Good advice from the list as always.We drove it to work
today, and the attention from co-workers and customers was
pleasing. The rear pinion no longer leaks, Barry said the
old seal practically disintegrated in his hand, and the
pinion shaft had miniscule wobble.
Our problem with timing is that the previous owner must have
replaced the oil pump but neglected to line it up properly
with the distributor. The #1 terminal on the dist cap is off
180 degrees. Tomorrow, we will set the engine to TDC, remove
the dist cap, remove the oil pump, turn the dist rotor so it
points where #1 really should be, then install the oil pump
properly. Theoretically, timing shouldn't change, only the
point of spark.

manifold cracking (been there, done that).
