here's a timing chain replacement video on a Hyundai i1 1.0 3cyl engine. The car had dealer oil changes, so that means they used the bulk Acea C3 oil most likely. The interval for us was 15.000 km or 1 year, I would expect in the UK 10k miles/1 year. It's a port injected engine.
I started the video with a good look at the aluminium valve cover. I've mentioned several times before these things wreck oil, I've seen some with stuck forever dipsticks.... so for the non believers, take a look. No engine that had a few oil changes should look like that in 70k miles. No wonder the chain made chuffing noises.
And these were some of the better ones, the 1.6 and 1.4 are worse. Note also that the camshaft area looks deceptively better.
