Tangential port #6
I pulled my intake last weekend with 97k miles as I think it's time for the first CBU cleaning. Attached are a few pictures of how the swirl ports and intake manifold look. While all intake ports have moderate CBU, the tangential port on cylinder 6 stayed completely clean! I talked to Lee4him and with his car it was the same phenomenon. I'd like to get your ideas as to why that could be. And don't go for the easy one - the swirl flap of cyl 6 is working fine.
