Nissan Maxima: Camshaft Failure

How did the camshaft fail exactly?

The camshaft was not removed from the car but the failure is inside or
just beside the first bearing closest to the timing belt/pulley.

It's not their fault. The engine oil passage feeding oil to the cam bearings
plugged up and the cam seized in the engine.

Right, makes you wonder what the oil change interval was.

I'm sure it missed a few. One thing people don't consider are the hours an
engine runs. In stop and go - traffic jam type use, 3000 miles is WAY too
long to go between oil changes.

I always thought cars should have an "hours" meter. Some of the european
cars use a variety of ECM data to indicate when to turn on the "change
oil" indicator. That's probably more reliable than a static # of miles.

The car had the oil changed every 5,000 miles or less when I used both
Mobile 1 Synthetic or later regular Quaker State oil. If my memory is
right, the manual says to change every 7 or 8000 miles. Is lack of
oil the only reason the camshaft would fail? Normally lack of oil
would cause the bearings to fail and stress would cause a shaft to
fail. This is in the aerospace world - perhaps different in the auto
world. Camshaft failures on the Maxima engine are rare so if it was
oil related I would expect to hear about more of them. I'm favoring a
rebuilt factor engine rather than repair the existing one.
