Okay that makes sense and I am positive that that noise is the chain because only a chain would make a noise like that. It only happens on the return from higher RPM and right above idle. I am going to try thicker oil and experiment with different oil filters because it may have to do with a crappy one way valve on the filter. If these don't work, I bet that faint sound will start to get a lot louder in about 50k miles and then its timing set time.
