Do you hear the turbo whine/high pitched noise when it's pulling?Do you know for a fact if the turbo is working?Is fuel pressure correct? Is the exhaust system sound very quiet?If it does then it may be restricted.

turbos make a whining noise at a load like taking off or pulling or full throttle and some turbos after they warm up and are staying at a speed not under a load the whining will still be there but you wont hear it over the road noise some are self oiled some you need to check from time to time

Start at the turbo and check for loose or blown air lines . Check the intercooler for cracks. The turbo whine is normal but you would not be hearing it as the turbo is controlled to vary the amount of boost needed for the throttle setting. If you have to use starting fluid to start a diesel then it is time to consider a re-ring and bearings for the engine.

It maybe the problem of V8 6.5 turbo diesel. To use the turbo success, the car must be reached the high certain speed. So it maybe the normal that whining sound coming from engine. Diagnostic engine regularly.

fuel injection pump is failin or has issues--getta haynes manual for pro car maintenance

SOUNDS LIKE A POWER STEERING PUMP NOISE, IF THAT IS NOT IT THEN IT IS THE FRONT PRESSURE PUMP IN THE TRANSMISSION.

check turbo tubes for oil. If wet turbo is leaking. otherwise you may have rings leaking, how is compression?
Also there is a crankcase pressure soleniod in left side of enigine block, it should NOT rattle.

i have a chevy 6.6 turbo diesel silverado a/c quit i need a diagram

It is inside the transmission. It is called a reaction sun shell, it strips out, which causes the grind noise your talking about.
