Bongo Fury

Driving home today noticed a hissing sound coming from passenger side rear, Not sure just where it is coming from as only hear it when vehicle is moving sound is not constant, more intermittent Any ideas please.

No idea - unless you've lost your pet snake

Manifold stud broken?

It is not a screeching sound Wayne, more like a leaky airline

I would check your hoses.
I had the exact noise in my Bongo. Turned out to be a small hole in one of the hoses.
Best to check it out.

I will do, was raining hard when we came home, so will check level of coolant now all has cooled down

Coolant level fine

do you check the pipes conected to the turbo Pete?, can you here it on idle or just when you put your foot down?

Have not checked turbo yet Wayne, will do it in daylight Did not hear sound when stationary and revved engine, just when running low revs when moving,

leaky valve in a tyre?
or stone in tyre as that can sound the same ?

you've been bongod

Cheers Carl have been parked on gravelly carpark, tyre pressures are fine, so will check trye treads in the morning, thanks for the prompt helpful responses(and the funny ones too )

Is it a wooshing sound just before it changes up gear?
Really advise you to check your hoses when the engine is running.
I ignored the sound for a while, then i noticed it was loosing coolant and that turned out to be quite costly.

Hi,
Maybe window not closed fully,or,door rubber not sealing properly.Just a thought !!

It is an external sound, will check hoses been there with the costly leaking hose before
