So I was in a hurry, looking at Ft-lb instead of n-m, and was probably at 50nm (instead of 40nm) on drain plug when I realized my mistake. Filter nuts probably reached 30nm (instead of 20nm) None of them got stripped, and I loosened/re-tightened the oil filter nuts to proper torque. I didnt touch the drain plug, but am considering replacing the copper washer with the 'non-copper' one from the filter box and torquing it properly..? I'm worried if it will fail somehow when heated up. Advice?? Insults??
