What are the torque specs you guys are using? I think (just going on memory since I'm not home) that I used 50 Nm.
I'm not a bit worried that maybe my torque wrench is horrible out of calibration.
Both times were DEFINITELY with new crush washers.
I have never had a oil leak from the drain plug OEM or LN. I rarely use a torque wrench to tighten it but I have reused the crush washer & zero leaks. Maybe your sump plate has a small crack or imperfection in the sealing area.
