One turbo was original, worked fine but audible, mine was a
cartridge, brand new, and the other was either a cartridge or total
replacement (not my car). All three whined enough to notice. Good
air filters and associated plumbing on all three. I figured it was
normal.
Mine was bad when I got the car, probably form not using synthetic
oil -- I don't know what was used before I got it, but I would guess
not synthetic or diesel rated. At any rate, it finally stopped
turning at all when cold, making it somewhat worse than sluggish.
It also clattered when I got it, and I'm sure the cam is bad by now,
but I don't see how one could install the pushrod "backwards" when it
appears completely identical on both ends to me. Worn hole in the
head is a possibility, too.
No other signs of wear, but it quit starting a couple years ago,
probably a failed shut-off valve as no fuel comes out the injectors.
Or another pump rebuild....
