Sorry for the bad image quality.
The image is of the top of piston 4 and the cylinder wall in a Toyota 2AR-FE with 162,000 miles. All Toyota recommended maintenance was performed throughout the engine's life. I have the feeling those recommendations were written by marketing people and not the engineers.
Based on what the image shows, the engine needs a short block. Am I correct?
Apart from the preeety picture, are there any actual problems with the motor? If not just drive it. Add zunc additive to every oil change from now on.
