Only things can cause feedneck or breech leak. Breech oring, stem oring or sail oring on your techt and something is causing them not to work properly. Reason why they leak:
1. Breech is dirty where the oring sits- clean it with alcohol or brush it in the sink with tooth brush with soap. Common sense you shall disassemble the whole gun for this
2. Orings are worn or damage- change it
3. There are debri on the bolt or where the bolt cycle through-clean it there may be gunk in there and adding more lube creates more gunk.
4. Wrong size orings-change it
If the soleniod leaks it would in the frame or the bolt will get stuck forward position. Easiest and cheapest fix is clean your gun internally.
