Can anyone link me or give me the part number for the twist/butterfly (whatever you call it) filler cap for the gear oil on my 182 or ideally link me direct to the washer itself? A while back when taking it and changing the gear oil the washer dropped and got lost. I want to replace it but I'm not exactly sure what should be on there. I assumed it would be a copper crush washer, but the only picture I can find of one suggests it may be a rubber washer.
I've searched on eBay and the like but because I don't know it's exact name or what is meant to be on it I'm not having much luck.
