That's impressive!

Ok, I'm not going to question silicon over manifold gasket… as long as it holds.

But, what about the split between top and bottom? As far as I can tell there is a leak there, audible and visible via smoke, less than 6 months after the re-seal. Should I even attempt to do this again (or let the shop correct it)… or is this project doomed no matter what. I mean I don't want to do this every 6 months and hope it lasts longer.
