So everything I'm seeing is either referring to a v6 configuration, or a 1990-1993 vehicle.

Does anyone have any information on cleaning the EGR valve and ports for a 2003 4cyl?

I'd imagine it's fairly similar, but I wanted more confidence in the procedure before I started.

Thanks!

 

2003 4-cyl engine is WAY DIFFERENT from the 90-2002 F-series 4-cyl.

Look for EGR instructions about 2003-2012 4-cyl engine. In general principle it's the same, but components are in different locations, etc.

 

Man, my google-fu must be off.. The best I'm finding is how to replace the EGR valve, which is mostly common sense.

In the case of cleaning, do I just clean the valve's holes, or are there ports I still need to clean?

Not finding much in the way of information... A lil help would be appreciated!

Thanks!


**EDIT**

You'd think that something that gets clogged so easily, it'd be easily accessible, and wouldn't require drilling/tapping/slide pulling...

BTW, this is the best write-up I've found: http://home.comcast.net/~em-engineering/T2T013.pdf

I realize the locations might be different, but want to know if the process is similar. If possible, I'll document the process while I'm doing it to get a more up-to-date document going.
Just wanna make sure (and I don't have the car right now to look) if the ports are similar.

 

Another question... has anyone tried doing something like epoxying a small screw to the top of it to allow for easier removal later?

I'm not necessarily thinking tapping the plug, but just epoxying a screw on top of the plug.. is there enough clearance?

 

*Bump*

Still searching around for information...

Would I just clean the EGR Valve and call it a day? OR are there EGR runner ports that need cleaned too? Are they under the intake manifold?

Seriously not finding any information for an 03 i4. Help would be appreciated!

 

Wish I could be more help, but I never had to do that while we owned the 2003. There has to be passageways inside the intake manifold, that are connected to the EGR valve.

I don't know whether those passageways are a complicated "network" or just a simple tunnel that you can clean out with carb-cleaner & a toothbrush. I suspect the carbon plugging was already a well-known problem when they designed the K-series engine. Hope that they made the passageways big & easy to clean.

 

Well, I wanted to do more than just clean the EGR valve... but looks like until I find more information, I guess that's all I can do... Don't wanna take the intake manifold off to find out it's not serviceable.

 

I saw this old thread and wondered how the EGR work went. I'm getting the EGR code on my '03 LX I4 and have the same questions about whether an EGR valve cleaning will be enough or whether I need to go rooting around in the mainifold.
