these pictures are completly unedited apart from resizeing by imagestation

what you are looking at here is my exaust manifold however the camera didnt capture the color very accuratly in real life the color is much more orange and actually projects so as to light the back of the radiator
and here is the same picture witout flash which came out in blue for some very odd reason but shws some of the hottest areas very well

so i dont think theres much question remaining as to why ive got to change my lamba sensor as its the piece in the picture screwed into one of the hottest areas
