Question about Tools & Hardware - Others
This nailgun has several parts to the headvalve that must fit together properly to seal. Go to WWW.toolpartsdirect.com for a diagram of this tool. The part called the diaphragm is source of problem. It has thin vinyl walls that will fold over when you assemble. The piston will not cause the gun to leak, just make sure that piston fits snug into the cylinder. Loose oring on piston will only cause low power or the poston may not retract all the way back up. Some piston/drivers had a plastic ring instead of an oring. The plastic ring had a secondary oring under, however not necessary. You can use rubber or plastic, just make sure that the piston is not too tight or too loose. The piston oring is the only oring in the gun that can be cut to fit. It is like a piston in a car engine. The piston rings have a gap.

The dent in the wood is not caused by the air. It's caused by the set that drives the brad. Are you oiling it consistenly? Are the brads the right manufacturer for your porter cable brad nailer? From the information you give it appears that the brads are not advancing correctly or that the air pressure is not sufficient to dislodge the brad from the brad strip on the first strike - it takes an additional strike to break it free. The standard for adding oil is to add ten drops of air tool oil for every hour of operation. That seems like a lot, but the correct amount of oil is a sure way to prevent most air tool problems.

Testimonial: "Thanks for the info. I was not oiling it at that rate. Is there anything I can do to fix the issue now that I didn't prevent it?"
there is an o ring in the trigger valve referred to as a Purple o ring that is probably split. If you can find a air tool center that has them you will save a lot of money versus replacing the trigger valve. Let me know what you are going to do and I will help you with the removal of the valve.
