how to clean egr ports on a 4th gen h22a1 welded type

Ive searched and found nothing on the egr ports for the obd1 intake manifold so i decided to make my own and possibly help people like me.

first im not responsible for you destroying your intake manifold this job is easy but can take a turn for the worst because of not paying attention and just plain stupidity i wish i don't have to say this but when drilling these ports when you feel it go through stop!!!!! or u risk damage to your manifold also cover all holes with a rag or tape don't matter just cover them form the debris that will be present when you use a grinder to remove the welds to get to the ports..

ok first thing i did was remove the fuel pressure regulator,iacv,air intake,egr,fuel rail be careful on this step not to get any debris in the fuel system cover everything also i recommended u replace all the little washers and o rings on the injectors or you can reuse them if they are reusable i mean this if there still rubbery and not cracking when u bend them then there reusable.i used a 90 d angled die grinder with a sandpaper pad to remove the weld ..just take it down far enough to see the out line of the plug u can see by some of the pictures then u drill through them with a 1/8 inch bit or whatever u have just nothing bigger then a 1/2inch also while drilling use some grease im talking like chassis lube on the bit so it caches the shavings after u get all the plugs out u will see some of the port holes have a little 1/8inch hole inside these are the egr port holes there are 4 total they are the reason your doing this job so clean them the best u can i used throttle body cleaner and a little injector cleaner brush from snap-on i have a good set of tool because i am a mechanic if you don't have access to snap-on them hit up sears or tool king they with probably have something for u to preform this job i also seen some people use some home made stuff do some searching and u will find them.also i used some brass pipe plugs to plug the port hole instead of the Honda ones because i want easier access to them later but if u want to use the Honda ones the part # is 17199-pt3-ahm or u can get the kit witch is 07waz-001000a but that's expensive.after using the brass plugs i used some epoxy (see last pic) to make them air tight put everything back together and u will see a huge difference remember obd1 h22 engines will not code for this problem but u will fail emissions hope this helps anyone.thanks for reading also any things u guys want to add please feel free

Good walkthrough, I agree. I'm gonna make a walkthrough on how to block off the EGR without a chipped ECU to avoid CELs. Nice job again man.

Have any of you tried Deep Creep? Instead of tearing the EGR track apart.

deep creep sounds like a game I used to play with my ex.

Re: how to clean egr ports on a 4th gen h22a1 welded type

hey I just looked at mine, they look like they have weld marks. Does this mean someone has done the EGR port cleaning before? or is that how stock ports come. I have an h23 btw
