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

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

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....

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...

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.

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.

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.
