ok lets start with this, the noise you hear is most likely a timing problem. It sounds like your exhaust valves may be coming into contact with the piston. Pretty serious problem. Next as far as the truck ..you need new strut rods..and probally have a bad bulb in the dash. best bet is to take out the plugs and scope the motor. look for any scarring on the top of the piston. let me know what you find and ill see what help i can offer.
