engine strange sound
My friend called me yesterday and he said i have a strange problem with my Porsche.
He is the owner of a Boxster 1999 and the problem is......
Once the engine is getting warm when he depress the gaz pedal he can hear like a whissle sound comming from the engine and more the engine get warm more you can here the sound...
He said the engine run perfectly well except for this whissle sound
Any idea folks
Thanks

Maybe the Air Oil Separator -= AOS?
Can he take off the oil cap when the engine is warm and running? Often when the AOS goes bad there is a whistle sound and a vacuum is created in the crankcase that will make it very hard to remove the oil cap.
