Safety wire can serve as a tamper proof visual too.
My knock offs are safety wired. Depending if you wire them before or after the knock off ear is up to the individual. Example; if the wire is slack then at a quick glance you can see the knock off has backed off.
My Aviad pan has a tab to safety/tamper wire the drain plug. My KN
oil filters have a provision to safety wire them too.
Internally many engine builders will wrap a wire mesh screen around the
oil pickup and secure it with SS safety wire. Keeps shear pin bits out of the pump. Ring gears too are sometimes safety wired. I had my ZF ring gear safety wired on my Pantera.
Also' the safety wire pliars are trick. Here in the US they can be bought all day long for under $25. Once you use them you would never go back to hand twisting.
As well as providing function and good looks they provides a nice comp look if you are in to attention to detail.
