Hi all can anyone help/Advise. On my way home on the motorway tonight came off and drove up slip road and i noticed no power, went to pull over, looked in rear window and could not see anything .........She was smokin and a mean smokin, turned engine off and engine continued to tickover, then ran up to about 1500/2000rpm then down to tickover (repaeted this several times) and by now motorway roundabout at standstill!!! I have never seen so much smoke, clearly running on oil. It finally stopped and i was lifted home. When i got home i pulled the turbo inlet off and loads of oil in there, checked turbo for play in shaft and well lets just say the shaft was hanging down (snaped). My question is new turbo, obvisiouly but before i fork out for new, how can i be sure of engine condition before commiting. There is about only 1/4 of sump oil left and i'm to frightened to attempt start. Any advice would be welcome,Cheers Mark

Take the air filter box apart. If it trys to run on after starting up, jam a rag/towel etc in the air pipe. If it can't breathe it can't run.

Cos he dint say if it was a manual or auto and cos the chances are that he'll be wanting to see what's going on within the engine bay.

Could always put the missus in the drivers' seat. Mine has no problem stalling whether she's asked to or not!

If a turbo goes, it makes a LOT of smoke, and the engine will be very underpowered.
Not sure on the "running on oil" situation with a blown turbo, thats "Normally" a sign of leaking injector seals or a craked head and diesel getting into the oil. Have you checked you oil levels recently ? has it been "increasing" on its own ? does it smell of diesel ?

To explain better:
If enough engine oil gets into the engine inlet, from a broken turbo, the engine will run on the oil as a fuel.
If that is the only problem, then it is just the cost of a new turbo or an overhaul kit plus oil and filters.
The other scenario is where the common rail injection fuel chamber in the head cracks, and starts pumping neat diesel into the sump. This eventually gets the oil level up high enough to cause the very thin oil to flood the rings, turbo seals and crankcase breather and the engine runs away using the diesel/oil mix as a fuel, quite spectacularly sometimes.
The only way to stop the engine is to block the inlet, and it is a very frightening thing to do when the engine is screaming away in front of you with clouds of black and grey smoke swirling around.

would be a good idea to remove the intercooler bottom hose and get as mutch oil out the intercooler as you can be greatfull it only whent up to 2000rpm they normaly rev to destruction
Hi all well took turbo off and removed intercooler(full of oil) and inlet manifold,taking sump off tomorrowry and see if anythings gone in there. I am gonna clean all parts, connect it all back together with fresh oil and filters, some how by pass the turbo oil feed/drain slavingthe nakered turbo on just to connect exhaust, run her up then emtey all all oil, clean parts again and bolt a brand new turbo onfresh oil and filters again and hope for the best. If it doesn't work out then i'll be trying to sell a just second hand turbo !!!!!! with less than 10mins on it. Island 4x4 gave me the best price on turbo along with a firm called midland turbos. £440 all in
Hi again, cleaned all the bits and taken turbo to bits . I want to run engine with clean oil and somehow slave the turbo exhaust side up by putting blanking plate on turbo and thus just using it to complete connection to exhaust. Air inlet side will just be open but what i want to know is should i connect the turbo oil feed pipe to the turbo drain pipe or should i blank off. I should stress this is just to temporilly run engine to check all is ok before outlaying lots a money for a new turbo etc. Look forward for your response Cheers Mark
