Down the plug hole, the glow plug hole.

Hi All,

This is the results of a recent internal borescope examination of the engine in the SVDP BMW 120D race car. I am putting them up here more as a photo dump as well much as anything else.

The image quality overall seems poor, however, on the camera while you are looking around inside the cylinder the image quality seems much better. The video helps but still not as good as you see.

This is the video.
You are traveling down through the injector hole (glow plug hole is to small).  You will see the liner passing top left to bottom right.
