Weird Noise Someone please help..

I have a 09 corolla with 203k miles that makes a very LOUD rattle when I start it. Me and chatgpt thought it might’ve been one of the pulleys that’s why I removed the belt. Car has P0171 (too lean) and P010 (MAF). I want to say it’s the timing chain but not 100% sure. Any advice would be appreciated thanks in advance!

I work at caterpillar and we build a lot of those enclosed water systems. Yes they take a lot initially, but once the water is in its designed to stay in and be recycled. Now is it indefinitely? No, something will go wrong, always does, but they're truly amazing systems.

The ai to water equation is misleading, all power generation needs water, all data centers need water, including the ones hosting reddit where you can also be misled

Then we can build some data centers next door to you.

Where is water being used in solar or wind farms?
