Hello, Im in the same boat almost identical to schn0354, started doing it when i bought it at 125k replaced the engine with a low km used one at 214 KM ,same bullshit all over started at 1L every 3000 now at 246 KM its at 1L every 1000 KM using 15w-40 diesel oil.
Im getting ready to do something, haven't decided if im gonna go 4A-GE or rebuilt the smoke factory.
I have gone into it a little more, its all the oil control rings, nothing more, on my old original engine upon removal the rings were hopelessly stuck in there grooves, nothing i found would un-stick them. after removing the scraper rings they have no spring, but still maintain the proper end gap suggesting they haven't worn at all.
I have the same bald spot on the thrust side of the bore but unfortunately my engine is about .0005" over tolerance before honing so like .0010" after, besides that the piston skirts have moderate scoring so it doesn't make sense to reuse the pistons. The crankshaft has scouring because of oil starvation because of low oil...
Gotta start a 7A-FE Oil burning fan club..... theres alot of people out there!
