Ford ContourFord Contour combines sporty driving dynamics with the comfort and practicality of a four-door sedan. It doesn't have the rear-seat space of a Taurus, but Ford improved rear legroom and revised the styling. Contour SVT pours on the coal with a higher output version of the Duratec V6, a sports suspension and bigger brakes.
I have a strange issue with my 96 Contour (2.0 DOHC 4 Cyl.). It sounds like an air leak in the lower part of the engine just behind/above the A/C compressor. This includes a very minor oil leak associated with it. You can hear what sounds like the cylinders forcing air out that alomost has the same sound as a warning spring on break pads except that it changes pitch and frequency with the RPMs.
I have tried to see behind the A/C compressor but the area is pretty well hidden. Can anyone give me an idea what might be there? I have searched manuals and can't see anything. I don't want to spend hours tearing the engine apart to find nothing.
Thanks for the thought, but this car has a Cat-converter. The EGR system is tight (and the noise is coming from the other side of the engine. I'm pretty sure its not a vacuum leak because 1. I can't see any vacuum hose going to the area and 2. I'm getting no trouble codes. For that matter using a realtime scanner the engine seems to be responding perfectly. The whole issue isn't causing any issues currently, just making noise.
