Whenever I start my cold engine there seems to be a clanking noise...

Anyone know if this normal or at least not dangerous?

Doesn't make the noise when it's warm, not to mention it also cranks and idles a bit better... I think I still may have a minor vacuum leak (although I compensated for it by advancing the timing a bit).

 

If your car runs and idles fine it could be just a loose or bad exhaust hanger,bad motor mounts,something in the engine bay resting on something it shouldnt be?pop your hood and have someone listen and check around.If your engines running fine it could just be external.
