I have an oil leak that just happens to drip on my exhaust pipe and smoke and smell terribly. It is driving me nuts! I have looked up to where the oil is coming from and it looks like the pressure sensor. There are two wires coming off this thing, and it plugs in just above the filter. I am going to swap it out myself, but I can't tell where the wires go! Help! Oh--it only leaks while running, when it is shut off there is no leakage. Here is the weird thing: After putting a new exhaust system in (it sounds and runs sweeeet and servicing the tranny it leaked worse and now it doesn't at all. I don't get it.
