Engine Noise


Vehicle Information: Model: Carrera 2; Year: 1991; Body Type: Convertible; Engine (type, size, modifications): 3600; Total Mileage: 85000;

I have noticed an noise starting to come from the engine area. I took it to the Porsche dealership to check it out. They informed me it was the air compressor. The noise does sound something like a squeaking belt. Rather than replace the compressor at the time, I had them remove the belt from it. The noise is still there. It is hard to pin point where it is coming from so I took a hollow pipe and put it to my ear and the other end to various points around the engine. The noise actually sounded the loudest coming from the oil filter area. The noise is not constant, but it is getting more frequent. I am not a mechanic but can do minor items of repair. If I could find a worthy mechanic in the Nashville, Tennessee area...I would use them. Any ideas on finding the noise source?
