Sorry for the repost, but j-body was really screwing me up, changing my url link because it had the word $hit in it... Here's the video fixed and the post.

My cavalier is down, she runs, but she doesn't run strong like she used to...
These are the noises she's making, they're louder than the video would have you believe,
the best example is right as I crank the motor up, that's the extreme of the noises.
The noise isn't bad at idle, and on the road she's pretty quiet when she isn't under power,
but as soon as you get her up to 2.5-3 grand and have any kind of pressure on the accel,
she starts clanging, loud enough that I can hear it from the cabin at high way speeds...
Then if you let off the accel, she quiets up, but as soon as you touch it again it starts.

Does this sound like a timing issue? I thought it was a piston smacking valves (which I have
to assume are already bent if so) but a local mechanic that I know has worked on ecotec
2.2's initially said he thought it was the timing. We changed out the oil with fully synthetic
minus a bottle of lucas oil treatment, and no change in the noise. Now his answer when I
asked him if I should get the cloyes timing kit and change it was "We can do it and it might
stop or it might not change a thing"... Unbelievable... Anyone have an idea here? If it sounds
like I'm going to have to redo the rotating assembly, I might as well part it out, dont have 2700...

That sounds like a spun rod bearing.

If I remove the head and get into the block, can I just replace the bearing for the one rod making noise? Or is it going
to be a fully rotating assembly overhaul. Assuming this is a correct diagnosis.

You would go up into the engine by removing the oil pan to get to the rod bearing.

If it's spun there is a good chance you damaged the journal in the crank. It may be cheaper to replace the engine with a newer junkyard one and then open it up to see what went wrong.

That is IF the spun rod bearing suggestion is the right one.... but it does sound accurate. If it sounds like somebody is smacking the engine with a wrench as the RPM's come up and it gets louder, it's the bottom end.
