K24 from a high-milage car

I hope it's a 1.6TD version of the K24

Yes it is! It's from an imported Golf supposedly. Are there however any part numbers I should avoid, and if so, why? The flange matches...

This is how I usually do.
Have someone start the car while you hold the impeller still with a pen. Wait 10 - 15 seconds and the oil should have built up pressure.

whats happens to all the exhaust gases that want to turn the exhaust side?

Personally, I'd rather get the damage from 10s of unoiled unloaded turbo spinning, than the risk of holding a pen in the intake of a running motor.

I think I'll just oil it manually and then install it...

I'm not talking about sticking a pen into a spinning impeller here, or maybe I'm not so good at explaining...   

It must be kept still before starting the engine, and the exhaust gases are not That strong on idle.
And, exhaust gases pass through the turbo without any problems at idle..

At idle it wont spin until lubed anyway. Just don't rev engine until vane has been rotating of its own accord.

Lots of good answers

I'm getting the turbo next week and I'll probably start installing too, so stay tuned!

just prime the oil system after you install the turbo. thats definitely the easiest thing to do.

Good stuff!
Here's a funny story:
For the 10 years or so I've been into diesel VWs, I've often heard about how sensitive the turbos are and look at 'em wrongly and they may grenade, destroy the engine ,and half of the village....

Well 2 years ago, I had a headgasket go, so I skimmed the head by hand and removed the 6 thou variation [and probably more flesh than I should have done, as since then I've had piston to valve clash-apparently noisy but harmless ].
Anyway a week later, I'm driving up our town bypass and suddenly there is a dull 'thunk', and the car slows down to a crawl, does not stall, but wil not accelerate. I get round one of our particularly nasty 'roundabouts'   with about 10 cars breathing down my neck , and I'm just able to mount the kerb and pull off the road.
I lift the hood and start fiddling:
 Pulling on the pump lever slowly raises the speed above idle, but nothing more. I unclip the filter thinking maybe it had blocked somehow and found I'd left the filter out .
There is a funny low pitched whistle coming from the intake. I pull off the hose to the turbo and find it rotating but looking 'white'....



Turning off the engine I found I had sucked in a couple of sheets of paper towel
Pulling out the impacted paper, I found that I had done no damage that I could detect. Two years on and it still works fine.
Due to the oil consumption up till last August when I reringed; this car has only ever been run on 30W 50 multigrade.
I now have to change the multigrade once a year, rather than keep topping up; so my soft drink bottle cylinder abrade has been successful as far as I can tell

[Fredrikkk]

I'll make sure to prime it!

And that is one hell of a story! Haha I'll have to make sure to be careful about paper towels when I install

[Fredrikkk]

Well, I picked up the turbo, and luckily it came with the intake hose and the oil line. I only have to make a new return line
