Sohc timing Chain

[Zeph240sx]

Hey so my sohc ka got a timing chain rattle during cold start, so i pulled the valve cover off
but i still see both guides are still there. But there is some slack on the plastic side (right)
Is this normal or do i have to tighten the chain somewhere so that it will not cause rattle on cold startups?

Timing chain tensioner?

[blkvrtswp]

FSM should have the procedure to reset the timing chain tensioner. It is oil pressure driven. Could also be a bad tensioner or bad oil pump. I did a SOHC timing chain job once @ 95k miles due to loud intermittent ticking lifter noise expecting to find broken chain guides and found barely any wear on the guides. Replaced them anyway but I believe all the noise was due to a tired oil pump - I replaced that too.
