Compression Test Results

Hey all,
Sorry for dredging up a dead thread but i need some advice. My landlord sold our place so we had to move and the duster took the back burner. I took the intake/rockers off so that I could check the cam so see if the move damaged it but I think it looks ok. While I was there I did a leakdown test. I don't have a real gauge, just a way to pressurize the cylinder, but I figured that I would just listen for air and that would help me diagnose the problem. However, every cylinder that I tested had air leaking out of what sounds like the crank case. Even the bores that were the best in the compression test. Am I doing something wrong? Or should I assume that there are ring issues all around?
