Loud squeaky noise from Turbo charger when engine cold 2001 ZD30 3Ltr 240000ks

Sorry guys forgot to say Hi, so frustrated with this noise, been working on it all weekend and still can't find it.
Noise I have only happens when the actuator opens. Have changed the dump pipe gasket

Not too late and plenty more info in the forum than from the manuals
Highly recommend you stick around, great bunch of blokes IMO

Sounds like exhaust leak near or at exhaust manifold. Possibly blown/cracked gasket or cracked manifold, stuffed turbo base gasket etc. You can't see it because of heat shield. As the engine/exhaust heats up the gap/crack closes up again. Don't discount EGR pipe either.

Note: why is this thread in gearbox section?
