Craftsman Air Compressor won't build pressure and gets hot
I have the Craftsman air compressor 921.16680 and it will not build pressure past 20psi. It also gets hot around the copper tubing going to the tank. Air seems to be blowing out of the oil fill and sometimes the air intake filter. I've read the other questions and responses and tried to buy the parts suggested but the compression rings and scraper are not available anymore. That I find preposterous considering it is still sold new. How can you sell a product brand new to which parts are currently no in manufacture and are unavailable? I've seen the the reed valves and the associated plate can also be a possible cause of the problem. My question is: what is the likely cause considering the heat build up in the copper tubing? I've inspected the rings, scraper and the reed valves and to my untrained eye, they appear to be fine. My compressor is only 4 years old and I've put less than 10 hours of use on it. It still looks brand new, I really don't want to throw it away.
