Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

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

POST 2Original post

did you try opening the engine lid and listen for the sound to maybe pinpoint the location?

POST 3Original post

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.

POST 4Original post

supercharger.... maybe a pulley, or an AOS, a crack in some hose like the oil fill tube... video the whistle and post
