I don't think people are having problems after they've serviced it once already. It's from the factory that it was installed so tight and the many heat cycles as the vehicles get older. I purposely undertorque the fill plugs as it's not an area that requires high torque. I just don't need it to leak. Good on you for checking your values. I've mixed up my values before looking from one source to another. DD as they say, due diligence.
