EGR Valve Cleaned at 20K Miles

[ClarkSJ]

I bought my '07 F250 used with 15K miles on it last summer. Today I removed and cleaned the EGR valve at about 20K miles. Bought a kit off eBay that included the o-rings, gasket, cleaners, and Ford TSBs, from this seller:

Valve was almost fully plugged in one area, and it took some work to clean it up. But relatively easy to remove and reinstall. Also cleaned out the opening in the manifold where the valve sits, it had some carbon buildup (vacuum and wipe with a rag dipped in carb cleaner). I'll make this a 20K PM going forward.

And now, some "before" and "after" pics:

wow if yours was that dirty at 20k i dont want to think about mine at 50k. i better get that thing off and cleaned.

Nice job. Now just delete it when you can.

Probably won't do a delete, as I'm in California. But maybe a Bulletproof Diesel upgrade some day.

The same eBay seller has rebuilt EGR valves for about $70. To minimize downtime I may buy a second valve to swap in, then clean the dirty valve at my leisure. The swap is about a 15 minute job, including cleaning the manifold.

EGR bypass or EGR Delete?

Holy crap.i know what i am doing on my days off.i have 32K on mine.you did a great job cleaning it it looks brand new.

It cleans up fine using the technique in the Ford TSB-- soak in Ford carb cleaner, brush with a soft bristle brush (old toothbrush), rinse with Ford fuel injector cleaner, blow with compressed air. I used a toothpick to scrub the small areas that the brush could not reach, and also to hold the valve open to soak and then brush the plunger and seats. It's a messy job, but not too bad considering how it looks when you pull it out.

I have no idea how the truck was driven prior to my buying it. At 15K it had 480 hours on the engine. I doubt it was driven hard, but even so that is a lot of buildup for not a lot of miles.
