My friend has an 04 gto 6 speed...he said when he cranked it this morning that it clattered real bad and sounded like he was throwing a rod...said as soon as it warmed up it went away...any ideas as to what's going on? Had been sitting about a month so it may have lost oil in the heads but it did it again later that day after it had been driven about 30 miles and let cool all the way down...any help would be appreciated!

Dunno...my car doesn't do it...but who knows...is there anything harmful going on or just something the us ls1 guys have to deal with?

It's just the nature of the beast. Mine does it. And no, it won't hurt anything. It's just really annoying.
