2.7L Turbo problem

[jexhed]

Located in Rockingham , WA and currently having a problem with a 2007 D3 2.7L blowing smoke. It has been to a diesel mechanic , Tickles Discovery Automotive in Wongara to have it analysed and they say it is an intermittent turbo problem. An electronic part that can't be replaced requiring a complete turbo replacement. I have done a search on the forum and found some topics back in 2010 which indicate parts were not available back then so I assume they are still not available ? Does anyone have an update on these turbo's ? Does anyone know what model turbo is used on the 2.7L as the numbers are difficult to see on the actual turbo ?

A common fault is the turbo vane linkage partially or completely siezing. It can be lubricated and moved by hand to free it. This may not be your turbo's fault but worthwhile checking that the linkage moves freely. There are several threads on here relating to this fault.

Thanks M8. I just need to figure out how to get to the turbo ?? not much room around the V6 ??

[Graeme]

The actuator arm can be seen through the left front wheel arch. Once you know where it is, you can get your hand down from above to give the joint a wriggle. IIRC if someone switches the ignition on then off you should see the arm move during the cleaning cycle.

some good info on the disco3.uk site relating to this and how to access the turbo vane actuator arm.

Will send a PM,dont want to break name and shame rules.

Following from Jexhed earlier query, does anybody know what model/part number is for the Turbo for a 2.7, and whether there are any aftermarket of such manufacturers that fit?
Any Australian suppliers?
EG: Do Garrett make one, or do the turbo's from 2.7 Falcons fit?

Figure the stealers will want rather a lot to sell me one with LR on it.

Part number is LR021042.

This search of britcar shows 4 options for LR, OEM, Borgwarner and PR2 Garret at 4 different price levels:

Went on a UK LR parts site to check Turbo prices.
They had 2 listed, Garrett PR2 at approx $1700 and LRGarrett PR2 at $4350.
Figure that likely the GarrettPR2 can be had in Australia at same or less than UK price, will just have to keep looking.

Put a product called "Revive" through the intake. Seems to be ok now, maybe it helped loosen up the actuator arm ?? Found some oil residue at the intake connections to the turbo. Is it recommended to fit an oil catch can to these engines ?

I've used Revive on the tdv8. It made it run smoother and improved power, not that it was rough or lacked power. I was concerned about too much black smoke on acceleration.

[jexhed]

Can anyone explain how "Revive" works ?

Interesting..... when they say locks onto carbon and soot... I wonder if they mean just like water does, ever noticed how clean piston tops and valves are when taking a head of an engine that has done the gasket and allowed coolant into the pistons. haha I'm sure its more than that, but bet its based on that though.... water that is.

Non the less a good idea if it strips off the carbon from the variable vanes on modern turbos. While using other products such as intake throttle body cleaner on petrols is fine, its a bit nasty and a no no to use on most modern turbo diesels.

It's not solvent based. I think it's water based.

Many years ago I knew a person who occasionally gave his old Peugeot a clean-out by dribbling water down the carby with the engine at mid revs. Lots of smoke produced early in the exercise.

[ozscott]

I had a rudimentary vacuum cold water intake in a hot holden 6. Worked well. Cheers

[justinc]

Yes a Squirty bottle of cold water into su's on a rover 3.5 at operating temp and 2500rpm cleaned/decarbonized pistons and chambers well. Can be a bit smoky/ steaming to start off with☺

Yes, exactly what my father used to do on a Morris 1100 when I was a kid. He worked at BMC and also got hold of a decoking fluid that really:eek: created a smoke screen when he used it. You literally couldn't see behind the car for several minutes after you drove off.

Pre pollution days of the Redex 'decoke'!!

[DazzaTD5]

Well thats pretty well agreed... its glorified water..

To be fair though, got to give credit for someone revamping an age old trick, its prolly more idiot proof if following the instructions and hey if it work (no reason why it shouldnt and a few here have used it) great solution.

