will cleaning EGR + egr ports really give more MPG?

[90Haccord]

Will cleaning the EGR ports give more MPG or can i get away with just cleaning the EGR module ?

The ports look like a royal pain in the ass on a 1990(have to drill em out).

Car is way above what its rated to get(19/26 mpg rated), but it has 230K and EGR + ports have never been cleaned. I'm not getting an CODES on the ecu aka check engine light.


Wondering if all that trouble will be worth it, my ram air intake gave me an extra 2mpg and it was simple as hell.

What do you guys think?

Oh it will becasue it will remove all that booger in there. It gives cleaner emmisions too. Save Mother Nature

i would just pop the egr out and clean it it wont hurt anything and its not that hard to get out itmight help out with gas mile by maybe 1mpg depending on how dirty it is

[90Haccord]

how do you get to those 2 bolts on the EGR under the hood?

They are DIRECTLY under the egr so I cannot get my damn wrench on them straight. What i mean is, the EGR is on top, the bolts that attach it directly underneath and you cannot get the wrench straight on them, ideas?

what are you talking about? there are two 12mm nuts you remove in order to take off the EGR valve. they are easily accessible from the top.

[90Haccord]

No they aren't, I've tried. I'm using a socket wrench, tried super short extension and my 4" extension. I cannot get in there straight to get a grip on the washers. The washers line up with the edge of the EGR therefore, a direct line of operation is not possible. I cannot get a grip on the damn things

[Cb7GHOST]

ok so just to make sure, what are you trying to take off? the egr valve?

[90Haccord]

Yea just want to take off the EGR valve under the hood by the INTAKE to clean it? If it can be cleaned, hell I don't know, just trying to get more MPG and keep my car in good shape


I can take pictures if need be

[Cb7GHOST]

i just went out to my car and now i see what youre talking about. my tools seem to get only a little bit of an angle, but its possible to take off.

hmmm.....you might need that special socket with that joint swivel or whatever!

clean it with what?
brake cleaner
carb cleaner
engine cleaner
water and soap

I'm thinkin carb cleaner? or maybe that seafoam crap?

x's 2 on getting a swivel. You might also be able to get a box end wrench in there.
carb cleaner or brake cleaner work great.

[helofast]

dude doing it is easy, you just need to have patience and make sure you use the correct tools.

[92bently]

yup a chrome universal socket works wonders..but to clean it properly u will need to remove the intake manifold right??thats where the ports are for the vale, and thas what u want to clean...but yeh brake clean or carb cleaner will work

[goodybear]

I would like to clean my EGR ports as well. Have somebody post a DIY for this?. Or, at least somebody tell us where it is located. Thanks
