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?
The problem is the used car market still hasn’t recovered from the pandemic upshot. Prices have come down some but not nearly as much as they should.
If it’s burning oil that means it’s getting too hot. That’s not okay, and this seems like it might be a loss if it’s got an electrical problem eating headlights.
Electrical issues like that can spread and I wouldn’t want to someday upen up the fuse box or ECU and see something has melted. The newer the car, the more electronics it has for everything, and honestly that just means more parts can fail in the event that it’s already got an electrical issue.
I had an 05’ mini cooper base model. The radio wouldn’t shut off like it should or would turn on by itself. It burned up the 30 pin apple connector you’d connect your phone to. It eventually started having other issues with the electronics (tail lights that were always on (even the third brake light), etc. It also had transmission issues (which I don’t believe were related to the electrical problem, but to a recall that requires the transmission be rebuilt). It made it to 130k miles before I sold it (to a used car lot) but only just. Oh. And the hazards stopped working.
Never had engine problems with it but the electrical and transmission issues made it too expensive to fix vs buying a new (used) car. My brother put a junkyard engine in an older focus and right now that’s my daily driver while we rebuild my other car.
If it still runs and it’s not showing symptoms just do the oil changes more regularly, and fix what you think is reasonable. But think about selling it because it’s probably a ticking time bomb.
