It is the EBV control. I have deleted it on my F350 and E350. On the van I plugged the control back in to the wiring harness and zip tied it out of the way. If not, it will leave a soft code in the computer. (no check engine light) Then I gutted the EBV valve out. While I was in that part, I used a die grinder and smoothed out the inside of the valve housing. I used this non ebv turbo pedestal: http://www.strictlydiesel.com/p-2660-non-ebv-turbo-pedestal-late-99.aspx
My oil leak was the non serviceable hpop plug. This guy sells one to replace it: http://www.dieselorings.com/serviceable-replacement-hpop-plug.html
