It's the 3.5 liter V6 non turbo

Hello I am new to the forum and I just have a quick question no more than a week ago I noticed that my Oil Pressure warning light will come on intermittently while driving but specially while the car is on iddle. I noticed that this happen after an oil change was done. Now the weird part is that the light does not come on no more but I noticed that the car is leaking oil so I did the must common thing and check both the oil filter and the lug bolt nut of the oil pan to see it it was leaking from that area but to my surprise no leaks were found there but I noticed that from the area where I presume the AC compressor is located had a little of oil on it so I remove the plastic engine cover and found that where what I assume two sensors go into the engine block were cover in oil so I assume that this is were the oil leak comes from. ( Provided a pic of my findings). Now the thing that puzzels me the most it's that on the same side of the engine but on the back part its seems to look like some oil has leaked and stained the engine block. I apologize for the long post but I was hoping that someone can enlight me on this before I take in to a car shop for repair just to have an Idea what's going on or if I can attempt to tackle this on my own, what exactly are those sensor looking like parts that going the engine block. Thank you and best regards,
