I don't have pictures. I'm not mechanically inclined so I took the vehicle to a trusted mechanic and he did the borescope that was suggested here.

Of note, prior to the coolant loss becoming a major issue, I used Seafoam in the crank case prior to the last oil change to try and mitigate the oil consumption. Consumption went from a quart every ~700 miles to a quart every 1,000 miles. And the engine ran with less vibration at idle as well.

Not sure how Seafoam compares to the BG product.
