I'm on my 3rd drain plug. I over torqued the first one and damaged it internally; I carefully torqued the next two to the proper spec. The 2nd one leaked, and the 3rd one (currently installed) leaks.

Oh wow I see a trend here. Maybe we should start a poll on how many have leaks.

When you over tightened the drain plug, you may have distorted the sump cover opening enough to cause the other leaks.

Is there an alternative to the aluminum crush washer that is safe to use on these cars?
Better off with copper maybe? Also, I noticed the head on the mcd doesn't have a nice flat surface to sandwich the crush washer like the LN magnetic plug and the own plug have. Can a washer be added to this and then the crush washer?

At one point, I reinstalled a standard drain plug out of frustration, and it did not leak.

Because its very soft and will conform to mis- machined surfaces better than anything else you can find.
