02 1.2 Timing chain - wrangler_rover
My son has a Corsa C, 1.2, 16 valve, 52k miles with full service history.
He recently had to take it to a main dealer for some minor work and was advised thet the timing chain needs changing as it is noisy, he said thanks but I will consult dad first.
How likely are these chains likely to fail?
Could they stretch or wear?
I imagine the results of one failing are catastrophic leading to major work & expense.
I thought the advantages of timing chains over belts was no maintenance.

Fairly quickly once they become noisy. A few thousand miles - maybe.
Could they stretch or wear?


Most definitely - and they do.

You've got that spot-on.

Manufacturer sales hype. Both belts and chains have a finite life; but belts tend to be easier to change.

what don't help is that they only fit a single chain not a duplex one but agree the chains are very long if left they either work there way through the case or they snap the cam exhaust one
