So I've been experiencing an intermittent high pitched squeal coming from the engine bay but I can't pinpoint exactly where it's coming from. Sounds like charge pipe side but sounded lower.
I removed my left intake and both charge pipes thinking it was cracked but no damage or cracks and all seals were secured.
If it was an air leak, it would be consistent. If it was a belt or alternator we would hear the grinding. But it happens cold hot idle and under power.
Thoughts?
