The pics are a bit grainy/blurry but it was a $30 borescope that I've never used before. The videos for whatever reason didn't record properly or I would have more to show of the cylinder and crosshatching condition, which both appear to be in great condition. 172,xxx miles on the vehicle at the moment. I use top tier gas, the occasional bit of PEA treatment and MMO now and then. Only synthetic with extended drain intervals. Burns no noticeable amount of oil. Idles smoothly. I would like to remove that carbon from the piston tops though.
