The vid does use hylomar there and according to other builder friends of mine that don't use it but say you technically could. I think it is a safer then sorry type of thing. The sealant is only used there to confirm imperfections in the metal seal.
In my practice I do not feel comfortable sealing it with a gelitan tack that never cures and does wear and or burn away. This makes me feel uncomfortable to send the motor to a customer when I could of used a cured sealant properly and be more asured.

I'll be stacking a rebuild here in the next couple weeks and I'm wondering about the lower leg sections of the housings. Most people use RTV (copper or black), but I'm wondering why I couldn't use Hylomar on these sections. I've read the specs on Hylomar and its pretty high temp and is perfect for close fitting areas. Its also self-healing.. so if a gap DID occur from vibration, it would close the gap and prevent leakage.. (in theory).
Just an idea... has anyone played with this?
Up until more recently when Hylomar became more difficult to attain, I used it in said manner for several years and never thought twice about it. It seemed to work just fine for me, and I've built alot of motors in that time frame.

A Chevy dealership wrench clued me in to Right Stuff sealant. It's what you use if you don't want it to leak, period.

Hylomar is difficult to attain?
Permatex® Hylomar® Aerosol High-Temp Gasket Dressing
The original non-hardening, high temperature sealant designed for Rolls Royce. Ideal for threaded fittings where locking is not desired. Temperature range -65˚F to 600˚F (-54˚C to 315˚C). Gas and shop fluid resistant. Sensor safe. LEVEL 1. Suggested applications: Use on paper, cork, asbestos, metal and other preformed, cut gaskets.
Might not be the best choice for the housings, but it is used by everyone pulling gear boxes apart between sessions.
I use 100% GE silicone tub and tile caulk. Also used instead of an exhaust flange gasket.
