Timing chain tensioner... no more issues... like forever.

The s2000 has a known issue with the timming chain tensioner. It has little spring strength and after some heat cycles it starts to loose strength progressively, until you hear a rattle while idling. 

This means that, unless you're pulling it and passing oil pressure throught it, it's not producing enought force to counter the slack that the chain gains over time.

This becomes more evident if you drive with thinner oils or on warmer climates.

The solution ia to replace the load spring with something... well stiffer. However, assempling it back is a pain in the ass as the parts need some sort of force to counter the auto adjustment screw, but, the original part, has this as a sinple retainer and that is just a no-go.

Solutions? you can evidently replace with oem, and spend your life doing it every 30 to 50000km. You can transform the part yourself, or you can just buy a track ready part from TODA Racing engineering. Guess what I chose? oem parts out, racing parts in ...the usual!

Install is easy and you can do that in 10 mnts.

The rattle is gone, but that again, a factory part would be the same for a while...it's the future that will tell.

lovely!
