EX - F22a4 has bosses instead of OEM plugs for these EGR ports?

I haven't bothered to take a look. This could be something else to add to my cam timing project list....ugh

[Weezo182]

I need to do that honda is wanting to charge me $170 to do it... im going to try and get it done in my auto tech class ill have all the nice tools ill need and a few friends and teacher to help..... thanks

[Weezo182]

well i got one plug out and cleaned some what i am going to finish next week... most my time (2hours) were spend clearing space in the engine bay and getting the right sized drill bit and extractor.... and a tip: make sure you have a magnet close incase you drill to get the shards away and out of the port....

[FDAccord]

What type of difference would you notice when you clean it?

[accordztech]

depending how fuked up it is i noticed a bit of performance increase....but iono hard to say cause i swaped manifolds at the same time.

[Weezo182]

ya i felt a nice performance diffrence and a few more MPG....

[Weezo182]

A little warning... do not attemp unless you have the right tools or you will be wasting a few days getting it done with diffrent taps and pulleys it sucked... (Honda wouldnt sell me the right tool) if any one has one let me know mabee i can buy it off of you...

[91accord4door]

all i used was a $7 slide hammer and a screw to pull my pluggs out and its easy. you can find the slide hammer at any home depot or automotive store. i dont know why people dread doing this so much i actually enjoy it. its just time consuming not hard at all. if its done right you should have no problems at all.i have done 5 jobs already and have taking no longer than 1 hour 45 mins on each.and everytime has been a successs...........plus money in my pocket.:)

[tommi]

so what exactly is this im cleaning out like oil dust or what?


COLBALT CB7 2NER

[Weezo182]

carbon build up restricting air flow

[accordztech]

yeah it clears out those ports.

i forgot when or how but the exaust is re routed back into the intake manifold...through those ports....

if the ports are clogged then you loose power etc. oh and u wont pass smog.

[VRDrvr]

Its rerouted through the EGR or exhaust gas recirculation unit. The EGR was designed to lower the combustion temperatures by recirculating exhaust gasses back into the combustion chamber.

[Genki]

how much do the new plugs cost? I might do this..

[91accord4door]

6 pluggs i paid about $5 for mine. depends on your dealer. but they are very cheap.

[accordztech]

40 cents each most of the time for me.

give them that part reference number in the PDF file we put up.

sometimes they cant find it so that part number will help

[Genki]

Nice! I can afford this! :D

[Weezo182]

40 cents each for you wow i only paid 25cents each heh....

[LX Rida]

where can i get plugs. i plain on cleaning out my egr ports when i get my a6 manifold.

[accordztech]

noob HONDA DUHHH HONDUHHH

[wed3k]

okay, so for a 90 i would have to drill holes?

correct? i think i need to do this soon, chuggy acceleration, bad mpg.

[Alex EX]

can you drill them on the f20a?

[wed3k]

this is very odd, but i looked on my intake manifold and i DO have holes, 6 of em...

looks like i can do em after all. :yay:

[Alex EX]

i cant do mine, they look like the metal on the top is all molten.. im afraid to drill it

[91AccordLX]

so hey guys, my manifold has 6 plugs on it...do iu have to remove all 6 plugs or what? thanks

[wed3k]

i dont see why not, i mean...you are already there, lol.

might as well clean all of em out.

[91AccordLX]

well i didnt know if all 6 of them were ports...but i guess they are so im gonna tackle this project on monday..it looks like all i need is a slide hammer and a drill..right?

[wed3k]

yes, sir.

[starchland]

is it easier to take off the throttle body to clean it more thoroughly, i just dont want to risk getting metal shavings in my engine after drilling those plugs out.

[91AccordLX]

yeah but its not easy to take the TB off....

[starchland]

how did everyone avoid getting shavings in the hole?

[bodiez]

ahahahahha My local honda dealer wants $25 DOLLARS USD NOT CANADIAN for the plugs. GTFO. I couldnt find them on majestic, can someone please help me? TIA.

