Likely a tube seal.
This is an RX thread but the concept is the same- https://www.clublexus.com/forums/rx-...eplace-em.html

This is an LS thread, not an RX thread.

^ per bradland, "the concept is the same". You need the set of little ring seals, see e.g.,
https://www.clublexus.com/forums/ls-...-tube-seal.htm

Not what is shown in post 3
There are excellent videos of replacing them (under the valve cover secured by little bendable tabs).
see this around minutes 14-16.
