Oil Leak From Sensor on Block????
 

I have a 1996 Eclipse with a 420A,

I recently purchased this car and replaced the head gasket along with all the other top end gaskets, timing belt, and water pump. I got it for real cheap since the head gasket blew. Everything seems to run fine.
I noticed I was leaking Oil, when I checked it out its not coming from the head gasket as I feared, but it seems to be coming from a sensor on the engine block. When I crawled under the car there are two sensors on the block, the one that is leaking is closer to the transmission on the drivers side and a real pain to get at. Is this a known issue / problem with these cars.. what is that an oil pressure sensor?
I have to assume it was leaking before and I just didn't notice since I really just made sure it started prior to digging into the head gasket and didn't want to run it long with water in the oil.

Any ideas or comments?

Well, I do know my CPS is leaking oil. Honestly, don't worry about it. Its normal and doesn't hurt anything. As long as the sensor doesn't get oil on it and u get a check engine light, its not a big deal. If you want, the only way to fix that is to replace the sensor.

check the o-ring on the sensor maybe it doesnt have a good seal

Update, The Leak was actually coming through the Oil Sending Unit, $15 part and $10 special socket, replaced it and no more leak. I couldn't not worry about it since it was dripping on my exhaust and smoking like crazy and making a mess where ever I parked my car.
