I've been looking everywhere for posts or a part number but no one has been able to help. 03 LB7 leaking oil from a sensor on the drivers side front right behind the power steering pump. Some have told me that it's the oil pressure sensor, however the sensors I've been seeing aren't this long. Any insight?
I can't tell by your picture, but I suggest maybe going to a GM dealer and have the parts guy look up your vin and the diagram showing the detailed parts and location of the sensor on your engine.
You don't have to buy from them but they can tell you what sensor it might be.

since oil is leaking Id naturally come to the conclusion that the item had to do with the engine oil. Can't be fuel or coolant related or those fluids would be leaking.
What else is there on the oil system that would be exposed and possibly leaking?
Just seems common sense to me. Why not go to a parts store, ask for an oil pressure sensor and see if it looks like what is leaking on your engine.
