Here's my weird engine noise.. help me
Car information : 2011 / Lexus ISF / No accident / nearly on 60,000 miles / stock, no mods
Hi you all ~ what's up?
These days I suddenly found my F 's engine noise..
I'm glad someone give me an advice to this problem
At first, please watch this video
http://www.youtube.com/watch?v=VpWPe...ature=youtu.be
The noise sounds like reading hard disk when you turn on your computer.
I couldn't hear this weird sound when cold start.
Engine starts to sound like this after diving enough time.
I can hear the noise from the front section of the engine.
I think maybe the section is more front somewhere, more close to grill.
This noise can be heared easily at front upper grill or down grill with closed hood.
The noise itself is not loud, can barely hear it.
I tested that the noise is not relevant to engine rev.
The noise sounds steady when I put on the gas
I can not notice anything different in performance
Lexus has no idea about this sound, same as other maintenace shop
But I do realy want to know the cause of this sound
Anyone can help me ??

Yeah ~ It's like clicking sound.. like that you click mouse button many times with quick speed and irregularly
I think there's no other sound except right engine sound and the noise I talked about

It's not a guess. My car made the exact same noise. I replaced the tensioner and the belt. The noise stopped. I would start there for sure.

I just had my tensioner pulley and belt done too and that noise is gone here as well.
Now my car idles kind of like my old LS460. Smoother , quieter, and with mainly just the direct injection noise
