Almost fatal affair!

As for my great surprise early this morning when I started for flight, I recommended the warning lamp in the meter cluster of Caldina at the moment stopping at the railway crossing with a just a little bit nose rise up posture. The light on time was very short but I never miss the warning. Continuation of warning lighting means the reduction of motor oil pressure leading to burning out of the motor combustive room and sticking of cylinder and piston. Complete death of the 1AZ-FSE motor in worse case, the trans-axle might be destroyed together with!
I feel somehow ashamed to report about this with reddish face. So, the warning lamp of motor oil level is not just a warning but the motor is now coming to death in few seconds if it is not stopped immediately.
Lack of lubrication by motor oil causes the overheating phenomena between the moving surfaces everywhere inside of the motor construction, especially cylinder wall will be scratched by the piston rings producing irreversible decay also the small and big end of connecting rods will be torn into pieces. I have ever seen such a miserable motors destroyed because of lack of lubricating motor oil.
Miserable disaster was almost coming down on me, living in piece without paying attention on my Caldina with complete relief. How come? Motor oil was replaced few months ago at the Netz Toyota factory! Lack of motor oil amount and that of cooling liquid are surely different each other, the former the worse.
Why the amount of motor oil has reduced in relatively short period time? As no dripping mark is observed on the garage floor, the reason is not leaking or dripping by destruction of sealing in somewhere, but being burned in the combustion room, oil coming down from upper head portion such as from the space between valve stem and valve guide or oil seal around there. Oil rise up to combustion room is caused by some space on the oil ring outer surface?
In addition, inconvenience on the Automatic front corner pole, a flexible controlling lac guide fell down today, urgent repair ceremony is required ASAP. Anyway, these days, troublesome affairs happened on my most favorite vehicle.
