Question about Cars & Trucks
Check if the oil is coming from somewhere else. There is no oil or oil passages at the egr valve. The vacuum diaphragm is a ported vacuum signal (from just below the throttle valve, ported vacuum means it only gets vacuum when the throttle plate is opened by the gas pedal-like off idle). The valve is mounted in the intake manifold, and the exhaust gas reaches the valve from a pipe from the exhaust manifold. There just is no oil around the egr valve.

Just an idea but the Ford Mondeo ( european car ) from which I believe your engine
is taken has a habit of splitting a low pressure tube at the back
of the engine this is a relatively
cheap, easy fix. The other symptom this used to throw up was a
little more black smoke from the exhaust and a pacing/ surging from

If you are sure the valve is working and the passage is clear....it should stall the engine when you put vacuum to it while idling, then you may have a bad MAP sensor. There was a problem with them on this year. Sorry, I don't have the specs for the modulator with me, I'll try and dig up some info later today. The reason I said MAP sensor; the computer uses the signal from the MAP when it runs the diagnostic to check EGR operation. I'll add to this solution later today, in the meantime, does applying vacuum to the EGR stall the engine? If not, you'll need to remove it and clean out the intake manifold.
