Hey my little darlings, I need to steal some brilliance from ya. I have a 78 FJ40 2F. I have a vacuum leak where the MC goes into the brake booster (my brake booster has that small little notch right above the plate where the two meet and you can feel the leak right there). I'm fairly certain it is just going to be a gasket/seal that's old, but my plan is to redo the majority of the brake system at the same time. With that, it is going to take me just a little bit to get the funds and parts together so I am looking to see if there is something I can use to seal that leak temporarily so I have brake assist. I have seen some guys post about using silicone or weld but I'm brand new to tearing apart trucks so I am not sure what is fine to use and what is just dumb. So - any help - I would appreciate ya for.
