When I excellerate there is a whistle garage advise an intake of ait through the turbo charger is this likely. 5 yrs old
Turbo whistle is common as it comes from the tips of the compressor wheel passing through the sound barrier and the turbulence occurs. IN the older trucks you would the turbo whistle as the engine reached full RPM just before a gear change. In smaller engine it is not do noticeable as there is an excess of air pressure that keeps the compressor wheel at a lower rpm and the pressure is dumped out. Turbo compressors reach revolutions in excess of 120.000 rpm under full load If it has just started to make the noise then check the intercooler system for leaks--loose clamps--- splits - Have the turbo compressor checked for damaged fins from the ingress of fine dirt from a bad air filter---check the air filter is not blocked as the turbo speed may result from running in a partial vacuum ( no load on the compressor wheel)

Remember, what is heard as turbocharger noise may not be caused by a noisy
turbocharger. Before replacing a turbocharger perform the following diagnosis.
A. If a loud whine or whistle is heard during acceleration
and increases or decreases with rpm and load. This condition is most often
the result of a loose clamp/hose at the turbocharger compressor outlet, charge
air cooler inlet, outlet or at the intake manifold.
1. With the engine running at idle and the transmission
in Park or Neutral with the parking brake set, feel for boost air escaping
at each connection between the turbocharger compressor outlet and intake
manifold. For limited access areas, spray soapy water on those connectors
and look for bubbles.
2. Check the exhaust manifold and exhaust system for
leaks.
I hope this helped.
Thank you,

SOURCE: oil coming out of exhaust and whistling turbo
it sounds like your turbo has packed in firstly the oil seal in your turbo has failed thats why ur seeing oil from exhaust & the whistling from turbo is the vanes in turbo breaking up so i would advise not to use car until new turbo is fitted & inter cooler pipes and inter cooler itself are checked & cleaned for swarf from turbo you can check turbo by disconnecting turbo pipe &inspecting turbo vanes (fins) to see if broken up or any damage to chamber.

Its surely not turbo, its is somewhere a hole or leak in turbo air filter housing or air inlet pipe that is making noises when turbo sucks air. check the air pipes wheather they are fitted correctly. Take a keen look at air hose and close any hole with silver tape check the hose is fitted correctly in Turbo air filter housing (if not then it makes whistling noise when air is being sucked by turbo) . Clean all air filters and then give it a go.

Turbos are noisy if they are working. If you have the 2009 6.4L they (twin turbo) should be pretty quiet unless you have aftermarket items installed. If no aftermarket mods have been done have the coupling joint between the turbos and the outlet gasket checked by your dealer.
If it a 2007 as the heading says the original air filter and exhaust muffle a lot of the turbo whine but not all.

it could be a loose pipe on the turbo. the noise would get louder with higher revs as with higher revs higher boost is produced. check for loose pipes and give them a tighten then try a test drive. hope it helps you
