Hmm, I saw you pics. They are lil bit blurred but I can see where your prob is. Esp the last pic:
EGR Valve. Your EGR Filter and that oil on the bottom. The EGR system can't leak itself. The EGR system contains valves, vacuum hoses and sensors. Did you know, that the EGR system is designed to reducing oxides of nitrogen emissions by recirculating exhaust gas thru the EGR valve and the intake manifold into the combustion chambers. It's composed of the EGR Valve, CVC Valve, EGR Solenoid Valve, ECU and various sensors. All functions are controlled by the ECU.
Example: If there is an error inside your EGR system, a blinking code appears in the Check Engine Light. Most likely code 12.
In other words: There is no place where oil is leaking or might leak. Know what I mean? The EGR valve itself contains a gasket, but it makes no sense to replace that. Probably your problem is that, what JetDoc said: Oil squirts somewhere out - maybe the valve cover seal? Did you check that? -Mike
BTW: Is that normal that MSN work sooo slowly? I have TDSL with 1536 KBit/s. But to open some pics needs to get a coffee
