General Advice on Mazda 3
 

Hello All,

I've recently bought a second hand Mazda 3 TS2 Diesel, I've just opened the bonnet and it isn't a pretty sight! Please see the attached pictures and comment with your thoughts on what could be wrong?As I was driving it home a half way on my journey a small puff of white smoke came from the exhaust (I thought this may be because it has been sat idle for a couple of weeks) But when I got home I checked the engine and it was very very hot (however the temp gauge didn't indicate anything wrong)

Thanks in advance! Please no sarcy comments.
(I hope I've attached the pictures correctly/see links below)

Image 1 is of the plastic engine cover right? Mine has some white fiber insulation material, probably a fiberglass or cotton mix, not sure what it is.
