So I finally got an endoscope & poked around in cylinder #2, which had the sudden loss of compression.
There seems to be a large gouge in the cylinder wall of #2, but I'd like to confirm with you guys that it's not something else (optical illusion, whatever)
While I was at it, I also took a peak at cylinder #1, and noticed a couple bright spots on the piston head-- one towards the center, and another right on the edge. The bright spot on the edge of piston #1 is reflecting onto the wall-- the walls are actually fine.
What do you guys think based on these photos? Do I have definite damage on cylinder #2 that will require pulling the bottom end of the engine?
