I have a Porta Cable pancake type air compressor. Thursday morning it sounded different and I didn't have any air pressure. It had a small hole in the top and I could see metal. Broken rod. I took it to the factory service dealer in Greenville, SC. and they said they would call as soon as they could. Saturday I got a letter from them saying that a new one was being shipped to me free of charge. Thats good service. :eusa_danc
