Grant-

I may be swimming in water that's too deep, as I don't know everything
about harmonic balancers. The other hand, I have read and practiced quite a
bit on balancing and silencing motors, so I hope this helps.

The flywheel, counter-weighted crank, and reciprocating parts in a Jetta
motor are *supposed* to be balanced as a unit. The intermediate shaft,
which counter-rotates (opposite the crankshaft), acts as a torque
damper/balancer. If your motor has a buzz at a certain speed, you may have
some parts out of spec. Every H20 VW I've driven was smooth as silk all the
way to redline...

I've been reading up on harmonic balancers and I think
that one of these on my Eurospec motor might kill the
"buzz" at 3500-400 rpm. What does the list think?
Has anyone heard of a harmonic balancer for a Jetta?
