1377c - Was Leaking Down, now it isn't(sort of), does this make sense?!?!?

My stock 1377c started leaking air on low pumps out the barrel with pistol cocked...so I took it apart, wiped some grime out of the valve and delrin/plastic seal. Noticed the cone shaped delrin seal was rough feeling, took some 1200 grit paper and light sanded it smooth, put it together...

Cocked gun and put a pump in, now its leaking louder and faster! Dumped the air and cocked it and started pumping again, at around #5 or #6 it stopped leaking out the barrel so I pumped it up to 10 and let it set for 10 minutes, dry fired it and it sounded louder than previous...

Cocked it and pumped it 15 times and let it set for another 10 minutes, dry fired and it was loud, now I cock it and give it 1 pump, no detectable leaking and holding that 1 pump of air for about 5 minutes but after 10minutes its leaked empty!

Any thoughts on what to do?

Regards,

Tony
