Anybody have a part number or place to buy the Aluminium crush washers for the Engine Block Drain Screws (one for each bank)? I used a bit of RTV sealant and the original crush washers to make sure it doesn't leak but would like to do the job properly next time. Tightening torque for the Engine Block Drain screws would be useful too.
Thanks all
Aluminium is the English spelling ahah

The measurements I took of the Crush Washer:
10.0mm Internal diameter
13.6mm Outer diameter
0.8mm thick
