pretty odd I'd have to say. Check the mesh vent behind the tin- reach your hand over the top of the engine and you can feel it. sometimes that gets clogged. Also there could be a problem with the sending unit

I bought a dipstik-thermometer which was worth every penny of 40 bucks.
Then installed a aluminum oil cooler which changed everything. My 52 year old oil cooler had such dirty fins and was so fouled it was useless.

Yes, a sudden change like that is gauge or sender or bad ground.

The sender works (if memory serves me correctly) by adjusting the resistance to ground. So a sudden full-scale deflection would most likely indicate a faulty sender or that the wire to it has gone to ground someplace. Happened to me once in the 914-6. In that case the wire came off the sender and was bouncing around causing rapid full-scale deflections of the needle. Cured by reattaching the wire. Disconcerting when it first happens though.
