There's a flange near my throttle body. If you're standing at the left headlight and look into the inlet of the throttle, it's to the right hand side, pointed at the firewall at about a 45 degree angle (towards the driver area). It's a two bolt flange and looks to be for an EGR valve.

It has a block off plate on it.

Has someone tampered with my emissions systems?

 

Only a California emissions 10 cyl should have an egr valve.

 

Egr valve? What's that? Never seen one on a V10 b4.

 

Interesting, my EX doesn't have any sticker under the hood indicating that it is a Cali compliant vehicle but I did need to get the Cali fuel pump when my pump died and it also has the after cat O2 sensor but no EGR valve. Seems strange but my ride was originally a government truck for the Army Corps of Engineers, maybe Uncle Sam had some crazy combination of features required for their rigs back then.

Yeah, the Cali fuel pump is different, it has the tank pressure sensor while the 49 state model doesn't.


Terrible picture but that is the after cat O2 sensor.


And this is my factory driver's side exhaust manifold, if it had an EGR valve it would have the port for it machined into that raised circular boss that is blank here. Pele if your manifold looks like this, you didn't have a valve, I haven't looked at my intake for the block off plate you described but it makes sense so Ford only needed one version for both options.



Dave, I haven't seen one either, of course I live pretty far away from Kalifornia. But when I ordered my Banks headers I had to choose between V-10 tubes with or without an EGR provision so I have to assume that some SuperDuty family members had the valve.
