Noise in engine bay

[Vp stocko]

I have a 93 vp commodore, when the engine warms up i can hear a wistling sound coming from the left side of the motor, cant exactly hear ware it is coming from..

U can only hear it when motor is warmed up

Does anyone know what it could be

[monkeys437]

Maybe a vacuum leak from a manifold gasket or something. Could be the belt or pulleys too

best you can do is get a bit of hosepipe, one end to your ear, the other poke it around the motor and try to localise the sound. as said before, could be vaccum leak so check all your hoses

That being said my motor whistles/hisses like all hell under labour, but not at idle.
