Brakemaster Air Dryer Model 68

[jmacstack]

Hello Forum, There is an air leak in the base plate around the screws of my Brakemaster Model 68 airdryer. There is some dirty oily residue also around the baseplate on the bottom of the unit. I have been doing some research and have found out that they no longer make the model 68. In fact Brake Master sold the company sometime ago. I looked into getting a rebuild kit....which I believe includes a filter and a new spitter valve. They don't make it anymore. It looks like I may be having to replace the entire unit with a new one. However, if it is in fact oil that is finding it's way through the air leak then perhaps the rings in my compressor are shot and that is a whole different situation. It would not be smart to install a new air dryer with a bad compressor. Can a compressor be repaired or will I be potentially replacing the entire compressor? I would so appreciate all thoughts, opinions and or questions. Jennifer
