On the counterweights, I don't understand how you can "see" if they're a problem.

I feel so sorry for the guy - he obviously is not getting what he is entitled to out of that car.

As you point out, depressing the clutch would isolate the transmission and clutch disc.

Wouldn't resolve the question as to what may have been fouled up on either the clutch plate or flywheel.

Sad to report I have seen more than one Packard crankshaft butchered / ruined by well-meaning but mis-informed machine shops. A "pounded out" crankshaft on a "Senior" Packard is not that unusual - overly worn out rod bearings, coupled with all manner of abuse, will do that.

Obviously, new connecting rod bearings cannot be fitted; are of no use unless the crankshaft journal is restored to "at spec" for roundness.

As you are aware, "Senior" Packard crankshafts (both EIGHT, SUPER EIGHT and TWELVE have huge counter-weights fastened with #8 bolts - these bolts must be ground out to get the counter-weights off the shaft. Because the counter-weights are so huge, over-lapping a portion of the crankshaft "journal" today's crank grinders cant get in to re-surface the journal until those counter-weights are removed. A visual inspection would, as you infer, would only disclose the most obvious "butchering".

Yeah - this guy's symptoms, not that he is being clear, dosnt sound good - now that we have a more accurate description of the symtoms, I cannot recommend driving that thing at all until this is resolved.

I have a bad feeling this will not be resolved without a complete tear-down and re-balancing of all of the engine's components. Wish I had better news.

It frankly infuriates me when I hear about a Packard of ANY series that dosnt deliver what Packard cars are so famous for...(again, if they havnt been brutalized.)
