Hello again to this great community!
I decided to write here for an issue im having lately. My 2.7 (2003) boxster engine is doing a "knocking" sound on idle.
About the noise:
- Almost Irrelevant if warm-cold engine.
- It Reminds me of a diesel engine car sound (
)
- No CEL or anything related, spark plugs/coils/oil new
Only thing im a bit guilty is that the sound started happening when i switched to 95 Octane, but maybe its irrelevant ?
No idea of the Serpentine belt condition by the way.
Thanks to All!
