rattle sound cold start

[marky]

When I start my car in the morning after like a min or so of warming up I hear a rattle or something but goes away after.. I hear for like less then a min or so then its gone.. I have good oil.. I did notice that I was empty on my coolent on the little tank so I filled it up half way and I took it for a drive and it was full.. must of needed to cycle. .

But yeah I only hear that for a bit and never hear it again after driving/idle.. must be the cold early morning starts.. anyone else get that sound? Ill try to upload a video later on ..

Do you have an aftermarket header or any other exhaust components? My gasket from the header to overpipe was causing an intermittent rattle because it wasn't torqued down evenly. Loosening the front pipe mounting bolt before tightening the joint along with some ultra copper RTV sealed it right up. If you've got the stock header, it could be the heat shielding around it. Check to see if anything has fallen down onto it. Last time I jumped a friend's car, I noticed the positive battery cover had fallen off and was laying on that heat shield.
