Turbo Whistle noise

Post by cecilgreeff »

Hi,
My turbo is whistling when I rev above 2000rpm, not loud, but you can hear it in the cab with windows closed, no power loss, no leaks on turbo, and when cold start, I hear almost the same sound, like pulley bearing dry or something.
Took it to Toyota, mech said there was a batch of hiluxes where the turbos needed to be replaced, but recons this one is fine as it's not that loud to him.
I also hear a sound when changing gears & clutch deressed, almost sounds like turbo blow off valve, but my previous d4d did not have this.
Warranty ends in 2 months.
Am I paranoid or should I be worried?

I have same noise on my work d4d......means turbo is still working. :D:

Seriously, you do not need to worry about the turbo whistle! Some do and some don't.
The other noise....not sure what you mean! could be a dry clutch fork could be thrust bearing. Dont have enough to go on.

My 2006 has a very faint whistle (after 292 000ks - has always sounded like this) but my friend's 2014 3.0 D4D auto has a much more audible whistle. It has been like that since new and after about 30 000 ks it still sounds the same. Has not gotten louder and goes well.

Update: Went to Toyota for diagnostics, they replaced the noisy turbo, and diagnosed the other sound as gearbox bearings, replaced them as well, but upon opening the gearbox, found that all gears, 1 to 5 & shaft needs to be replaced.
