The cold start rattle may be more due to a lack of oil than cold. My cold start rattle was due to a broken rear guide assembly. Even aften replacing all of the failed camshaft timing components the engine still rattled at cold start for a second or two. I eliminated all cold start rattle by installing a pre-oiler. The only way to know with certainty the source of your problem is to visually inspect.
I was listening to it again this morning. It really wasn't nearly as loud as I remembered (I work on the river for 28 days and just got back a few days ago). I wonder if anyone has had any luck using oil additives/stabilizers to help quiet the noise? I realize it wouldn't be fixing the problem, only addressing the symptom. However, if it worked, it could help confirm what the problem is before you go yanking motors and junk.
