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  |

Brazing is fine but might be easier to buy a known good one. The shaft needs to be redrilled with new bushings. The bushings are self lubricating and will be installed "in line" when done correctly. If that shaft were to bind when wide open you might be in for "the ride of your life".
I prefer the silicone rubber for those runners but you usually need to buy a 3' length at a diesel shop and it ain't cheap. It does take heat well and will out last the OEM sleeve. |
