Kind of beginning to think so. It only happens at 1900rpm though then goes away.

Yeah, sounds like a guide has gone MIA and the chain is rubbing aluminum. Alternate theory, a bolt has backed out of the DS main guide and is rubbing the chain case.
You need to inspect this ASAP. Remove the upper timing cover at minimum. I suspect that you'll see pointy teeth on your cam gears as well.

I will do a tear down over the weekend. In the mean time i went ahead and ordered a timing kit and some other misc stuff from fcp euro. I'm really hoping my cam gears arent shot that will be the death of me financially after ordering all this shit.

You will no doubt get a pm from me.

I look forward to your tear down/inspection results.
Not really, it's the most fragile part of the system, but it should be under $120. Best real solution is to go early E36 M42 timing case, which is a fair amount of difficulty and cost.

I look forward to your tear down/inspection results.
