They are usually on the valve cover. Trace the hoses from the carb since they are vacum actuated. 1 of those should lead you right to it. If you shake it & there is movement inside, it is good.

The PCV Valve is located in the valve cover not the EGR. The EGR valve is located on a spacer block that is installed between the Carburetor and the Intake Manifold. It points to the back side of the engine behind the carb. The EGR will be visible once the air cleaner assembly is removed.
on engine manifold
There is none. The emissions are controlled with the PCM.
FUEL pressure, or possible egr valve malfunction.
EGR stands for "Exhaust Gas Recirculation". the 7.3 is a Diesel engine not a Gas engine. Diesel engines are not equipped with an EGR.
Invalid question. Ford starting putting the 6.0 in 2002. Therfore there is no 2003 7.3. So is your question about a 6.0 or a 7.3
Ford did not start putting egr valves on a diesel engine until late build 2003 when the 6.0l engine came out. Even the early build 2003 ford diesel trucks that still had the 7.3l did not have an egr valve. the only thing close on a 7.3l is the ebp sensor. and that measures the backpressure in the exhuast.
Should be located on the intake manifold.
Should be located on the intake manifold.
where do you find the bleeder valve on a Ford Diesel F-250 6.0
the egr valve is on the top front of the block and is easy accesable by your do it your self mechanic and the sensor is about 5 inches behind it
The EGR valve is located right behind the intake elbow that directs air coming from the intercooler (charged air cooler) into the intake manifold. The valve is between this elbow and the fuel and oil filter housings (black caps in top middle of engine).
Overheating and high boost pressure typically are signs of an EGR problem.
