You don't need the 1K resistor.

This circuit can also stop the oscillations because it will present a load on the circuit.
To see oscillations in a circuit, you really need something with a very high input impedance. The circuit should be sensitive enough to see the oscillations without a direct connection to the circuit being investigated.