Our spannerman at work cleaned the MAF sensor in my work ute the other week.He is one of them blokes who knows everything.Anyway he dosed it up whist it was still connected to the hose/turbo with brake cleaner.I pointed out that that aint good you need to remove it,a few of the other blokes were there to witness it.Anyhow he started it,wow it did some big revs and blew lots of white smoke.It didnt blow,but I had a smug look on my face.Told him next time you will remove it to clean it:):):):):):):)

Gave it a try on my 2.7 D4 to try and de-coke the EGR valves as they were sticking open. It seemed to work and an additional benefit was cleaning up the variable vane turbo.

Recommended it to my mate who has a 3.0L D4 and it certainly removed a lot of soot and coke during the application. Took it for a hard drive and it poured smoke for about 1.5K's then settled down.

As he had a Defender with an after-market variable turbo - we cleaned it up too so all is now good for the fleet!

BTW - I've since had the ECU reflashed with the EGR software mod as I was shocked at the price LR quoted to replace the EGR valves. It was cheaper (And permanent) to reflash the ECU!

I remember learning that a water hose squirted into the intake of a running gas turbine was used to clean out the carbon if regularly run on diesel. Understood also that the O2 in H2O gave a slight performance boost in the right dose.

Having just done a long trip to Melbourne and back I note that I can produce no black smoke under acceleration anymore. I was hoping that the turbo and EGRs were better for it.

[jexhed]

Well it seems the smoke problem has returned so it may have only been a temporary fix. Water in the intake has been known to punch a hole in pistons as water does not compress.

Hence why many WWII fighers used water injection for emergency power boost . . .


Oh Farrrr# I have a 190 on my tail!!!! :eek:

[shanegtr]

The gas turbines that my work uses has a feature called "Sprint" where they use a water spray in a fine mist in the engine. However its main purpose is to cool the intake air which gives more power and efficiency.

[PerthDisco]

I had not heard of water injection into the Merlin. The 'secret' that won the war and gave the Allies the edge over the Germans was the development of high octane fuel (from the USA). The Germans only had access to poor quality oil reserves. The Merlin got huge hp gains / high compression / supercharged etc. The go-fast button on the stick I think allowed an engine life of 8-minutes. Handy when a Stukker was on the tail.

Well this Disco has been at Tickles for 6 weeks and finally a result. It has been a saga. The first diagnoses was a faulty turbo. A new turbo was imported from the UK. Body of to replace. With the new turbo, still not resolved. They then found a crack in the intercooler. This was replaced, still not resolved. EGR's were blanked , still not resolved. Next diagnoses, the new turbo was faulty so they suggested putting the old turbo back on. Old turbo re installed, still not resolved. Information sent to the UK who replied to say a turbo fault. For some reason, I am not sure why, they then removed the cat converter, problem resolved. It seems the cat was blocked the whole time. It was suspected at first and the joint where the cat was connected was disconnected but the cat was not removed when testing. $4,000 later, now have a disco that pulls like a train. It could have been fixed with a new intercooler and a $10 piece of pipe welded through the cat if diagnosed correctly in the first place.
I hope this post can help others in future who may have a similar problem.Now have a brand new turbo for sale in anyone is looking for one. pm me.

To those that gave used revive on the 2.7, where did you actually inject it? It states before turbo inlet. Having intermittent problems again with the turbo fault. Added 2 stroke oil helps it for a bit but still an issue towing.

I sprayed it in where it is marked on the photo. Be prepared for a LOT of smoke. Someone stopping because they think the vehicle is on fire amount of smoke. Not something you want to do on the local street.

The revive stopped the fault for normal driving but not for towing. Since using 2 stroke oil I have had no more faults when towing. Using the GAP tool the boost pressure actuator is moving smoothly again.

One litre of 2SO for the first 4 tanks then 300ml per tank after that. Have you tried freeing the actuator. This worked for a number of years before using 2SO.

It might be worth checking the turbo intercooler for damage. My 05 Disco was smoking and we found a split in the cooler was upsetting the fuel scheduling. It may be a cheaper fix than the turbo!

[Bazzle21]

I'm still in the air on a 2006 Discovery 3.project vehicle. So i read these posts with interest. It appears to be an expensive fix with multiple issues. Would not a good scan gauge show a fault with the cat , (i would assume over pressure ) . Its a learning curve . Baz
