Bummer.  If there is any chance there is enough thread left to hold the sender, use pipe goop, but keep it on the sender threads and out of the engine.   If that doesn't work epoxy the sender or a proper size plug in and find a new engine before it starts to leak again.

Good luck!

Subject: Oil Pressure sensor

Just purchased my first Westy with some oil leaking out of the oil pressure sensor. (81 air-cooled)

Bought a new sensor thinking it was just the plastic part only to find it was leaking through the threads which are now toast. Any suggestions on how to fix this?

Thanks - John.
