Lets play a game - What is causing my oil consumption?

Yeah, I wasn't giving two f**ks for the ring running around the bore. I was looking at the vertical scratches running up and down across the hatch marks.

Now that you mention it I can see those too. More subtle. The lighting and low resolution makes it hard to assess super well what's going on but what is visible is bad enough to pull the motor.

Tear down before more damage, might just be an incorrectly installed ring or so and hopefully everything is salvageable.

Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank. 

In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine.

I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied.

Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice. 

Goddamnit, I would really have preferred this not happening.
