Ok so here we go , looking for some ideas here to back up my own or shoot them down as the case may be.

Initial symptoms started a while back started getting a few puffs of thick white smoke on start up but ran fine after.
while on the bypass a few days ago it started blowing lots of the suff and had to pull over. Shut down the engine and got recovered back home.
Tried to start it again but got nothing just a few puffs of light white smoke not the thick clouds i had earlier.

Stripped out the turbo and found it in bits and a lot of oil in the intercooler pipe.
Now im not sure why it would not start up regardless of the turbo being goosed. And turbos dont just self destruct through wear and tear normally.

So what im thinking is i have a few issues .

1. A goosed turbo.
2. possible diesel in the oil which lead to the turbo self destructing.
3. for diesel to be in the oil i injector seals gone which is the good scenario or the head has cracked.bad scenario.

Any other thoughts from the wise , I would love hear any suggestions before i go fit a new turbo . And any recommendations on where to get one ??
Oh and its done 95,000 miles

Thanks

Thinking out loud - someone who knows will be along no doubt...
What made the leap from goosed turbo to 'diesel in the oil'? Does dip stick show this, or guessing?

The bearing was clearly on its way with the white puffs - if its had 95k of hot shutdowns then that could do it? Or other starvation/contamination/just bad luck bearing failure......

Don't think it would start happily/at all with turbo in bits - would be looking for inlet pressure that isn't there and screw the fuelling completely?

New turbo on the cards - and hope there is no other sign of diesel in oil or head probs - short a list of jobs as poss. Fingers crossed. Cheers, A

it will start alright without a turbo
only way of knowing it putting diesel in the sump from o rings or a crack is level on the stick rising
turbos can just fail especially getting near a100k

Turbochargers do self destruct. And it happens quicker if they aren't looked after, wrong oil or revved before switch off.

I would look for positive evidence of diesel in the oil (rising levels), before making any assumptions about seals or cracked head.

I could just be over thinking it. Its hard to say if the oil level has increased but i was thinking that it could be a reason for the turbo to fail , That said there is no evidence of any other damage to the engine (yet). Im at a bit of a stand still with it at the moment till i get my new rear crossmember fitted, I can then get the tank back in and see where we go from there. Fingers crossed its just a turbo but i do have a feeling there is something more sinister lurking under the bonnet. Time will tell .

turbos can fail at any time specially if they do allot of around town work as the turbo sees many cycles spooling up and down compared to a turbo that sees allot of high way driving ..hot shut downs is also a big killer as the housing that holds the bearing can warp and the hot oil sitting in the bearing boils pitting the bearing cavitation

also turbo killers can be to high of EGTS / very bad quality of oil /oil pressure / clogged air cleaners

unsure about the history of your engine but your also going to need to check if oil is in the exhaust maybe its clogged up the cat. when the turbo failed .... thats providing you have one CAT

the engine should still start without a turbo but the turbo needs to removed for this test ..... as its in bits ...your also going to need to blank off the oil supply or divert back to sump otherwise it will get messy

what about those hydraulic lifters maybe there stuck or not seeing a pressure to activate ?
