    strange noise from under hood.

    i have a 00'fomula ls1 with 95,000 and tonite on the way home i got on it a few times on the highway.i heard a sound like it was a lifter rattling, then i thought it may be something in my fan.i pulled over and it sounded horrible, but all the guages were fine. i get back on the highway and it ran fine, until i get to a stop and it started again. i get it home and pop the hood, i thought it had spun a bearing or maybe some kind of top end issue. i turn the car off and crank it a few times and no more noise. not familiar with the ls1 motor, so any help would be great.thanks

    Check all of the pulleys, water pump, PS, Alternator, A?C compressor and Crankshaft pulley for looseness, signs of wear, metal dust etc. Often when you hear a sound at idle or low RPM that is intermittent it is from pulleys or accessories.

    What if you popped the hood and a gorilla jumped out.

    Water pump took out the A/C, maybe. I've been told that can happen. Disclaimer: I am not a car person. I probably don't need to tell you to have the car checked.
