I just bought a 96 eclipse. It is leaking oil. The problem is we have no idea what sensor it is leaking from. We thought it was the oil sending unit and bought one and it isn't it (though it is right next to this) but it is larger. I have a 2.0 and the part is on the drivers side rear of motor (bottom) and right below oil preasure sending unit. If anyone has any ideas of what this is please help or if you have a book you can look in you have no idea how much I will appreciate it. I love this car but i hate the leaking oil!
