It's exactly the opposite situation, as the manifolds crack from continual flexing from boost pressure expanding the manifold. They crack along the edges where the flexible sides meet the more rigid edges.
Thanks, hadn't thought of that.
Can see why they crack where they do. The corner would be flexing a helluva lot.

He should order it from the U.K, I ordered 2 Thursday last week, and they are currently sitting in Amsterdam which seems to be the big delay with freight at the moment.
Back in the ye ol days (pre covid) freight was leaving direct from Heathrow airport to Perth airport, order Friday here at the workshop Monday.
The English guy on YouTube who has fully rebuilt 3.0 diesel engines in some very nice videos reuses the HP injector lines and comments he has done so without trouble against the suggestion they are single use only.
There are some good microscopic photos of the crush of the fittings on a new fitting versus a reused one I found online (from someone selling new fittings mind you). I don’t know how real it was. Their argument was that while it didn’t necessarily leak, the orifice is crushed further reducing flow. That said, at the pressures we’re talking and the flow, I can’t imagine it’s a real issue.

I used new ones on the injectors but didn’t replace the balance pipe or the fuel pump feed as they were too hard to access. I didn’t have a problem back then.
The injectors can be refitted at a different angle which compromises the already-crushed seats whereas the balance pipe and fuel pump feed pipes go back in the same position.
A good demo of the fault and location and oily contamination and difficulty of access

James (my MY12) - has clocked over 210k, SDV6 183KW version. No significant issues to date, service most things myself bar the chain etc.
how would I know if I have a cracked inlet manifold? I don’t have any fault codes but I’ve always had a small amount of high pitched whistle which seems to roughly align with when the secondary turbo kicks in. Been doing this since I purchased the disco 5 years ago.
Are the any pre-emotive signals that the inlet manifold is cracking, or any vehicle ago it should be replaced at as a matter of course?
cheers.
No warning when one lets go, just either a pop and loud hissing or just the hissing. Usually under load as the manifilds are then under max pressure.
Car then goes into limp mode, the "restricted performance" message and red triangle comes up. Still driveable, just no real power.
Error codes are usually around loss of turbo boost pressure or manifold pressure.
That other whistle you mention is the turboes spooling up, the primary not as loud as the secondary in my opinion, but then mines got a safari rai, and the inlet sites just near the drivers window making it more audible if the window's open.
Thats a good point, also unless you marked them they wouldn't go back into the same position .
There is no way that flow would be compromised re-using as the sealing surface is external and not internal, i re-used all mine and only had issues with one which was fixed by loosening the injector end then tightening at the rail first.
