Default DV O-ring help!!!

I keep going through o rings on my dv holders..is there some ridiculous special way to put a damn o ring on? i put some diesel on it, then slid it over and torqued it down..85 ft lbs. i believe. ive gone through about 6 now on two different holders..any help much appreciated!! thanks!

well the green o rings are literally getting pushed up around the DV holder..but i did leave those copper rings in there..when i got my 024 dv's from peak, the instructions said if there are copper rings replace them..if there arent any dont put any in..so since the new dv's didnt come with new copper rings i just left the stock ones in..do they need to be pulled out regardless?

I used dish soap then tightend by hand to make sure your not crossthreading

well i know non of them are crossthreaded cause i did put them in by hand..its just almost like i have to much fuel pressure and its shoving the o ring out..it only does it when i get on it..its never done it just driving casual..
