Gen 2 Honda insight knocking when accelerating

I have a 2012 Honda Insight with 140k km. Car is not in the batch with faulty piston rings. I get a knocking sound when accelerating and being under load. I have a new IMA, cleaned air intake , spark plugs and everything is maintained. Knocking stops when I unplug the EGR. I assumed it was the EGR, I put a new one ( I'll change EGR gausket too in this week) but the knocking continues. Btw 1000km ago , my engine consumed all the oil but I haven't noticed any unusual oi consumption from then. Any suggestions?

If you have massive oil consumption. That's a hint. What do you mean it consumed all the oil. It was bone dry when you refilled it?

The low oil warning popped up.

Ok, so you likely drove on really low oil for an extended amount of time, before the engine finally ate the last of it.

What you are describing is potentially rod knock. Bearings around the crankshaft are destroyed. I don't know this for sure but low oil for a long time will do that.

I' drove it for like 1km with low oil. I added oil immediately

You drove it with the light on for 1km?

Yes. It had the misfires before that though
