For my two cents worth there are three possibilities for option 1 that I've been looking in to:

1) Secondary Air pump that kicks in for 30 seconds but only on full cold starts.

2) Bendix (hope I spelt that right) spring on starter.

3) Cam chain slap.

Number 3 is what has me concerned. It can occur on a cold or hot engine. I do occasionally get it, but people say that it too is somewhat normal and can be reduced by using different oils or replacing the cam chain guides.

FWIW, my starter does sometimes have the squeal and I do occasionally her the cam chains. I don't worry about the squeal and when I crawl underneath it I'm going to see about removing the starter and spaying or greasing the starter shaft to see if that alleviates the squeal. But the cam chain noise worries me. It is just occasional, but it worries me. If/when I have the clutch replaced, I'll get the IMS replaced, and at the same time will replace all of the cam chain guides and possibly tensioners too.
