I own a 2003 For Explorer 4WD with a 4.0L SOHC V6 engine with approximately 109k miles. Not too long ago, when the car was started, there was a loud bang, the vehicle shuddered, then the engine died. Since then, the engine will turn over but produces a loud noise that almost sounds like a rapid machine gun noise with a strong smell of gas Despite my best efforts, I can't pinpoint where the noise is coming from; it seems like it's coming from all over the engine. It is not an accessory since removing serpentine belt does not eliminate the noise. Do you have any thoughts on what it could be? My fear is that is timing chain cassette related, which is a hefty cost to fix.
