Turbo sucking noise

Hi Darren
I have A GQ 2.8
You haven't given much detail. Are you able to give any idea where there the suction noise is coming from. is it loow down in the motor compartment, up high etc???? Had you done any work of any kind in the engine bay? Lots of questions but a few details may help to get some responses that may help you.
Mine will make a bad noise if the air cleaner hasn't been seated quite right and the lid is not sealing properly. I have Safari snorkel and aircleaner box.

Mine has the same noise - you can play with the accelerator position and tune it in and out - does not occur under light load
Sounds like it shouldn't happen
Discussed with dealer about 5 years ago - did not have any suggestions
Couds it be restriction in intercooler due to oil buildup?
Would like a fix !!

As you have had work done on the car I reckon it must be something that happen during that work. You have probably already checked but have another look at all the hoses and clamps on the turbo and intercooler. Even though they say they didn't touch them they could have pushed against a pipe and made it leak etc.
Also check the large air inlet pipes and see that they are still firm and dodn't squeeze up when suction happens. this can happen sometimes if they have gotten oil on them.
Again check the aircleaner box for cracks or leaks. Just a few ideas that might or moght not help.
