I have been chasing a vacuum problem. Found 2 likely culprits so I started a new thread.
1. BOTH plenum support columns at the top are leaky. I just tried soldering and then brazing, both did not work. I am reluctant to weld because of the gage of the material and the skill of the welder......grin 2. The control shaft in the Throttle Body is leaking as well, is there any way to fix this without milling and new sleeves inserted? Also, as luck would have it, my son cleaned and painted the unit PRIOR to me having time to test it........ Thank you, CTC911CTC  |

vacuum hose fitting for the aux air valve is pointing the wrong way
Have never seen the support tubes leaking before, if you are afraid of welding then epoxy they have some really good ones these days\ Tubes should be painted with Wurth zinc spray for the exact color and texture QUOTE(ctc911ctc @ Apr 15 2019, 01:35 PM)  I have been chasing a vacuum problem.
