I purchased the overhaul kit which arrived next day. I disassembled the nailer and all the o-rings looked in very good condition and were well oiled. I replaced the o-rings anyway. The plastic exhaust valve appeared in good condition and was not part of overhaul kit so re-assembled and nailer still not holding air pressure. I did not go deeper into the forward end and instead took it to warranty service.
I measured all of the o-rings and sorted before beginning. One was a little too large for its numbered position so did not use ( Porter Cable error) The instructions in the overhaul kit showed one of the o-rings as the incorrect diameter where the owners manual was correct. Porter Cable goof.
Thanks eReplacement. Your video was a big help. My model is slightly different. Probably newer.
