Bruce, that sounds like a leaking exhaust manifold. Any indication of soot around that area? --

my thoughts were geared towards viscous as it doesn't always do it. the only times it did/does it on mine would be when i would expect the viscous to be locked up, ie post hard work and then heat soak prior to a pull away

if it was an exhaust manifold wouldn't it do it all the time? Cheers

I didn't notice that till you pointed it out. I used it to illuminate the heat shield bolts, if it was the other way around It would light up me instead. Whistle

I've deleted the picture. Thumbs Up

what were your thoughts then leading to turbo over anything else? Cheers

Reason I thought turbo is because of the sound and it only did it under load or under boost and at no other time. When I released the accelerator and accelerated again it stopped. I read the comment about the clutch but it definitely does not come from that area, unless my ears are playing games on me and I doubt its the fan as I have heard the fan come on in heavy traffic.

Now I am totally guessing with this, and trying to think logically, but I believe that these motors run a variable vein turbo.....I am just wondering if perhaps the veins get "stuck" in one position after a long trip under constant load causing the sound and then release themselves when cooler or asked to work at / stressed at different levels. (hope that makes sense)

Bruce you can check the control bar between the modulator output arm and the VV control arm. Both ends of the bar should move and it will feel quite loose, there should also be some side to side movement of the bar and both ends should have grease on them. Though I can't see this causing the sound you are on about Confused

Doesnt do it any other time. Only when I have done a few hundred kms of highway cruising.

It definately sounds like its related to the turbo.

Any ideas what it could be?

(its a MY11 Puma 110 with 37k kms on it)

Thank you


Finally what was the problem, did u fix it? I have exactly the same issue with my 2014 double cab.
Tnx

Yes eventually after being told many times that nothing was wrong, i insisted that Land Rover remove the exhaust from just below the turbo. When they did that they found that it had been leaking at the joint. Never had a problem again. "Overlanding With Bruce" - Youtube https://www.youtube.com/@OverlandingwithBruce

Thanks all for the above comments. Think I have this problem with mine. Sounds between a scream, and a whoosh noise but only when hot and whilst accelerating hard, like pulling away.
