I have a brass temperature sensor about 14mm in diameter, no 'O' ring or
shoulder, just seals on the threads into an aluminium cylinder head.
What should I use to seal it? Nothing, ptfe tape, ordinary blue loctite,
plumbing thread sealing compound (a bit too permanent I would think) or
something else? Glad of any advice.

No taper at the end? PTFE tape won't do any harm.

I use ScotchClad thread sealer for everything that screws into my ally
engine. It seals, prevents corrosion, and locks.
