Wrinx, are you going to use an "original" style radiator - or go for something in aluminum?
any disassembly pics?
jim.
I was just going to stick a "normal" radiator in there, got a price of just under ?120 delivered, which I think is great!
Will post a few pics when I get some more work done...

A few pictures of the progress so far....ok, a lot more than a few, you may want to put the kettle on....!
Grill out
Bumper off
Wiring etc out of the way
Intercooler shroud with the little spray
Oil!
More oil! Intercooler pipe
Not so shiny
MORE oil!
Intercooler off
Intercooler pipe not sealing well either, not surprising there is oil everywhere
This is getting silly now
Oil in the engine bay
Disconnected the aircon...there was nothing in it!
Radiator loose, ready for removal
The worst I've ever seen!
Read on......

After a light rubbing
Someone's idea of a good job
Removed the support panel too, for cleaning and painting
Cleaning the tubes
Lots more room to get at the tubby now
The next job, removing the turbo
The car now, turbo is held on with one bolt...for tomorrow!
The garage...Alfabits everywhere!
I need to go and buy a blast cabinet and lots of paint!!! Planning to refurbish and paint everything that's come off and perhaps the chassis legs while I'm there!
What fun....

If you want, I can blast anything for you. Postage might be on the expensive side though!
Is there any oil left in your sump???

After checking out the price of cabinets I might take you up on that!
Think I'll just get some rust preventer and hammerite the support panel
Least I found out where the oil was going...!

Turbo strip down....
Removed oil pipe
Remove wastegate actuator
Undo bolts and remove cover
Remove exhaust elbow...more oil!
Undo bolts on other side and remove cover...to reveal MORE oil!
Remove shaft and firmly clamp in vice (there's a flat on the triangular centre), undo the splined nut using an 11mm socket (not six sided)
Remove turbine
...and the bit underneath, this shows the underside
Remove the bearing
Remove circlip
Lift off the body
Yeewwww, guess this is contaminated and burnt oil!
What's left
One brass bearing will come out and you'll have to remove another circlip to allow the second bearing to drop out
The turbo in bits

Ohhh, how did they get in there?
I did a phone video of the side play in the impellor shaft but it's disappeared. There was roughly 2mm of sideways movement! Thankfully no float on the shaft but I'll replace the bearing anyway.
The brass bearing with visible scoring was about 0.5mm bigger internally than the new replacements, the other is about 0.2mm...I guess that's where the movement came from!
If I'm posting too many pictures please say so...

One question...there are some spring retainers on the ends of the shaft, how do I get them into the casing when reassembling?

The shaft is ok? No marks on it?
Seems to be ok, there's some light wear marks but as it runs inside the softer (phosphor bronze?) bearings there shouldn't be a problem.
I will check the measurements, but without a spec sheet I won't know if it's within tolerance anyway

I have this kit also, but my turbo is beyond repair when it broke down.
The axle between the both turbines is broken Also some blades on the turbine on the exhaust side are burned away and some broke when it suddely came to an hold from way to many RPM's till standstil
Keep those pictures coming I am also curious for the results after youre done Wrinx.
Greetings,
Marc

no wonder your jtd was faster than the q4
Will you use 360 degree bearings now?It will help the turbo to last longer
great pictures wrinx - umm.. could you weigh the fan and shroud for me if they are still off the car?
jimn~
.. that radiator is the worst I have ever seen - can believe it was on a functioning car!
