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

have had water pump, oil valve separator & clutch replaced over past year - now getting a "whirring" sound at idle or when off the gas. gets quite loud. i have a quick 8 second video but cannot upload. any suggestions?

POST 2Original post

Serpitine belt replaced too? OE Porsche water pump? Remove the belt. See if noise goes away. If it does, isolate the noise. Maybe a pulley?

POST 3Original post

Check alternator.

POST 4Original post

check everything driven by the belt . does the sound change when stepping on/off the clutch pedal ?

POST 5Original post

As said- Remove the serpentine belt and spin each belt accessory- attempt to recreate the sound. Replace the offending item, reinstall serpentine belt.
