Tighten 115-C connecting rod bolts dry or oiled?

Not too shy to talk

I have gleaned from this site that the proper torque on the connecting rods of a Packard 115-C should be 45 to 46 LB/FT, but should they be dry or oiled? Also, should the nuts on the head studs be dry torqued? Thank you.

Dry, both.

My Motor's Manual indicates 55-60 lb-ft for the 6-cylinder connecting rods, 45-50 for the Super Eight.

Home away from home

Double check the rod bolt torque to the Packard specifications! I once torqued mine to a 1956 Motor's Manual but the postwar sixes used larger bolts than prewar so using the specified torque on my smaller bolts, they stretched and had to be replaced.

All generalities are false.

I didn't check the 1937/1938 Shop Manual but for the 6-cylinder in 1939 Packard gives 715-725 inch-pounds,or about 60 ft-lbs. That's good agreement with Motors for prewar Sixes.
