Posted July 30, 200915 yr comment_290705 I was planning to do the modification where you close off the passageways inside the BCDD on my 1978 280Z. Will this completely screw up the function of my EGR valve (since I have to pass smog), or will vacuum still be applied to that ported vacuum nipple? Thought I might ask here in advance before I started tearing into it. Link to comment https://www.classiczcars.com/forums/topic/32677-bcdd-vacuum-and-egr/ Share on other sites More sharing options...
