Temp Gauge Issue

My temperature gauge is not working normally. Prior to my head gasket and thermostat replacement I never got any temp readings on the gauge. I found the previous owner had effectively no thermostat in place during the repair...

I cleaned the passages in the head, block, added a MM thermostat, and replaced the head gaskets. I used a teflon based pipe sealant (Loctite 567) on the the threads for the sender and adapter in the head. My gauge is funcional now, but I get fairly rapid temperature swings on the gauge. Faster than what would likely be happening in the engine. For example, a swing from 160F - 200F in a few seconds...

Is it likely that the sealant is the problem or something else?

Thanks
