have I blown my turbo?

[RobMorris]

Hey guys
just got home from work and after 10 mins driving (so the car was warm)
i stuck my foot down to take over a truck and whilst overtaking i heard a metallic 'crack' and then i lost power...

no smoke and no further problems?
no overheating
just loss of power.. i no longer get the whoosh of the turbo..?
Did I blow it?

 

[RobMorris]

and am i safe continuing to drive it?

The last time a turbo blew on me it was on the M1 and it emitted the most wonderful blue/white smoke that I've ever seen.

So I'd be surprised if it was that.

Maybe the intercooler hose has popped.

Agreed Does sound like a loss of inlet boost pressure.

 

[horgantrevor]

could just be a torn inter-cooler hose would you believe ii just fixed one today on saab

Is there a reason no-one on here even looks at their car before asking what are impossible to answer questions?

Possibly because they would not know what to look for or where to look or just for some reassurance?

Open the bonnet. It's a really good place to start. Lots of bits of metal and loads of oil everywhere...turbo's blown up.

It's a bit like sitting an exam without even taking the syllabus.

So they are impossible to answer questions but you have the answer?

That crystal ball must be well polished

 

[Dieselman]

and so would the many O/p when they opened the bonnet and have a look.

Does nobody help themselves with anything any more? Aren't people always moaning that we are over cosseted nowadays....

...Hmm...maybe not...

I guess people panic a bit sometimes and they post what is really just a call for help. However I can see what Dieselman is driving at. Its extremely difficult to diagnose a problem---- at a distance--- with very little information or visual clues. The more information a poster supplies- model , year, engine chassis number details of the problem etc ----pictures are especially valuable--- the more likely he is to get an accurate diagnosis. If someone only posts the engine went bang an appropriate reply employing the same level of detail might be -----your car is broken?
Having said all that---- I think the general consensus is a blown turbo hose but without hard evidence it will remain an educated guess.

Have a shufty round the engine compartment Rob and look for anything that looks wrong-- then take a picture and post it on here.

But as I said some would not know what they are looking for or just want reassurance and advice from members here before speaking to a garage. After all this is a forum where we are supposed to help each other and share knowledge is it not?

Until the car is looked at by someone mechanically minded you don't know. Its not a complete engine failure as the car was drivable, so its not like a piston has exited the clyinder or a time chain giving up the ghost.

On a diesel car my next guess would be the turbo, or the injection system. Given the lack of turbo noise, I'd be looking at that, and getting the car recovered to a Mercedes specialist to look at as the job will beyond most people....

Failing that, move onto the transmission.

If you were sitting in your house and heard a big bang from upstairs would you:

A. post up asking what it was,
B. post up asking if the roof had fallen in,
c. take a look to see.

OK you win grumpy old sod of the evening, no one forces you to post sarcastic repies either.

 

[Dieselman]

Back to the O/p...

It's a 300TD so definitely no turbo blown, most likely is a either a split rubber bosted air feed pipe or the pipe up onto the underside of the intake manifold has blown off due to not being bolted on properly (read stripped thread).
An outside chance is the intercooler has split, but unlikely.


My money goes on the stripped thread as 300 virtually never split boost pipes because they are made of decent stuff.

Having a quick look round the engine bay should reveal all.

Was that answer C...?

We are a friendly forum and invite members to post question about, well pretty much anything goes really.

Engines have long gone past a set of spark plugs, a carb and a couple of filters.

Be ye not so scathing of someone just wanting a bit of info or best feel! The OP asked an opinion perhaps girding up is loins when all garages are shut.

Just seen DM'S post 17. Not such a grump after all.

John, you are correct, however there appears to be an increasing trend for people to ask before doing anything at all themselves.

With a little input most could answer their own questions and if not would have proper queries to ask.

If it was my car the question would have read something like....
I was driving along and after giving it everything heard a pop and the performance dropped off.
I had a look under the bonnet and saw a pipe lying loose.
Can anyone tell me what it does and how it attaches back on?
