I always hated using a tube of silicone to make a gasket

Don't know if this helps but it looks like it might work.

Interesting - sewing thread.

We use other kit for these engines, Drei Bond 1209, this is OEM.
And the engine you see in the video, has negative cranck pressure, so as long as it runs, no leaks.
Crank case vacuum is 0.6 to 0.8 bar, so 9 to 13 psi.
Also, don't forget that the kit has to be very thin, otherwise you affect bearing clearance.

Never had an issue with Anaerobic sealer. Used it on case halves for small engines, transfer cases, etc. Never used any thread.
