Hi there,
Yes the copper washer is very important and a bit of extra goo on the threads does no harm, especially after changing the oil many times the aluminium sump thread starts to become worn and maybe prone to weeping.
I am also very conscious of the fact that an ALUMINIUM sump housing and a steel sump plug can easily be overtightened and result in a cracked sump or sheared of bolt. So go gently....
Then the real trouble begins!
BTW if changing the oil in the diffs, the plugs to my amazement are made of black PLASTIC and can be over tightened and stripped very easily.
The transfer box plug and drain are the same as the sump and caution is needed as applied to the sump area. Go gently :whistling:
