WERE IS MY SECONDERY AIR INJECTION SYSTEM LOCATED ON MY 1995 CADILLAC DEVILLE 4.9


The 1995 Deville only came with a 4.6 Northstar engine and I don't think it has a secondary air injection pump - that was introduced in later models.
However, if it is in your vehicle, it should be located near the EVAP canister at the bottom inside the front left fender forward of the tire. It will be an electric pump and it will only operate for about 15 seconds or so when you first start the engine - you should hear a whining noise from the pump if it operating correctly.

Why is my car leaking oil its a 1995 cadillac deville sedan with 108k on it


because it is 15 years old. Engine seals dry out and deteriorate over time. Just a guess, but I'll bet the oil is coming from your main seal or valve cover.
