Unusual Engine Noise I am wondering if anyone can help diagnose this. the past couple of days my 5.3L truck has made a very unusual sound at startup. The sound occurs on the passenger side of the engine. it sounds like exhaust would with headers, but it doesn't have headers. I've only used Mobil-1 10W30 in Texas since the truck was new (20,000 miles). any help?
