MH55S (wagon r) timing chain replacement

[Wagonrproblems]

So I have a stingray with currently 93,000kms and the car have been bulletproof reliable. So as preventative maintenance I'm wondering if I should change the timing chain if so at what intervals. Also I'm interested to know the routine maintenance that should be carried out at 100,000kms.

wagon r 55 has a timing chain i don't think this needs routine maintenance. because in the face book you get the wagon r club log in there there are use's who had done 200,000 and no maintenance issues.

Make sure you don't wash the engines as this will lead to the adjuster issue, this is great car for 2-3 people.
