2.5 TD smoking on acceleration (turbo issues?)

I pickup up my "new" 1984 D90 2.5TD recently and have been really happy with it - but suddenly I started to get SEVERE smoking when accelerating. Also noted some (not a lot) of the same colour smoke coming from one side of the turbo.

Here is a video:

I ~think~ it is an issue with oil getting into the downpipe after the turbo...

Back story:
I replaced all of the plastic and old leaking injector fuel return lines with Mercedes lines (and bled lines properly) which stopped all of the leaking fuel in the engine/etc. I took a good ride after changing the lines, experienced no issues (smoke wise) and let it sit for 2 weeks [work and kids], came back and one of the tires were flat...plugged it and started it up...and noticed the smoking issue. Turbo pressure is good at about 4 PSI, but not sure about the wastegate.

I also started rummaging around the engine compartment - as I am not an accomplished Rover guy yet - and noticed what seems to be a bolt missing from the turbo, some small leaking from below the turbo, and smoke "puffing" out behind the turbo when accelerating. (see attached pictures).

Does anyone have any thoughts on that (aside from putting in a 200/300 TDI), I would appreciate it.

Thanks,

Looks like White smoke to me.. And looks like you need a new turbo!

God I'm glad I put a 200 in mine!

looks a bit blueish and a new turbo at least i would look at 200 as probably cheaper than fixing yours as probably other issues as well as turbo

A 200 would be wonderful, but not realistic as the 90 has been perfect for me as-is.

I am going to pull the turbo and see about getting it rebuilt...while looking for replacement components as we do not have many 2.5 TDs around here.

Thanks again - and please let me know if anyone has any other ideas!

Cheers,
