high-pitched hissing noise
hey guys I have a lil inquiry maybe someone over here can help
whenever i manage to turn on the car in the evening I get a strange high-pitched hissing sound from the engine, this sound ends when the engine completes its warmup. Is this normal or should I have a mechanic check it out. Although the car had a fresh oil refill and engine flush a few weeks ago (8 litres of Mobil1 Synthetic Oil) and our infernal summer's nearly over at this end of the globe, could this have to do with anything yet??
BTW an air filter replacement is overdue
