Every mechanic and service desk guy I've talked to who's been around the
V6 for any length of time has said that you're on borrowed time over
60k with the timing belt. They've all seen belt failures, pump seizures
and tensioner failures which have wrecked motors.

My water pump starting making chirping sounds around 58k or so. I ignored
it but was lucky: somewhere around 63k I had everything replaced. Around
61k or so, I took off the timing covers to take a look around: no leaks
from the pump, belt looked okay, etc.

So, emperically, eventhough this stuff may _appear_ to be okay, it really
_won't_ last much longer...
