Top of piston head (cylinder 1)
 

I had a misfire from cylinder one and currently and in the process of cleaning and rebuilding my fuel injectors so out of curiosity I decided to get a camera and check out the piston in cylinder one but the problem is I have no clue what to look for but I did manage to get this picture and I cant tell if it is carbon buildup or what, the reflection of the led doesn't help.

Thanks for the help

I can't see anything in that pic to say if there is an issue or not.

I will try to get a better picture
 

If you can enlarge the image that is the very top of the piston you can see the edge of it at the bottom

I'm with turbo, for some reason that image is extremely low resolution. Maybe your camera was set on the lowest setting or maybe you saved and posted just a thumbnail instead of the actual image?

Even enlarged full screen on my phone I can't read the words printed on the tool, much less try to figure out what the image on the screen is showing.
