Re: WOW ! I thought I was on my own...
You have the bonus of it being Japanese metal. Provided you do nothing silly like clog dance clutchless on max revs up and down the box or stick a valve through the piston, it will sit there tick tocking away for years.
One interesting thing, there's a little spring that goes with the pin and bush to locate the cam and gear. I don't know long term, but short term, it plays a real mean samba rhythm as the pin and the bush jiggle about. But it's not immediately harmless, just rattly.
