There is an ongoing issue with these cars when they go over 100,000. The oil control rings seize up due to carbon buildup. As the carbon builds up, it prevents the rings from spinning around the circumference of the pistons as it moves up and down in the block. That, and the high possibility of weakened valve seal operation due to hardening. The recommendation I have for you on this issue is to change to an engine oil that is specifically formulated for 'high mileage engines'. This particular motor oil has additives in it that soften the valve seals, which restores their ability to control oil, and will loosen the carbon buildup on the oil control piston rings. Changing the oil every 4,000 KM would also be recommended when switching to this motor oil.

I was hoping it could be a PCV valve. so what brand of oil do you recommend? can I just use additive to a common oil? and lasttly... could these oil control rings be easily replaced?
Expert:  Toyota Service replied 1 year ago.
A PCV valve does not cause the engine to burn oil. The only way oil gets burned is when it gets into the combustion areas on top of the pistons where the fuel mixture ignites. Any brand of oil is OK, as long as it specifically states "Specially Formulated for High Mileage Engines" on the label. I would not use a generic additive.Regarding ring replacement, this is a job that requires the engine to be removed form the vehicle. Replacement of the rings would be considered part of a complete engine overhaul.

so using this oil for how many cycles can usually make them work again ?
Customer: replied 1 year ago.
and actually when I say BURN oil I don't mean I can see it from the exhaust.. I havent observed it to clear this out be honest.. I just saw that level of oil goes half way after just 1000 miles 1600km or so
Expert:  Toyota Service replied 1 year ago.
That depends on the severity of the situation, which we cannot tell without taking the engine apart. Under medium conditions, it would take about 4 to 6 oil change intervals to start to notice a decrease in oil consumption. If the oil is not leaking out onto the ground, visibly, the oil is being consumed ('burnt') by the combustion process.
