Noise started a couple days ago. I thought it was the AC compressor getting ready to crap out but I don't think it is. Wife took the car last night and when she pulled into the driveway i heard this awful sound. It comes and goes at idle and while driving. Doesn't speed up with acceleration. What do you think I'm dealing with here? I thought perhaps TGV but now I am thinking something with the driver side head. The car idles fine. No CEL's

That sounds pretty bad. I'd check the tensioner for the AC first. Remove the belt and run it without. If it's not that I'd check/replace the timing belt tensioner. Either way it sounds like a bearing is sh itting out.

I cut the AC belt because I originally thought the compressor was crapping out but the noise continued after. I pulled the front timing cover on the driverside and there appeared to be metal shavings on the upper intake cam gear/pulley. I went out and bought a hoist and engine stand so hopefully this weekend I'll have a better idea of what I'm facing.
