I just cleaned the her valve I didn’t clean the ports, I never understood why the code kept coming back even though I replaced the egr valve. Thank you🙌🏽
I've pulled those EGR Port plugs on 2 different H22A4's inside the engine bays of 2 different 1999 Honda Prelude's. Getting those port plugs out is quite tedious and I split the I/M one of the 2 times. I didn't think it was necessary to split the I/M. during the second H22A4 egr port cleaning. Your video is good and definitely would be helpful to use if you've never done this job.
You should use gum out carb cleaner. You can put shop vac on egr mount plate, and beyond the plugs is a chamber, but below each plug is a 1/4 inch hole leading into intake that need to be gently reamed
When you drilled into the EGR ports, no debris landed in the manifold? also blowing air directly in there doesn't push all the build up in the manifold? What were the symptoms that your Prelude was having (aside from the code) that made you do all this? Thanks for the video!
The common trick is to have a vacuum in operation so as you're drilling it sucks up the metal shavings so they don't go in the manifold. Honda techs (I talked to one) use compressed air only for this job so if they're doing it it's good for me. Of course I also used 2 cans of carb cleaner and got is super clean. Between the air and cleaner I think I got most of it, maybe some got pushed into the abyss but I got most of it. The code is what led me to clean the EGR valve, but while I was in there I realized how dirty everything was which led me to do the EGR port plug carbon clean. Dealerships do it as a routine maintenance. It should be done on occasion, mine were very clogged. The car runs better.
@@joeKisonue That’s actually what I’m doing, had to pull the head off because the headgasket blew, while everything is off I’m gonna clean the intake and get a tap and die set
@@gabrielheard2287 nice and replace the valve guide seals. Mine used to smoke so bad after oil change on deceleration, I finally stopped doing oil changes. Just filter and add oil and Lucas
@@thatguy5339 i cleaned out my brothers 2000 prelude egr ports for California smog. Had it tested and passed for smog. After smog i put a block off plate for the egr valve. Basically a gasket that has no round or square part for the egr to flow. I did this because i dont want it to plug up with carbon again. We all know hondas burn oil. Lol. I dont care if the light comes back on. I will just take it back off when smog is due and clear the code and run monitor. I love California but hate the people that run it. Lol
I don't believe you because (1) Honda's EGR service does not include that step and (2) I cleaned out a ton of solid, caked-on debris....to suggest that that's not doing much isn't accurate. Those passages were fully clogged, it made a difference in the way the car ran and my mpg improved as well.

Thank you very much for this video. 👍
my mileage is ass so I definitely need to do this asap.
nice vid :D
Thank You so much :)

Where did you get the new egr plugs and part # please

Most of or all debris is coming up the drill bit flutes, and it's brass. It'll go right through
Where did you get your plugs, I can't find any still in stock on any sites so it looks like I'm gonna have to pull the whole manifold to clean it out
I do not remember, but alldiscountparts.com usually has everything.
Also yes if you are pulling the manifold tap all the holes and put threaded plugs for next cleaning

ever have issues with your atts sytem?
The light came on occasionally for apparently no reason. Part of the reason I moved on from this car, too much aging tech that's too pricey to repair.
Moved on to what a subaru sti
I need to find a good mechanic nobody don’t want to clean my egr ports
Put a block off plate and you will never have to do it again. Lol.
block off plate on what

@@gsr2envy ohh snap! i live in Tn so smog doesn't matter much i think, how would i go about getting a plate to block it off 😂
@@thatguy5339 they make fancy ones online ebay. But im cheap. Made my own out of tin can. Nothing special. Plus its hidden under the egr valve. Lol
@@gsr2envy is there any cons to doing this??
Unless you pull the intake manifold and clean them out you're really not doing much
