200,000km?!? You've got to be kidding me. There are car engines that can go longer than that before timing belt/chain service.
Uh what? An interference engine that is specifically designed to take into account timing failure? Like they "expect" the timing chain to fail????? If they (engine designers) expect it to fail, they set a required timing replacement at X miles before the thing has failed during testing. Thats the way EVERY OTHER on-road interference engine is designed, as far as I know...correct me if im wrong.
Thats like saying a car MFG "should put double tie rods and steering components on a car, in case one fails".
But what do I know, this doesnt have to do with electronics, so im a fking idiot and talking out of my ass.
