So eh I kinda killed my car at the weekend.

I was on a long motorway spin on Friday evening and my exhuast emmissions / engine management light came on along with a jolt in the engine and then went off again.

Then it came back on along with a tiny whining noise and a lot of smoke, had to pull in straight away, I turned off the ignition but the car was still reving furiously. Two men pulled in and one of the stalled the car and the other popped the bonnet and disconnect the battery for me.

I never got such a fright in all my life I didn't know what was happening, I couldn't for the life of my understand why the car was running but yet I had the keys in my hand, I was just standing there in shock watching and waiting for it to go on fire 

So I now know how to stop a runaway car and how to kill a turbo 

Himself was working on the car last night, the turbo 100% wrecked but going to pick up a second hand one tonight along with a manifold.

He has drained 3 litres of oil from the engine, no signs of any metal in the oil so I am hoping that is a positive sign that the car was stopped manually before it stopped itself by running dry of oil, the service done the week before had to of saved it perhaps since she would have been full?

Is there anything that we need to be looking out for before the new turbo is fitted?
From what I have read turbo's don't just go something causes them to pop?

I think the service may have put the car into shock  I doubt an oil change has been done on the car in a very long time, I like to take on challenges but took on more than I can chew with this little (big!) project!!

The car still starts, we were able to get it started to get her on and off trailer but naturally of course reluctant to leave running any length of time with the broken turbo, he said there was no bottom end rattle in it, I dunno much about cars but I think bottom end rattles are badddddd

So Omega ownership has most definitely started with a bang

Sounds like a classic diesel engine runaway, probably due to failure of the turbo's oil seal and ingestion of engine oil which is what continued to fuel the engine. I would be investigating any other areas where the oil could have got in just in case. Breathers might be a possibility, but I'm not that familiar with diesel engines.

The question is whether the engine has been damaged. It might well have been over-revved in the process, but the fact that you stopped it before it seized gives some hope.

I think I'd be looking to run it up without the turbo connected to the intake just to ascertain if the engine sounds healthy before spending any money on fixing it. Keep a pile of rags handy that you can stuff into the intake and block the air supply if it takes off again, though!

The other component that could have suffered during this process is the clutch, of course.

Stupid question but can you explain the reason why to me I am sure it's very simple and I will feel stupid once you explain it

[Kevin Wood]

As the clutch was effectively used to stall the engine running at full power, it might have got quite hot in the process, which may have glazed the friction surfaces. I guess you can only really assess that once it's running again, though.

[Fiona]

Ahhhh I see.

Oh well sure fingers crossed, have a second hand engine sorted as well for decent money if we need it. I hate cars* 



*said no one ever!

Make sure you clean all of the intake pipes and intercooler of oil build up inside them,seen turbo's replaced and first good rev up the engine takes off again as the oil in pipes etc is blown into the manifold

The clutches can take a fair amount of abuse in isolated doses

[Gaffers]

Is that with or without TC on

was actually thinking of Joshs' black saloon which to a bit of a hammering whilst rescuing a stranded damsel in a Porsche Boxter...

Check the intercooler for oil and the exhaust or you might find you get a lot of smoke on start up and the oil may of collected in the silencers on cooling

[VXL V6]

Very occasionally they damage the camshaft when they've run flat out on their own oil.

Obviously you'll find out when you try and start it.

?? see reply #5 above

[Fiona]

Went and looked at a replacement turbo last night, there was no play in the shaft but the turbines were damaged on it so himself didn't want to risk replacing it with that. The search continues!

[Marks DTM Calib]

Must be plenty of them around as there a rare failure plus there are pretty common Garett GT1849V with minor variations so they fit.

We found out last night that Frontera turbos will fit so think himself might have sourced one so fingers crossed, they are not that bad to buy from new €350 I was expecting them to be a lot more, to recondition them is approx. €300, for that price would you not be better off just buying a new one instead of getting old one fixed
