If you had well over 300k km and it had a hard life (traffic, tough climate) then burning that oil would be considered expected.

When my engine gets to that point i'll be tossing in a 2zr but I have 155k km on my engine and zero oil consumption. That is with an engine driven hard but meticulously cared for and 13k km oil change intervals on 0w30 synthetic (as per a used oil analysis).

I don't expect to be seeing any oil consumption until. Well above 250k km.

Remove the PCV valve every oil change and spray it clean with some brake or throttle body cleaner so that it rattles freely when shaken.

Mines done 110k miles. So that's like 165k KM?

I checked the PCV valve just out of curiosity. It was removed and cleaned for the service last year. It was still clicking. I don't think it was blocked. Cleaned it out with some brake clean anyway just to make sure.

All Toyota engines burn oil. Mine has been pretty well looked after. Oil changes with the yearly 10,000 mile service. It does do a lot of motorway miles which I not sure the 1KR engine was really designed for. My sisters Yaris with the 2SZ burns oil at around 1 litre every 2000 miles. Its only done 60,000 miles. She's only put 10,000 on it in two years.

In any case I just plan to drive mine till the engine blows up or until its burning a litre every couple hundred miles. I might do an engine swap or a quick and dirty rebuild.