[wed3k]

http://www.slhondaparts.com/search.asp?partNo=17199

should say 20 cents a pop

[bodiez]

Thanks alot. Also my dad was wondering, can cleaning it make it worse? For instance, breaking up the carbon and it falling where it shouldnt. I hope you get my drift here.

i actually wouldnt really know, if they tell you to clean it out with a wire brush and spray with carb/brake cleaner, im assuming it'll fall itno the manifold anyways...

[cokinut]

i cant do mine, they look like the metal on the top is all molten.. im afraid to drill it

yea you can. just drill it! i did. after you're done cleaning it out, plug it up with some quick hardening epoxy "quick steel" or some jb weld.

here's a pic of my crappy job.

Crappy job is right. Get the plugs from the dealer and do it right. What you have it something that will leak down the road. :eyebrow:

And for everyone’s information, I'm the one who's hosting this tech article. :wavey:

[Nataku]

OK, I tired this and I can't get the screws to take to the metal, they either just keep spinning or break the threads off the screw. I've afraid to drill all the way through because of the shavings. any ideas?

[starchland]

are you drilling a small pilot hole first?

[Nataku]

are you drilling a small pilot hole first?
Yes, Sorry I forgot to mention that.

[xaxis360]

i know this post is old but nodody has really covered the whole issue about spraying carb. cleaner inside those holes to clean them. Where does the crap fall into? Does it get sucked back into the engine?

A Honda SB recommends vacuuming it all back out through the hole. Any suggestions?

[accordztech]

yea it goes into the intake system....but later burned off by the combustion process...

u can vacumn it out but there will be some that falls down anyways...

id try to vacumn some out and then the stuff thats in there, spray cleaner through the throttle body and then revv the shit out of it to get everything out and nice and clear

[uslspct]

Since this thred is up again, and I'm gonna do this this week, where the FUCK did you guys find a slide hammer? I tried every auto parts store without luck.
I'll try Home Depot or Lowes tomorrow but I don't think they'll have it.

[uslspct]

That kit is $160. I still need a freaking slide hammer. Someone lend me theirs or tell me where to get one.

[Final 204]

well i did my EGR's

did all 6, and used a vaccume, throttle body cleaner, slide hammer and various other things,

i noticed maybe a tad of a difference, i was hopping for more of a noticable result, but i think my car is idling better and i'm glad i did it.

[JaK FRoSTWhiTE]

Hey, uslspct i can help you do your plugs. I will try and do mine
on Saturday to see how it goes. Then we can do them on your car.
Imma try to get everything ;)

[uslspct]

I did em on Sunday. Didn't notice much difference. Let's see if my gas mileage gets a little better.
I actually found a slide hammer at pepboys, they had 2. But the screws that come with them are garbage.
Actually, I have had my check engine light come on and the car's idle go funky. I did 3 of the plugs. No problem. Then 2 more the next day and the problems start. It could just be all that carbon crap that got kicked out. Maybe messed with the O2 sensor, which needs replacing anyways. But then again it came back today out of nowhere. I hope it goes away or I have more troubleshooting to do.

And also, what about that one plug, that's not on one of the runners, but the other spot. It's right under a metal part of the manifold that holds the fpr. How'd you guys reach that one, all crooked?

[JaK FRoSTWhiTE]

And also, what about that one plug, that's not on one of the runners, but the other spot. It's right under a metal part of the manifold that holds the fpr. How'd you guys reach that one, all crooked?For that one u have to go in a little crooked.
Thats what i did. It worked out great. I did mine today at work with
Adam (Fast93Accord) did all 6 of them in less than 35 minutes. Hes the best :tu:
Any other questions let me know.

[uslspct]

No more check engine light for me. But I'm pretty sure I don't feel a difference in revving or gas mileage from doing this. They did have carbon in them though. Can't wait to do it on an A6 manifold swap with it off the car.

