CM2350 High Pressure Relief Valve

[Hermjeji]

Was just looking over one of our trucks yesterday, 3 months ago it passed the injector leakdown test with flying colours, but noticed the below at the high pressure relief valve. I've look at quickserve at all of the testing required to see if it's bad or good, none of it really stated you'd observe anything on the outside of the valve. Spec for the torque asks for a 90 degree turn afterwards, so I would assume I can't just re-torque it, and then ofcourse that little sealing washer inside wouldn't be happy I assume.

Any advice on this? I'l re-run the leakdown test this weekend. If that passes, do I just leave this alone?
