Great video, thanks for this. As others have said, looks like classic flood damage. The fact there are others with the same issue is indicative of more of these cars getting driven through floods.
So glad to have seen this vid/info as a new Aygo owner all relevant info is much appreciated! Note to self - be very careful in flooded areas AND do not jet wash the engine bay either.
Greatest video quality i have seen for this engine and tremendous patience. Many thanks for doing this Dave. Please do continue doing more videos on this engine e.g. repairs, fault finding, maintenance. Keep it up!
Exactly the same here. 2009 Toyota AYGO with 75k on the clock bought from auction with an engine rattle. Run just fine but a terrible metallic knocking. After watching this video, a quick compression check highlighted an issue on No. 1 cylinder. Whipped the sump off and hey presto there was the telltale chip from the bottom of No. 1 cylinder and what looked like a bent conrod. Lots of wrestling later and with the engine still in place, piston and conrod have been removed and it looks exactly the same as this video. Not sure I’d have believed it without watching this. Many thanks for taking the time to document your progress for others to benefit.
I suspected a sticking valve or a worn camshaft lobe. I never would have guessed a bent con rod. You have a lot more patience and positive attitude then most (including me) Thank you for taking the times to make this video.
Looks like evidence of Hydro lock water ingestion my daughters second C1 suffered the very same issue, even though the air intake is up high she'd managed to get water into the engine through flood water and limped home, stripped the engine and found the very same bent con rod on No1 and damage to cylinder bottom wall. Managed to get the block machined and to this day has 108.000 miles on the clock and runs with no audibly sounds on knocking.
First class diagnosis, look at the oil feed to this tensioner-1/8-3mm hole easily blocks up and your tensioner was not working, most likely cause of the bent con rod the the defective tensioner. But excellent work!! well done!
Wow that was really interesting. who would have thought con rod................. I was rooting for ya' at the end as to what it was causing the knocking noise
Great footage,. For strange engine noises, i use a stethoscope to try and narrow the area down, Anyway i trust you refit the new timing chain kit over to the replacement engine
got the ssame issue..just a bit softer tikking..tnx for graet vid !! it sounds like a diesel !! thank GOD its not the timing !! got me a bit worried there !! i saw a video where they was testing a brand new c1 in a car testing show and it made the exact same noice..they said it was because its a 3 cylinder :O

Fantastic video! 10out of 10! I hope to rebuild the engine in the future!

Just bought a 2016 C1 with a slight noise similar to this! Great Video, thanks Dave. I can now investigate the noise.
Perfect video and explantation. Thank you. I have same engine ( peugeot 107 ) and almost the same noise.

Possibly water sucked in. It doesn't compress so will bend the con rod. My Peugeot 107 (same engine) is on 199,250 miles still running great!
Excellent video
