<VV> FC Engines - Harmonic Balancer or not?

They don't typically fail "all at once".  There is usually some warning - 
such as fan belt won't stay on.  Time to inspect!  If you miss that one, you 
still get the "slices the side of the oil filter" one.  Now, if you've not 
figured it out by that point, you need to stop driving Vairs.

Later, JR
