Noise Under the Hood - No Code or Chk Engine Light


Recommended Posts

My 2009 LS460 with 230,000 has developed a pretty loud noise from under the hood.  Sounds like a combination of rattling, grinding, clicking, whirring.  I can hear it when at idle if I open my door.  Transmission shifts smooth, but noise seems to accelerate with rpm increase meaning it's not louder but the whirring gets faster.  The engine temp is normal but a few months ago the temp spiked and display said overheat, but then returned to normal quickly.  Spiked again a few days later and then returned to normal.  I just had the front brakes replaced; mechanic installed new discs and stated my rotors are good.

I have only had the vehicle a year and a half and have driven it 8,000 miles.  It was a one owner, dealer serviced prior to me.

 

Any ideas? Thanks!
