I'm in the process of replacing the cork sealing disc on the oil filler cap (Number 8 in the diagram). Problem is the cotter pin (12) used to secure the nut (11) is only 1/32" in diameter and I can't source any. Flying Spares list the part ( X4648Z) as no longer available.

So shall I use fuse wire to secure the nut. How about threadlocker. I really don't want this nut to work loose over time and fall into the engine, along with the spigot washer. What's the collective wisdom on this?

Thanks for the replies.

JeffR - You've supplied 2 great links there - I'll save them for future use. FMW fasteners have them at 10c each with $10 P&P. That's a great deal for these hard to find parts.
