Alias...Dunno, kinda thought that too. I just read that spun bearings post, same sound except my oil pressure light has NEVER (Knock, knock) came on. The sound is definelty heard on the drivers side only, you can barely hear it on the pass side.
Oh, and when I start the car in the am (cold engine) there is loud intermittent chirrping/metallic noises coming from underneath the car...last's about 3-4 min until it warms up if let sitting at idle. Sounds like its coming from the front of the exhaust system, near the engine...like a loose heat shield or something, of course I can't find it. Been there for over a year. Probably should have mentioned that huh.
