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  |

Just a thought, but make sure you have or need to put the plastic bolt back on your accelerator stop. A common destroyer of plenums is not having the plastic bolt and flooring it a lot. Your plenum is compromised by the cable pulling the throttle open past where the throttle goes, tweaking the plenum.
Ask me how I know.... (IMG:style_emoticons/default/smile.gif) |
