Hi All,

Last weekend, I was driving down my Peugeot 407 2.0 HDi on motorway engine lost power, loads of white smoke came through exhaust and then car wouldnt move. I had driven around 50 miles without any oil or when the problem kicked in, it drained the entire oil. Engine would cut off as soon as gear is engaged (automatic). Tried starting next day morning but engine struggled and wouldnt run for long, just for 10 seconds max then cuts off. Grey smoke with unbrunt diesel smell. Tried second time, didnt start at all. Tried again today morning, lasted only for 10 seconds and cut off. Second time didnt start-same again.

Could this be:
Blown turbo? (turbo failed engine still would run but car wouldnt move - please correct me if I'm wrong)
Blown headgasket? (engine wouldnt start due to lack of pressure in the combustion chamber - please correct me if I'm wrong)
Or any other mechanical faults?

Any thoughts would be higly appreciated.

Cheers

Thanks all smile

Well(Im not gonna jump into it), I didnt check the oil level before I set off (now I know how daft it was) and yes yes yes....I did drive 50 odd miles. The engine could have had oil in it and the problem burnt them all? Theres no oil leak what so ever.

Sorry I forgot to mention that part. I hired a recovery truck to get the car home and next day I did top it up with oil- yet didnt start. Now when I try to accelerate, it wouldnt accelerate.

I want to try to fix the problem by myself. For that I want to know where to start from.

Cheers

How about a blocked EGR or fuel pump or injector or plug? Engine sound is bit louder, more like theres is a leak in the exhaust.

From my ananlysis, engine wouldn't run for more than 10 seconds. So lack of fuel/air supply?

An update:

I jacked up the car and went underneath. The turbo unit is leaking black oil and couple of bolts and nuts missing in the bracket. It looks like the garage guy did a cowboy job. From all these I think I can confirm I need to repair/replace the turbo confused

I thought I'd cut the cost buy taking it off myself but it looks like no way I can access it from the bottom. No enough room on top. Moving the engine forward to access turbo by removing the engine mount- might knacker the AC piping?

Any advice? smile

Just a quick update guys....I managed to take all the parts around the engine, unmount all three mounts and pull it forward (tilted it more likely) and exposed the turbo. I subscribed to Servicebox and downloaded the turbo remove/refitting manual for this. By now I can say that turbo leak has sent all the engine oil into all the hoses, intercooler and even into the air intake unit (God this is damn serious).

I think I would need two more weeks to get the car sorted. Oh well!

SOLVED!

It's been a year since I managed to fix the car by myself *PHEW*. I thought I'd update this thread. Before I stated any work on it, I spent like a month reading lots of threads and having a word with local mechanics and cab drivers. The work I had carried out below is a combination of all the opinion I got from them..

Actually I hadn't driven the car without engine oil. It had very dirty oil and that knackered the turbo bearing, sucked oil into the air inlet, intercooler and combustion chamber! Because of this I coudln't start the car at all. Few of garages advised me to replace ECU/injector/fule pump etc.

Works I did...
. Sucked the engine oil out of cumbustion chamber using 'vaccum oil extractor, which I got it from Ebay - http://www.ebay.co.uk/itm/4-Litre-Petrol-Oil-Fluid...
. Sprayed 'carbon cleaner' liquid (more like foam)into the combustion chamber and sucked it out after letting it soak for a couple of mins
. Got all the pipes, air inlet manifold and inertcooler cleaned through a local radiator engineers
. Gave the turbo to a local turbo remanufacturer, got it repaired (Á £250) and put it back - turbo removal was a nightmware job!!
. Flushed the engine - few metal particles found in the sump

Left the car untouched for a couple days and gave it a try starting it. It didnt start, kept trying for about ten times and eventually it did start *YAAY*. Took the car for a spin but it was very slow, had a power loss. It's been like this for a day or two and then it started its normal runnig....no more issues afterwards.

Hope this helps

Zak
