Intake Manifold Vac lines
Posted by Bob E. On 2017/10/14 19:37:13
Hi,
A couple of educational questions regarding the steel (vac) lines on the intake manifold. I assume this bottom 'nub' is vacuum although not connected to anything. Page 2 of the Engine chapter in the Service Manual shows a depiction of this "nub" as well. Is it meant for anything? As I re-assemble my engine I'm getting to know its intimate details and curious about what this is/was (it looks to be 'professionally' closed off).
Also, see the 2nd pic on the line that comes off the exhaust gas warming feature of the intake. My line is twisted, rusted, and doesn't look like it has a good seal. Do you know of a way to remove this without it breaking off so that I can replace it with a new line? The line twists when I try to loosen it.
Related question: I am going to paint the intake manifold the Hirsch Ivory. I'm guessing the paint will burn off this part of the manifold as it is gets as hot as exhaust gases and most 352s I see have this section discolored. I plan on using black exhaust pipe paint for these 2 areas unless someone has figured out a why to make the ivory withstand the heat.
As always, thank you for reading,
Bob
