You should be able to find a local Dewalt/Black and Decker service/repair shop and they will be able to sell you all the parts you need, I would recommend getting a full upper rebuild kit and replacing everything, while you have it open already
When you pull the trigger air comes out near the trigger and no nail is fired.
The problem that you describe indicates that the orings within the trigger failed. You could replace the orings if you have a source for very small rings (2mm x 1.5 for the firing pin inside the trigger valve) or just replace the whole trigger assembly (under $10). Lube all orings with white grease or silicone paste lube (remove head and lube head valve assembly). Good luck
My brand new DC608 18 gauge nailer jams every time on the 2nd nail.
Per your addendum I would have first told you to check that you are using the proper guage nails. Second you should make sure you are loading the nails in the lowest channel in the magazine so they are at the bottom of the magazine. If you load them into the top of the magazine they have more time to go off course before they get into the wood.
The gun constantly exhausts air when connected to
Easy fix if air is leaking out the top of gun. Remove the head and lube with white grease or silicone paste. If orings seem to be loose, order repair kit from dewalt (you can tighten orings by removing the oring and wind a bit of teflon tape in the oring groove). If air is leaking from the trigger, replace the valve. If air is leaking out the bottom where the nail ejects, pull out the cylinger and lube the orings that seal the cylinder to the body of the gun.
I have difficulty with regular jams regardless of
Depending on type of work/wood the finer the nail, results in increased jams. Eighteen gauge and finer experience more jams than say 15 gauge. Fine gauge nails also suffer from square cut tip. I believe that if the nails were pointed (like Senco nails ) they would more likely drive true. Jaming can be decreased by selecting the correct nailer for particular work. Dimentional lumber and hardwoods tend to increase problems compared to quality plywood or non wood trim materials. If you experience jaming with any type of wood then time to look at driver for possible problem. Check driver for bent or worn tip. Driver blade can be dressed square on grinder. Some drivers have a slight angle/taper ground into tip on the side that faces the rails. This taper continues up the blade about 1/2 inch. The taper will prevent the driver from hitting the second nail. On really hard woods, try drilling a fine pilot hole to produce best results. Good luck

Make sure the area where the nails slide through is nice and clean. Lubricate with some spray silicone. They may not be seating all the way against the nail driver mech.
