Ok, I am royally confused. But without draggin myself to a mechanic just yet, I was wondering if anybody might know what this is. When I start my car, there is a noise that sort sounds like 2 metal pieces scraping together. It goes away at around 2500-3000 RPM, but comes back when the tach drops again. Recently, when I first start up, it sqeelches really loud, and gets worse when I accelerate, but eventually goes away, but that weird scraping noise is still there. When I bought my car, the guy told me the water pump and timing belt were just replaced. Anyway, if anybody knows what this could be, and how serious it is, any help would be greatly appreciated.
