Technical Breakdown

X2/50 2008 with 2.2 engine.
Oil consumption started increasing from next to nothing to maybe 1 litre in 200 miles.
Then pulling hard up a hill suddenly lost power, lots of smoke so had to stop.
No warning lights on, checked with code reader, no fault codes, and only thing visibly wrong was the smoke. By this time it had cooled a bit, got it started to get off the road as in a dangerous position. Managed to get to a place of safety but engine was revving up on its own without the throttle being pressed
Let the clutch up and stalled it before it over revved.
Now it will start with difficulty, and tickover with foot off the throttle, and can be driven enough to be moved a bit, whilst still running very rough producing lots of oily smoke and very little power. No undue mechanical noises.
Any ideas please?

Sounds like the Turbo oil seals have gone, seals start to leak
engine runs on it's own oil till you stall it, it revs it's self to
death or runs out of oil.

Thanks for the reply
I just hope the turbo hasn't blown any shrapnel into the engine.
I've heard something about weak cracked and holed pistons on the 2.2 engine pre 2009. But IIRC thats to do with injectors causing overheating?
And this starts OK considering the amount of smoke its chucking out, so maybe the injectors are ok?
Engine runs worse when its warm than when its cold, maybe because the turbo is blowing more engine oil in when it warms up?
Turbo looks very difficult to get to, especially without a hoist.
But every ECP branch seems to have a turbo for this 2.2 Ford/PSA engine in stock so I guess it can't be very unusual.
Anybody changed one?

If it has done a piston It would likely have a steady miss on one cylinder,
but you could do with making sure I am right before buying a turbo,
Try taking the input pipe to the intercooler off see how much oil is
in there as if it is the turbo oil will have to go through there to get
to the engine.
I doubt the turbo as blown any bits into the engine only oil from failed seals.

Excellent Idea Thanks RalphM
Runs a bit better with one of the rubber air pipes from the turbo to the intercooler removed.
Brought on the engine management light for the first time.
Still lots of smoke and loss of power but no oil dripping from the exhaust as there was before.
No obvious abnormal mechanical noises though.
Sounds almost normal on tickover but obviously something wrong when you rev it up, and it turned heads when driving down the street.
Stalled when I was turning round and I feared I would be stuck there but it started again fairly easily.
Looking at the amount of pipework and the intercooler I can see you are right - even if the turbo was throwing shrapnel I can't see it getting through all that and as far as the engine
So maybe its worth repairing
Be a shame to scrap it - 13 years old but not a speck of rust on the galvanised bodyshell.

If you do go for the turbo try to clean/dry out any oil
in the pipework and cooler.

Turbo suppliers INSIST on new oil feed pipes [ some supply as a kit ] , otherwise no warranty ...!!!
