SDV6 primary turbo gasket..body off??

[catch-22]

D4,3.0, 2010.

A smoke test was done and the whistle is coming from the gasket between the primary turbo and exhaust manifold, on the left side of the engine bay. The gasket isn't going to cost much but I'm told in order to change it the body needs to come off - 9.6 hours effort.

Does the body really need to come off?
OK to drive around if it can't be done straight away? Pretty sure it is....

Cheers

Recent story claiming turbos can be done once egr plumbing removed as an alternative. Others will confirm but Rovertech Perth doing this way.

I have a hissing induction noise since having a sump off to fix the oil monitoring system.At the same time it went to the panel shop to fix the roo damage to the RH front guard sustained in Exmouth.
Need to get it back to the dealer and panel shop to investigate.It mainly happens when cold,when is your noise worst?

Yeah can hear it more when cold. But cold or hot can reproduce it without load, that is, disco in park and a quick but firm bleep of the acc..when the engine starts spinning up the sound is heard.

I don't like it. I like silence but am going to shop around for a quote.

I just had my turbos replaced with body on by removing the EGRs. One week later on a trip to Shark Bay over the last 2 weeks and a loud hissing and whistling sound started coming from the left side. Rovertech have just confirmed that it is the new turbo to dump pipe gasket and are having to replace it under warranty. Now relatively easy access because the EGR has been removed.


I initially had a problem with the engine light coming on but they fixed that finally after many hours of fault finding. Apparently it was a broken wire on the wiring loom but it only happened after removing the EGR system and installing an emulator. No engine light on the trip to Shark bay towing my 2.2t Kimberley Karavan. Just the very loud hissing / whistling sound under load after I reached about Geraldton on the way up.

Primary turbo to dump pipe gasket all fixed with body on!

G'day Bob
I assume you have a 2.7 D4. How many km on your 2.7 when turbos needed replacing? Do you know what was worn? Thanks

[catch-22]

Cheers Bob. Now I just have to find someone who'll do the job..

See my signature, 3.0l TDV6 D4 2010 (equivalent to SDV6).


230,000km, whistling noise from manifolds and suspect faulty turbos but still working OK. Been the same for about 10,000km.


From factory, no gaskets on manifolds or turbo to dump pipes and all leaking. Both manifolds were warped, especially the left side, which had a broken stud at the worst leak area. Both turbos had bent over inlet side turbine blades as if something had hit them, but not much bearing wear from what I gather. I saw them and checked for play but couldn't detect any.

It would probably only be worth removing the EGR's for future ease of maintenance and if you don't want EGR's. It will probably cost as much as removing the body if they do it in 9.5 hours. Just the EGR emulation and CPU changes were around $1000 without the removal cost of the EGR and it is illegal as I understand it.

I rang Southerns today about the induction noise(well I believe it is).They want it in ASAP for a look see.They doubt its a big issue as it should be throwing codes.
They are looking at it first thing Friday.
Andrew

[BobD]

Andy, on Friday the mechanics thought mine was an induction leak but once driven and with no signs of any black smoke or performance reductions or codes they changed that opinion to an exhaust leak. This is what it proved to be and since it was after the turbo there was no effect on anything.

Mine only has made the noise since my sump off to fix the oil monitoring sensor.At the same time it went to the panel shop for a new RH front guard after a minor roo strike.
It made the noise from the day I picked it up,which was a Saturday,havent been in Perth on a week day with it since.
Off to the Kalbarri area next week camping with the camper trailer so it needs looking at.
It goes away at higer revs speed,pushed it a bit more than the legal limit and it stopped,not wind noise I'm saying.Then put the cruise on at 110kmh and paddled down,it went in 5th/4th gears.So guessing something to do with the secondary/primary swap.Not the HEVAC system,on or off is the same.

Good luck and at least you are under warranty. Mine noise also reduced greatly when the secondary turbo cut in but then increased above that again. It was also non existent when the engine was cold, unlike the earlier leaks when it went away once the engine warmed up.


No noise at all now and no extra cost, so very happy.

[rar110]

Ta Bob. I can't see signatures with tapatalk. I didn't know emulators work on the 3.0. I've had mine on the 3.6 tdv8 for about 6 mths. Going very well.

[catch-22]

Get Land Rover to do a smoke test like they did mine. Solves where it comes from with no doubts.

Mine is not throwing up any codes.

I recon it could be a little rougher but it's more than likely all in my mind.

Cheers Bob, this cars going to remain exactly as Land Rover intended. No mods whatsoever. So a body off it is and all booked in [emoji41]

[catch-22]

Andrew, if it's primary to secondary swap as you suggest then more than likely body off I've been told.

And you probably don't want to be towing with the issue just in case. Constant higher boost won't do it any favours.

[Graeme]

Andrew, if it's primary to secondary swap as you suggest then more than likely body off I've been told.The secondary turbo isolation valve is readily accessible and only takes a short while to remove.

Good point. Was thinking worst case and split pipe, of which I've heard a couple of cases.

[Graeme]

If you're referring to the exhaust cross-over pipe then the 2.7 also has that pipe with its single turbo.

[DazzaTD5]

A few months back I was talking with one of Kev's guys (at Rovertech) and he had said he just did both turbos on a D4 with the body on, mostly only cuz it had a lot of accessories on it, as in bullbar, rear tyre carrier/rear metal bumper.

These items do add a lot of hrs to a job, but when a D4 is stock, I can have the body off quicker than most will dick around with it on. It also means the job gets done neater and less chance of things like a gasket failure.

Quite simply, it should be no skin off the owners nose what way a repairer chooses to do the job. To me its what the mechanic feels more comfortable doing.

Daz

[BobD]

Daz, I think mine was the first, exactly as you said, because it has every accessory under the sun on it and they were worried that they might cause problems getting the body off. I was also glad to do it this way because it makes things more accessible for future maintenance and I was happy to remove the EGR's.


I can't actually tell any difference, either in performance or fuel consumption, with the EGR's removed, however.

[DazzaTD5]

Thats correct, while in theory from a mechanical engineering point of view, economy and power should increase, but as a diesel really doesnt require much Oxygen (as in "air" is not just oxygen) to function, more often than not its quite normal for an apparent no difference.

BUT.... what you now dont have is the exhaust gas mixing with the crankcase ventilation creating that nasty tar like product in the intake. And any built up that was there before will start to clean in as little as 10K of driving, from a engine point of view its just win win.

(and yes this is all but a theoretical discussion as disabling EGR is not a legal practice)

Southerns checked my D4 for the annoying hissing sound today.Nothing loose,no codes generated,no leaks in hoses or the exhaust.
Went to the panelshop,they are highly regarded prestige repairers.The bloke who worked on it had a pretty good look,showed me where all the seals are on the guard confirming that they were all in place.Told me I could book it in for a day in the new year and they will remove the guard to double check.
Now more convinced its a weather seal issue,was very noisy this morning with a cross wind from the right.On the return,heavy headwind,the noise was barley noticeable.The new roofrack was noisy though.It wasn't too bad on the way up.

Andy, it not a Patrol! The doors don't leak air in any conditions!!


After all the time I've had mine and the distances on really rough roads etc the only real source of any funny noise is if the plastic covers on the windscreen pillars get detached by a passing truck and you remove them until you can get new clips.
