drove car with blown turbo
Discussion
hello guys i purchased a car from a private seller and then 3 days later the turbo blew up i drove it for couple miles i was wondering if i damaged any other parts of the car? The guy that recovered the car to my mechanic said their is oil leaking under the car? Hopefully i did not damage anything else by driving it for couple more miles i was driving it very gently
How long is a piece of string?
It all depends. Did it run out of oil? Did it ingest a lot of oil through the intercooler and into the cylinders? Did the turbo detonate into many shards of sharp, hard, metal, which then got stuck between a valve and the head? Did any of the metal bits get recirculated into the oil system? It is possible none, some, or all of these happened, but I'd be checking my oil level, and looking at the oil very carefully to see if there are any iron filings in it.
Either way, you'll find out.

Being a diesel, if it ingested the oil it would probably have gone into catastrophic runaway where it burns its own oil, even with the ignition off. Which it obviously didn't do. I wonder where the oil is coming from then. There is only so much diagnosis you can do over the Internet, eventually you have to take it to a local independent and ask them what needs doing / how much a refurbed turbo and fitting etc will cost.

ordered the refurb turbo should arrive on thursday car is currently at my mechanic but he is busy so im gonna get it towed to a different mechanic hopefully it didnt damage any other parts if it did im so screwed Make sure the entire inlet tract is clean,do not leave oil anywhere,make sure intercooler is clear of oil before you start the engine.
If you don't you will have a runaway engine once it goes on boost.
Trust me if it happens you will st yourself.
You can stall the engine by stopping and letting the clutch out with the handbrake on IF the handbrake works well.

it was started today to move the car from a parking spot it stopped fine after so i guess the intercooler is fine?If you don't you will have a runaway engine once it goes on boost.

Incidentally I passed a van with just this problem near Bromsgrove yesterday. Thick smoke for 150m. Everyone stood around waiting for the explosion !
If it's a Ford/PSA/Volvo/Mazda/MINI 1.6 diesel, don't just fit the replacement turbo, or chances are you'll be doing the job again within days. There's a whole list of other stuff that needs to be checked/cleaned/replaced at the same time.

Cat really is about it. Is it diesel or petrol? Don't want it running away on you but doesn't sound like it did. Good flush of the oil after new turbo it'll be fine
Be more concerned about cleaning the intercooler etc rather than flushing the oil. Op needs to take his car to a garage.
When the turbo blew on my 2.0 TDi (Pd140) Audi, needed to replace several breathers and other bits as well.
You could also pour oil out of the exhaust when it was removed, and all the intercooler etc pipework had to be cleaned out.
Its not just a job of replacing the turbo, lots of things need doing.

Or you can just do the obvious and put your foot on the brake - but in many cases, the torque of a runaway engine will overwhelm a clutch and it'll simply slip.Tankrizzo said:
I blew a large piece of wheel fragment out the exhaust of my 306 DT when the turbo went pop, travelled quite a long way behind the car still smoking on the road....
I'm curious as to how a "large piece of wheel fragment" managed to get all the way through the inlet tract, squeeze itself through a tiny gap of just a few millimetres between the inlet valve and the valve seat, get sucked into the combustion chamber, survive a compression stroke without smashing the piston crown and jamming the engine, them make it back out of the combustion chamber through another tiny gap between the exhaust valve and the exhaust valve seat, out of the cylinder port, down the exhaust manifold and out the back of the exhaust......TRIUMPHBULLET said:

Good luck with that if your car is an automatic! If you don't you will have a runaway engine once it goes on boost.
