Hi again, I got my new green o rings today for my p17, it was easy to take it apart and put it together but after I was done I noticed leakage. Bad enough that I could clearly hear it. Now, I wasn't able to take the valve apart and though I used a padded vise I managed to scratch the stem >:(. I figure that's what's causing the air leakage. Any thoughts?
Since I wasn't able to take the valve apart I was forced to inch the o ring over the spring, I figure that's another reason why the gun leaks, maybe I scratched it in the process.
Any guidance will be appreciated.
Thanks
Martin

So after getting some guidance from an expert I was able to take the valve apart, polish it and replace all the o rings. I smashed the spring when I was trying to take it apart so I fixed that also. The gun shoots like a champ again without any air leakage.
;D

No sense in starting a new thread... so here goes.
I did the o-ring replacement, valve seat polishing thing, this morning. What a difference!
I was losing pressure if I let the gun sit for any amount of time. Within two minutes, there was not enough pressure to clear the barrel; it had gotten to that point as this week progressed.
I studied here, and, Youtube vids, on how to work the trigger mechanism, springs, and, of the internal pump works; valves, o-rings, etc.
I found what was some deformation on the valve seat, for lack of better description, it looked like a spot of resin, or something akin to that. I buffed it out with a green scouring pad, faux steel wool pad, cut into a small spinnable polisher pad.
Then, a trip to Napa Auto, and their wonderful well stocked box of rings, and, back home we run. There was only one spring that I had question about, and it was quickly solved in a review of the vids.
Results: well sealed, and a sharp cracking report. It has held seal in a half hour test now. Heck, its only been repaired for an hour, and I had to shoot it to make sure it works.
So far, so good.

I enjoyed upgrading the o rings that I got a second gun to do it all again lol. It is a great gun.
