I have new aluminum crush washers coming in. It is the same size and same part number as the oil drain plug washer but I still have not decided what adhesive to use that will function as a thread locker and a sealant at the same time.

I have used Loctite 574 in sealing machined surfaces in aluminum transmission housings with great success but I have not tried it for sealing threaded connections. It might work and it might be worth a try to seal the threaded case, the boss, fitting and the washer flat sections. I'll give it a shot.

Thank you for the replies and I will post results.
