funny noise from engine

Hai, i have bought a fj80 1992 with 1hz engine, since the day of purchase, i have spend thousands in replacing worn out parts and the list are as follow:

1) engine oil
2) power steering oil
3) engine belting
4) fan belts
5) re coil the starter motor
6) brake fluid
7) clutch fluid
8) front hub kit
9) 5 pieces of yokohama 285/75/16
10) front rod end

Did i miss anything? Anyway, i really like the way it perform, until recently when i drove it for long distance from my town to another town 60 km away, in th returning trip, i could hear these sqeaking
noise comig from the engine compartment, when i ease the clutch pedal the noise reduces, what could have caused these noises? thanks

Could be the trow-out bearing, but you'll probably get a better response in the diesel tech forum,

we don't get diesels or manual transmission here in the states

I'm just jealous that you even have a clutch pedal! Wish I did. I'd take a little rukus for a clutch pedal.
