Once again eReplacement parts bailed me out. Their feature that helps you diagnose the problem along with the exploded view of the nail gun made it easy. I spent $10 in parts to fix a nail gun that would have cost me $110 to replace. If I could give more than five stars I would!
Quick shipping of the right parts made for an easy fix.

Porter Cable BN200A Air Nailer, would not fire - massive internal air leak

Tools Used

Removal of the cap (4 internal hex cap screws) revealed a broken O-ring. There was a gasket under the cap. I ordered the most likely parts to wear or leak. No other tools were required to disassemble enough to replace the piston seal, and another O-ring in the cap. I lubricated the O-rings and piston seal with Vaseline. After reassembly, the nailer performed like new.

1. Removed the cover from the nailer.
2 I replaced the head gasket and the seal.
3. I ordered the seal for the air intake and replaced it.
When all parts were replaced, I plugged the brad nailer into my air supply and was able to shoot a number of brads into a piece of oak with no problems. There were no special instructions necessary, I just used the diagram included with my Porter Cable Brad Nailer and replace the parts. Now it is working just like when I bought it.
