96 GL 2.0L When changing the oil this weekend I noticed that the oil pressure sensor is leaking So I went to oriellys and bought another one and went put it on but the problem is I cant get the old one out.It dosent really look like it has a hex shape for a wrench or socket. I put a socket on it but it started to slip so I quit before I broke something.Is there a special tool to take these off with.
