99 D16y8 IM on 96 D16y8 head
Okay I just put in a 96 D16y8 engine on my 99 civic. I noticed that my Intake manifold has the air injection holes because it had a huge vacuum leak. I was wondering if I can plug up the 5 holes. And if I do what do I do with the FIA control valve? Do i just leave it connected. Also will this affect smog? What are the downsides on plugging the holes?
