MY17 Caprice (LS3)
My engine often makes a sound a bit like maracas when it is first started, after it has been left off for an extended period (e.g overnight). The noise goes away after a minute or so, and the engine is then very quiet. It has been to a performance shop, who replaced all the lifters. I initially thought the noise was gone, but it's still there. (not sure yet whether there's been an improvement - at the moment I think there probably has been, but not 100% sure).
Pay particular attention at about 40 seconds in to this recording:

As a matter of courtesy, I have been discussing this issue over here: http://www.ls1.com.au/forum/showthread.php?171325-LS3-Rattling-sound-when-stone-cold
The reason I am posting here is that no-one offered an opinion on the recording. (and I'm also embarassed to have to admit that the problem is still there ;^) ;^)
