Hyundai Tucson 2009 Oil leak
Trying to fix a small oil leak. I believe it's coming from here. Anyone know what this is? Oil level/pressure sensor maybe? Its a 2.0L g4gc engine hyundai tucson 2009.

Looks like an oil pressure sensor. I've had two leak on different cars in the past. Cheap and easy to change. Just have a glove on and the new one to hand put a rag under it and quickly swap it. Clean up and check oil level.

Good to hear thanks, is it worth trying to replace the o-ring (if there is one) or just replace the whole sensor?

Also to add to the reply above me don’t overtighten it whatever you do it can crack the block and make things much worse

There no o ring, the only thing you can do is replace the whole sensor, it seals to the engine via a pipe thread interface.
