Might be inheriting the umask of the parent process. Although you explicitly set it, I would take a poke at that.
How is syslog-ng being started? Can you unset it or set it to 0000 before starting syslog-ng as a test?

Already tried directory mode 04750 - no dice. It strips the g+s.

And dir-group ("group") when you aren't a member of that group probably won't fly.

I just need it to not touch stuff. It can only inherit these perms. It can't make them.
