There are not ordinary steel nuts,you can ask for nuts for trubo(high temperature) applications.
For example, http://midnighttouge.blogspot.gr/2013/05/t...-your.html

2008 Defender 110 BMW M57 3.0 Diesel XS CSW Auto Santorini Black

Hi Landy Andy .. Sorry for the late reply

I did as Fatman explained, but was on my own so went a little further to give some more slack. I removed all 4 nuts to loosen off the exhaust, removed the top brace and the bracket from the cat to the engine block from below. This gave me a little more movement. I have silicone hoses so decoupled the lower one to give more movement again. I also removed the air intake pipe and elbow. All easy enough. This gave sufficient movement to pull (with a bit of levering) the turbo off the manifold and replace the gasket.

I wasn't a difficult job .. 700 miles later and still quiet

Carrotbay is right,i forgot to mention that i(the puma i mean

) don't have a cat,if yours have a cat its retained next to the oil sump so its better to undo all 4 bolts fom turbo to cat (15mm size) to gain some movement.
Apologies if i mislead you

2010 Defender 110 Puma 2.4 SW Java Black

Hi guys,

Had the same problem on my def after fitting a decat, a big whistling sound as soon as the engine gets hot (temp needle in the middle range).

After investigation and Defender2 helpful posts have been able to see the problem. the previous owner or LR didn't tighten one of the manifold to turbo nuts at all (few millimetres out). After fitting the decat the wheight of it or just the manipulations around the turbo made the gasket move or split (see picture below) "ergo" the whistling. So idiot as i am i tried to tighten it, but with the time and temperature the bolt got old and fragile so i broke it....I had to remove the whole turbo, replace the nuts, bolts a few gaskets and fitted the Nakatanenga gasket. Now it's all gone, the decat is on and no more whistling.

the original gasket in bad shape

Thanks for your help with the forum..

Cheers

Timely resurrection of this post, as I'm doing mine again at the moment.

Bloody crappy Ford quality, hoping the decat will help with this, so not have to repeat again. .

Hi

After changing the gasket a couple of times (including having to replace a Nak one) I used some 'turbo paste' the last time with the gasket and haven't had a leak since. I'm assuming I have a small warp that this deals with.

Worked for me.

2011 Defender 110 Puma 2.4 SW Baltic Blue

well...
I finally gave up, removed the turbo and ground both the manifold and turbo faces flat. Since I have had two Nak gaskets and they both deformed outwards along the thinnest edge, I also made a heavy-heavy-duty one out of 3mm copperplate and annealed it. The design is basically the same as the Nak/original but curves outwards by about 10mm along the thinnest edge and 5mm along the others (like a bulging triangle). The gasket also protrudes inside the hole by a couple of mm on the thinnest edge. The colder copper outside the joint helps the copper inside not to distort. It's been okay with a big-ass turbo for a few months now (but I will never hold my breath)

p.s. and I have fitted a temperature gauge in the turbo and don't drive like a loony any more

Tell someone you love them today because life is short.
But shout it at them in German because life is also terrifying and confusing...

Matt
As i am still waiting for those manifold gaskets to arrive (almost a month

),i am taking my time ..digging the escape tunnel with a spoon...sorry i was meaning hand filling the turbo and manifold faces,no hurry at all,either way in a year i'll be doing the same again

or maybe this time i'll use original parts(gaskets,studs and nuts) in order to have them fail first
