Re: 2007 Lincoln Navigator EGR Valve location
The 3-valve Triton motors (2006+ for the Navigators...) use variable valve timing to accomplish what the old EGR valve systems did. So there's no physical EGR valve to see on the motor. Ask the emissions testers what they do for the other 3V Triton motored vehicles they test. (i.e. 2004+ Fords and 2006+ Lincolns...).
