Exclamation alfa romeo 159 2.4 jtdm

Morning,

Yesterday I was pulling away from traffic lights and somehow one of the black hose which comes from back of the engine I think it's an oil catcher or breather and all oil was pushed under the bonnet all over , car instantly lost power and turbo boost. Any ideas why did it happen. will go to get oil try to fill up and start the engine. Engine has a remap de-cat dpf deleted egr deleted swirlp flas deleted.

thanks

That looks nasty!
Keep you busy cleaning for a while
Can you take a closer photo of the actual problem area??

Turbo is dead ... But why oil separator is not separating and sending loads of oil to air intake found half liter of oil in the intercooler . Did anyone had issue with oil separator?

Hvad happened exactly?
It is normal though to have quite some oil in the intercooler because of the condensation of hot oilfumes, that has escaped from the seperator.

If your turbo is bust. Go get the Garrett GTB2056V from the 210 version if you don't allready have a 210.

how has your turbo failed exactly?

im yet to come across an 'old' diesel that doesnt pass some amount of oil through the IC. if its pressurised the crankcase enough to throw that much oil into your engine bay id expect a certain amount of oil in your intake.

the oil separator inhales oil vapour from the pipe leading from the oil filler and from your crank case breather outlet. the oil should then be separated and drain back into the crankcase and the air (in theory, free from oil) is piped back into your inlet, post MAF, Pre Turbo iirc. Although I'm yet to hear of a 2.4 on here that doesn't pass a little oil back into the intake pipework... its a common thing of an oil leak at the inlet flange of the turbo housing. a lot of large diesels generally vent to atmosphere with the odd 1 or 2 having oil separators that are way more effective than any ive seen on cars.

Well, I was pushing hard from traffic lights and just bang loose of power and a bit blue smoke from exhaust, so had to stop and immediately when i stop low oil pressure alarm on dash start to flash so i shut down the engine. When open bonnet oil was all over. right hand side oil pipe came off from separator ant all oil was pushed out. So today i find out that the turbo is gone blades has a massive free play. So I check the air filter found oil in there and oil in the inter-cooler. So my theory now is 1st oil separator failure + turbo failure 2nd because of turbo failure exhaust gas went in to oil system and this cause rapid oil pressure increase and because of that oil separator couldn't manage with extra pressure and that's why pipe blow off and oil was pushed to air intake pipe via oil fumes pipe. And it was 210 bhp when was stock

id be more inclined to say turbo failiure was the cause of your separator pipe blowing off... everything else youve said stacks up though

id also be more worried about the cause of your turbo failure than condemning the 'passive' separator.

so why oil is coming to the air intake now? Can that oil separator fail I'v checked it's not blocked so I hope the turbo failure cause exhaust gas been released to lubrication system and because of that oil been pushed out . I hope ..., and turbo was already noisy...

Sounds to me like oil is being forced past the failed turbo bearings and perhaps the increase in pressure through the seperator has caused the pipe to 'pop off'!?.

oil gets everywhere when a turbo fails

depending on how your turbo has failed you may find the pressure from the exhaust or inlet has found its way into the oil lines of the turbo, upping the crankcase pressure, blowing oil into your intake and then blowing the line off your separator.

whatever has happened youll be needing to pull all your intake off and cleaning it, renewing oil and air filters, cleaning your MAF and boost pressure sensors, will be an ideal time to de-gunk your EGR (maybe a delete?) and have the IC and manifold off to make sure no bits of turbo have ended up in there, also a perfect time to get the swirl flaps blanked/locked/deleted (if you delete the EGR and/or swirl flaps you'll need a remap to avoid MIL and limp home mode).

**IT NEEDS TO BE SO CLEAN YOU CAN EAT YOUR DINNER OFF IT**

Cat and DPF are your next worries, there are companies who professionally clean them, after cleaning them you will need to get the DPF reset with either Multi ECU Scan or pay a dealer/specialist to do it. additional hydrocarbons (oil or excess fuel) in the Cat and DPF cause monolith damage and you'll end up replacing them if they're not already shot by not cleaning them now.

im sorry that you've had one fail and i hate to be the bearer of bad news with regards to the amount of time and money its going to cost you. the only silver lining i can give you is be glad you didnt end up with a 'run away' (where the engine runs on the engine oil after a blown turbo) because then you'd be into a completely seized motor and not just a new spinney boost creator.

I'm thinking to by a cartridge and rebuild the turbo this what was done with my brothers 156 2.4 and it was same as brand new turbo, but i'm interested about variable geometry I think the old jtdm turbines has '' outside geometry'' which is sitting around the blades, this turbine variable geometry is under the blades so as much I understood you cant remove the flaps from the cartridge so I assuming the cartridge should be together with the geometry... So when I open the turbo I found cold side compressor axle broken and ho side was jammed.

So finish cleaning air intake find a bit oil in the intercooler and pipe work waiting turbo parts now, all gaskets and oil been ordered waiting for them as well.

How much power/pressure did this care make before the turbo gave up?

Good HP but low torque.
I was thinking if the speed of the turbine might have been too high

I think it was the time for turbo to go , it was already noisy.

So yesterday I rebuild turbo put back to the car and we are on the road again

And i discovered that the flexi exhaust pipe has a gas leak. Does anyone know where to get that part or what size it is?

Hi, I see your an Essex boy too. So, I saw it an easy turbo to swap? Did you have to split the entire front end off the car, or do I think in situ?

Hi well i live in Essex . yes it is very simple job, jack the car disconnect air exhaust and oil pipes unscrew 4 nuts which attaching turbo to exhaust manifold and you can easily drop your turbo on the floor. Just be careful with car stands your doing this on your own risk

Aha. Ok. Sounds a lot more simple than the GT.

Thanks.
