Volvo 440 Whistling - Ken
I own a 1994 Volvo 2-litre automatic which has done 65,000 miles and is serviced regularly by the local Volvo dealership. It has recently developed a loud whistle when first driven from cold. The noise comes whilst accelerating and continues until the engine warms up (5 to 10 mintes), it then stops and the car runs normally whilst the engine is warm. Any ideas?

Hi Ken

could be a leak on the inlet side of things, I had a Renault 5 which whistled, had me baffled until on day I leant on the inlet manifold after starting to have a look around and the whistling stopped. A quick job tightening up all the connections at both ends stopped it.

as ever

The whistling is probably caused by an air leak on the inlet side of things
An obstructed idle air bypass valve could be the cause?

Manifold gaskets are a favourite cause of whistles as Mark found out.
