Oil leak are temperature sensor

I just got my defender back from the mechanic (replaced clutch and transmission) and I'm now noticing a bad oil leak.

It's leaking from the sensor right above the oil filter and oil cooler lines connect. I assume that's the temp sensor?

Is this a common issue? Is there an easy fix? I've tried tightening the nut at the base of the sensor.

That's your oil pressure sender.

When you went to tighten it, did it feel snug?

It did feel snug. I suspect the cover might already be cracked. The leek seems to be coming from the sensor itself (close to the lead at the end), not the base where it meets the nut.

Yeah it will be the same part across all of the 3.9 motors, so if they don't show it for a Defender try telling them a Discovery.

A quick check on NAPA's site show it for $14, Autozone is $16.
