I have a 2001 Dodge caravan. When I start engine in the norning,it very noisy engine about 10 second depend on the weather it is more noise when it colder and less noise when worm weather, It will make noise only one time a day. After started engine about 30 second I turn of and start it again now it sound normal ( I living in San francisco) I learn and have some experienced car repair, I try to find and think what cause that noise for many months and I still no anser.

I think what you are describing is low oil pressure noise until the filter re fills with oil, some cheap oil filters drain back over a few hrs and when you start up you can get a bit of bearing noise until the pressure builds up, fit a filter with an anti drain back valve.
