The engine was running ok, just like you see in the video. It did not lock, just that there was this extra noise. I will let you know what was the issue once I find out. I got the car 3 months ago, and to my knowledge, the oil has been changed in time, but it has 176k km so I think it might be because of usage. I think it was a bit abused. However, I paid 23k on it so I was expecting some issues, but … maybe not so serious. Any idea what else I can do since the engine is out? I was thinking to remove the cats, but I don’t know how to do this. Do they just get cut off? or do I also need some other updates to avoid errors?
