EGR Valve Replacement and Experience
Hello everyone,
My truck as been running sluggish for the last two weeks, and exhibited sluggish take offs with black smoke coming out of the exhaust, and just lacked the power it typically had.
The sluggish take offs with black smoke and delayed turbo boost was the tall tale sign the EGR valve was blocked with soot. So I purchased a new one so I could clean the old one and save it as a spare. The removal process using a small crow bar is the ticket to remove one of these and the complete job took about 30 minutes and the EGR cost $190.
The difference in performance is really great!

The build up of soot is such a slow process you really don't notice how the performance deteriates until I installed the clean/new valve.
Overall the soot that made contact on the valve and inside the manifold was slightly greasy and the soot that was suspended in the valve was dry and fell out.
I never cleaned an EGR valve and reused it, but at this point with the performance with the new EGR valve, I highly recommend performing a yearly PM and clean the EGR valve and replace with new orings.
Also I can't help for thinking with a partial to blocked EGR valve if that is blocking exhaust flow into the manifold therefore causing the same soot build up in the EGR cooling????

How come today on my '05 I disconnect the EGR and the scan gauge reads 100% open?
I did it key on/ key off and running. It still reads 100.Am I reading the gauge wrong ? I think 0 is closed and 100 open ?
Ford Truck Enthusiast....yeah thats original

I used to monitor EGR%, and you are correct that 0% is closed. The highest I ever saw was something like 30% IIRC, and my thought was that it was showing the percent of exhaust flow versus charge air flow, and not percent of valve travel. I certainly never saw 100%, but then I never tried unplugging the valve either. I don't believe 100% would ever be a valid feedback from a functional valve.
