Its coyotes , they are near by, make sure you build a fire at night.

Sounds like some sort of pressure being released after you shut off.

Blades scraping the housing of the turbo?

[Barra]

Whales mating call.? Bearings in the turbo, does it make any sound if you turn the fins by hand?

[shaneo_1]

nah the sound is coming from back of engine, turbo sounds fine, can here it spin freely after shutting down

[MX Dave]

Is it popping The dipstick out? Could be some sort of Excess crankcase pressure. :/ god that's a weird sound!

[shaneo_1]

Nat dipstick is fine. everything else seems normal. been told there is a sensor round the back of the head. is this right? Could it be leaking

[Dillz]

Leak in the air con lines? Was it on in that vid? Does it work well?

Sounds like some sort of pressure being released after you shut off.

Now you just have to find it. Get a stethoscope and try different locations on the engine and its components.

Its not the turbo.

PS, Did the coyotes come last night.
