My recollection is that it doesn't sound as bad as the last one.

I did go back to that thread so I could compare but couldn't, because the video has been "removed by the uploader" (not sure why you'd bother removing it?)

Thanks for sticking with me on these posts guys. This is what I needed to hear. A thorough check and a test drive and hopefully this should be sorted.

Cheers

I recorded a video of my own for you to compare against. This is a cold start after sitting for a few days unused.

Skyactiv_G_Cold_Start_and_Idle.mp4

On starting, the ignition timing is retarded to warm up the catalyst quickly. It settles down after about 10-15 seconds into a more normal idle. The second part of the video is at idle after a few minutes once the blue temperature indicator has gone out.

Few things of note, the ticking sound is the high pressure fuel injectors doing their thing. They run at very high pressure in this engine (in the order of 3000 psi) compared to other petrol engines.

Also, this engine can switch between otto/atkinson cycle combustion on a whim using electronic phase control on the intake cam. Under atkinson running, some of the intake air is pushed back out of the cylinder into the intake manifold which can sound a bit boomy, for lack of a technical term.

As I said previously, nothing in the video you posted above, OP , sounds out of the ordinary to me, based on my own personal experience after nearly 7 years of ownership. With that said, treat all used cars with suspicion until you can assess it yourself.

Happy hunting and you need anything further, don’t hesitate to ask below,