17199-pt3-ahm

its a egr port cover, service port. tell them they are dumb.

under what sections are these in? i went to the intake mani at majestics and can't find theM??

or do i have to manuall request it? i need 4 right?
and is there any other way to do it w/o a slide hammer?

EGR Port Plugs :: 17199-PT3-AHM
No, you need a slide hammer. Its just easier.
Go to Honda and get them, total will be around 2 bucks.

[FishyMan]

shoots i guess i'll pick em up locally though i hope i dont get raped already. i need some hondabond anyways.

so i need 4? or will it be in a complete set already?

[JaK FRoSTWhiTE]

I bought 6 plugs i think they are .28 cents per...

[alb_accord]

well i had a real problem on finding the right screw for the drill bit lmao..
#1 egr port was so fucked up... i was cleaning it out and was wondering how come there was no hole in it as it was in the other egr ports... then i just hit the middle of it with a small screw driveer and wow... there was a whole in it tooo. i still cann't belive i drove my car with a complete cloged up egr port.

[reidc]

OK- MY EX can't be different from everyone else's?

I got a 92EX Coupe(originally from California). I have checked out the pics in the original link, as well as some others- and the locations of my ports are actually closer to the throttle body!!! In fact- out of the 6 ports- it looks like I can get to one- maybe two(closest to EGR valve), but the others are pretty much tucked under the throttle body.

How difficult is it to remove?

My car needs the ports cleaned badly. I had a used distributor put in after a fail to start, and it SEEMS as though I began to notice the sluggishness and hesitation then. However- I disconnected the vacuum line and plugged it and car ran great.

There's gotta be a way to get at these plugs without removing TB. OH- I got the replacement plugs already, and as others have mentioned- they are not solid metal- just appear to be hollow shells.

I have done this procedure before on my 91 EX. I have a 90 now with a JDM F22B and the spots where the plugs are SUPPOSED to be look plastered over or something.... Is this the way JDM's are? I know they scrap the Blocks after 50,000 miles so why do this type of maintainance, but i'm curious to know if anybody elses JDM's are like this??? And also WHAT :confused: in the world should i do?

[mrvinyl33]

From what it says here atleast for USDM 1990 only they didn't have removalable plugs and had to be drilled and I guess filled afer the service was done.

http://home.comcast.net/~em-engineering/T2T013.pdf

[RustBucket93]

I tried to do this a while back, but had problems removing the fuel rail to get access to the ports. I couldnt get the connectors off the injectors, and they kept popping out of the rail.

What all needs to be taken off for a 93? Do i disconnect the fuel lines on the fuel rail too?

OH and I remember there was some bolt that I was unable to get a socket on due to another part being in the way. I'll check it out tomorrow.

[colslaw87]

Excuse me but...how is this procedure going to make any difference?, it doesn't seem like your doing a whole lot.

I have a jdm h22 and I have the same thing. I looks like the welded the ports shut. What is this? Why? Can I still clean them, or do I reach them from inside the manifold? Help people.

[accordztech]

i wonder if u can drill it out and just weld one back in...

better yet get the usdm edition which maybe the same (not sure) and just use their bottom end...and use the JDM top end.

[lonski]

I need to clean my egr ports as well, but I don't wanna take the whole IM out. My question is, if dirt from cleaning the egr ports falls through the runners, will they do any harm to the engine?

[PR CB7]

eeeeeeeeehhhhhhhh

yeah!!!!!!

[SuperTuner12010]

About the threading the ports...I saw I dont know were possibly here but they threated the holes and put alan set screws in there...

They sat flush and looked great...

[F22HB]

Why does everyone say that the shavings and what not fall into the intake runners? The egr is seperate from the intake runners, so..... someone enlighten me please?
Edit: nevermind, I'm a noob.

[helofast]

http://i67.photobucket.com/albums/h318/helofast/Jul18_0001.jpg

I drilled the holes but the screws thread keeps f**king up everytime I try to pull the plug out.

What now?
