Keith Browning Posted June 29, 2005 Share Posted June 29, 2005 I got a tip from the Hot Line that worked. Actually, the diesel team seems to have it together for the most part. Anyway, When replacing an EGR valve and you discover heavy carbon has built up try using the injector sleeve brush from the 7.3L kit and a vacuum. The brush part number is 014-00934-5 and I use a Snap-On pneumatic vacuum, tool number YA 254 (Blue Point) It actually worked well in breaking up that carbon in the ports and getting it all out. There have been concerns that some of that carbon has broken off causing repeat EGR problems. Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted July 23, 2005 Author Share Posted July 23, 2005 I just completed an article "EGR Servicing" with some good photographs showing the carbon problem and cleaning the ports. You might even find the diagnostic tip helpful. I am interested in any comments/criticism or additional thoughts you might have. Don't be shy!

AMCTech Posted July 29, 2005 Share Posted July 29, 2005 Good point, Keith. The subject of coked egr's and ports was discussed at the Fordstar roundtable wednesday. I've used the 7.3 bore brush with success, and have a blue-point brush from an old 9.0 IH service kit that works great also. One of the service engineers went so far to suggest intake removal if necessary, which I had to do last week with the worst case I've ever seen on an 04 450. The egr, orifice/bore, the whole mess was one solid block of carbon black. Mess. BTW, it was also said that an improved service replacement egr would be available early next month. Hope so!!!
