Outer Limits 4x4 Board

Hey guys so I got the car in pretty good condition after a front end rebuild and got the part time kit installed, all has been well but I have noticed after say 20-25 mins driving it makes a loud whining sound from the engine bay, and I mean loud, now I now it can't be a failed bearing in the motor itself otherwise temps would skyrocket but I can't seem to nail it down to anything in particular.

Anyone heard of this before and know what causes it/things to look for?

Btw 1FZ-FE 92 model

Thanks in advance

Edit: Another thing I noticed is the fact it sounds like a cricket in the gearbox or something, this is another sound that I am hearing when doing sort of over 80kmhr. Now you got two problems to help me with
Edit: All fixed, was power steering

COuld be the power steer pump making all the noise.....

I know they make a hell of a racket when they stuff up, and it is common for 80's pumps to kak em selves

Does the noise vary when u turn the steering wheel even stationary

Idler brgs on your cam or fan belts??

Viscous coupling in the fan. Will cut in and out as you drive along etc when ever the temp moves up a little

You haven't left your wife under the bonnet have you ?

May explain the whining

My mate had the same thing in his 80 petrol. Power steering pump. Try some heavy oil in it and if the noise improves, it would indicate that is the source.

Take it to a mechanic for a listern and he will tell you what it is....it could be anything from water pump to air con belt idler to steer pump to viscous fan...all have a different sound...
