Pest Coolant Leak! Temp sensor

Hey Y'all. my 22re motor is leaking coolant out of one or both of the temp sensors on the front of the Intake manifold. the ones that are side by side that the harness plugs into. it's not spraying out, but every morning i'll check it and there is some residule leakage alomost jelled radiator fluid there. looks like they have copper crush washer gaskets behind them, any suggestions.
doubt there a cheap part from the Stealership.

Replace the copper washers, shouldn't cost more than a buck or so, or maybe try Teflon tape on the threads.

make sure it is not dripping from the High speed idle unit above it. Fluid runs through there to and may be dripping onto the sensors.
