I've got 22 hours on the compressor side of my TB 302 Air Pak.

This morning I wasn't able to increase pressure at all. I was able to start the compressor just fine. The compressor motor kicks in when I turn the CFM knob on.

Oil is coming from the pressure relief valve. I did hold the valve open a bit while the compressor was running. I've done that in the past and only had air come out.

By the time I got back to my shop and fired it up, the pressure was able to be raised. A mechanic checked the compressor oil and said it appeared to be overfilled. I bought this unit new in 2012 and have never added any oil.

Any Ideas? Should I take it in? Possible blown seal?
