I don't have a spare plenum to use to find out where the EGR ports run, but from memory I think it makes a loop inside the plenum and back around to the EGR valve with an internal passage. If my memory is correct you'll have a tough time trying to rod it out. Maybe someone else has a spare plenum and can check it for you.

If your engine needs $5000 worth of work, you need to send it to me for an overhaul. <img src="/forums/images/graemlins/lol.gif" alt="" /> That sounds quite high.
