Tappet

Moving part of an engine that rattles when loose resulting in engine failure. Slang usage as someone who's tappets are slightly loose (not quite with it - a.k.a someone who is a few sandwiches short of a picnic)

South African variation is of a tappet being a redneck in the american sense of the word

Donny is a real tappet.
Harvey is so tappet
