When the car had 33,654 miles (3,498 miles since the previous oil change)
the owner, R. Nayar, took the car to a Toyota dealer complaining "the engine oil light
flashes on and off". The dealership found "the vehicle has approximately
1/2 quart of oil inside the engine" and that the "inside of the valve cover
is black" and that the "dipstick is also sludged up."

So we are dealing with an owner who drove 3,498 miles without checking
the engine oil level. The oil level got so low the engine oil light flashed
on and off, signaling dangerously low oil pressure. R. Nayar STILL did not
check the oil level and STILL did not stop driving the car as instructed to in
the owners manual. Instead, Rahul Nayar continued to drive, including
driving the car to a Toyota dealer which found only 1/2 quart of oil in the
engine - a catastrophically low amount of oil. With such a tiny amount of oil
in the engine the oil was overheated and turned to sludge, just as it would
in any car. So by 33,654 miles we are dealing with an engine that suffered
severe mechanical wear, such as connecting rod bearing wear and fatigue
due to the ultra low oil level and an engine that had sludge, due to the low
oil level, that could have blocked or partly blocked critical oil supply passages
and holes in the engine.
Now amazingly, this damaged engine still survived almost another 20,000 miles
- to 51,888 miles - before a connecting rod bearing finally gave up and the
rod tore a hole in the side of the engine block - such holes are a classic symptom
of oil starvation due to a low oil level. Now even when the Toyota dealership
informed R. Nayar back at 33,654 miles that the engine was almost empty
of oil, he still apparently did not take personal responsibility for regularly
checking the oil level and still continued to drive the car despite ominous engine
noises. How do we know R. Nayar STILL was not checking the oil level inbetween
oil changes? Well he admitted it on the old Corolland forum. Also, he had
several oil changes done at a Fix N Go shop after the 33,654 mile oil starvation
incident and did not notice that fix n go had wildly overfilled his engine with
5 quarts of oil each time http://www.saber.net/~monarch/fixngo.jpg when only
3.5 quarts are needed to bring the level to the Full Mark on the engine oil dipstick.
In summary, Rahul Nayar did not check his engine oil level inbetween
engine oil changes every 3,500 - 4,500 miles. He made approximately
10 -15 stops for gas during those miles yet failed to ever check the
oil level. The owners manual recommends checking the level at EVERY
fuel stop. The bottom line is Rahul's engine would not have been destroyed
if he had monitored his engine oil level as instructed in the owners manual.
Therefore it isn't fair to ask Toyota to cover the $4,500 worth of damage
to his engine. Even Rahul's new engine could fail in the same way if he
continued to fail to monitor the engine oil level at a reasonable frequency.
