Hello all,

New to diesel and more specifically Duramax LLY. 2004 GMC 190k miles

Took the oil fill cap off with engine running and you can hear a slight high pitched metal ringing/rattle noise. This is regardless of engine being cold or warm. Any ideas? Would appreciate if anyone could see if they have the same noise. Thank you

Welcome to DieselPlace
You may be hearing the "Typewriter tick" of the Duramax.
The noise you hear is normal for the Duramax Engine
