Am I burning oil...blueish smoke when cold, seems ok when warmed up but need to check.
Sounds like classic oil burning symptoms to me...engine or turbo though?

check your sparks first. if it's engine I believe they should be dirty. otherwise turbo?
Recently replaced the spark plugs...forget what type though, perhaps that could be a cause, but will whip one out and look.
Turbo - I think it's been blowing oil for a while so hoping that is the cause and not engine wear Still got a rebuild kit to play with...
...but I'm enjoying driving it soooo much!!!

More news....for the past two days the car has been very smoky (more whitish now) until the temp gets near 90 and then it's fine! Idle is a bit erratic too, but I cleaned the ICV recently.
Water temp sensor was replaced a while ago but I'm thinking it might be knackered! Does anyone know the resistance values offhand, to save me searching?
Either that or the HG has gone

Found them...
Temperature - Resistance
-10 (+/-0.5) = 14.66-18.84
+20 (+/-0.5) = 3.4-4.13
+80 (+/-0.5) = 0.34-0.42

@ wrinx :
what's the HG?
If it's the turbo, you've said "Still got a rebuild kit to play with..."! So, there will be plenty to mount it?

Sorry, HG = Head Gasket. My theory being that is was blowing water until warm, cracked head or gasket.
But, there's a video on FCCUK which looks similar to mine and had a blown turbo
This is the video, mine's not as bad though http://www.freepsp.co.uk/Car/Marea/F...blownturbo.mp4

mmm that?s a lot of smoke....
Seeing the color could be either from water as from oil, check levels of both.
I?d bet it?s oil and from turbo, didn?t you recently raised boost pressure?
I did...and I also think that's why it's died. The boost never got much about about 07.-0.9 with the PV. Now with the MBC it's up to 1.2 and has obviously been the finish for the turbo This smells a bit oily too...oh well!
I'm losing a bit of water too but from the old radiator!
The car is being retired soon for some extra work so I'll add a turbo recon to the list!!!

That is a lot!! Wasn't expecting it to be anything like that!
Turbo rebuild time then

Now also got smoke coming from the join between the turbo and downpipe...oil leaking oil and burning off.
Think it's pretty dead

Would all this oil near the intercooler connection be linked to the oil blowing turbo....or something extra?
...also replacing the radiator so only need to strip the front end once!!!

probably from the turbo, the airflow slows down a bit in the intercooler, and the oil vapours condensate again aswell...
Removing and flushing through the whole inlet might be a good idea now

Yup, that's what I was thinking too Read on FCCUK about a guy with a blown turbo who suffered from smoke after replacing it, because of the residual oil
How do you clean an IC?
:sigh:

Forgot to ask...does anyone know a supplier for the plastic trunking which covers the wiring? A lot of mine near the radiator/fan is old and falling apart?
Found this stuff... http://cgi.ebay.com/ebaymotors/ws/eB...m=270278586477

Petrol is quite a good cleaner. Take the intercooler off, fill with petrol, swish around, pour out old petrol - repeat until it comes out the same colour as it went in.
Thanks guys, will whip the IC+piping out and give them a dowsing!
