Hey if your not happy with the compressor and seeing that you bought it on ebay, there are actions that you can take. I dont know what you paid but if you are unhappy, return it or contact the seller and let them know what is up. Most of the time they are very concerned about their seller rating and therefore will work with you to make sure that you give them a positive rating. I bought a back up compressor on ebay and it was soaked with oil and needed a complete cleaning to work properly and the seller refunded me half the cost to get it into working shape.
Let them know whats up. Dont settle for something that may not work properly.
Good luck.
