ENG: EGR Port Cleaning

[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.

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.

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

[92acclude]

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 in the world should i do?

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.

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]

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

What now?

[b3nsonx]

ok im sorta confused. the link only says the 90 cb guys need to drill, but everyone posting is talking about drilling. i know that not everyone has a 90. so if i have a 91, what am i supposed to do?

[93SM4_CB7]

how much would a shop charge to do something like this .. i would love to do this but never really done anything as far as motor work before..

spshhh.. i tried taking off the freaking IACV and couldnt even get that off.. freaking screws just started to strip

[gloryaccordy]

Good shit, prob gonna try this this weekend. Got the dreaded code 12

[F22HB]

I can do this for people who are super concerned but you'd have to ship me a set of runners so I doubt anyone would want to do it this way. Offer is out there though. I've done this on 4 diff intakes now,lol.
Here is blue plugs...


And silver...

And more silver...

lol

[accordztech]

gee i dont even remember using a slide hammer to do mine. i think i drilled it and then let it grab and either pulled or something.
