Hi all,
Got a D22 cheap (£150), but it's timing chain had jumped. So it wouldn't start, and after more investigation I can see the timing marks seem to be way out. When rotating, you can see the chain become incredibly loose, and then tight again. It almost looks like it's had the timing chain replaced, maybe it was a cheap kit or something. But my questions for those YD25 masters/mehcanics:
1. How could it slip so bad?
2. Why would the chain be tight partially when rotating, and then loose. (See atttached video)
3. Is this likely to be an oil pump failure related issue, i.e. oil pump went, and so did the chain tensioner due to that.
I plan to take the head off and chain the bent valves, slap it together and use it for a run around. I guess I'll see how bad the damage is once the head is off. It'll probably cost around £400 in parts to repair it, so I hope it's worth it.
Thanks
