I use assembly lube on the camshaft and lifters only. Mains and rods get fresh clean engine oil. I like 30 wt valvoline if an older motor. Late models with tight clearance, use mfr recommended. I dunk the assembled piston, rings and rod in a can of new oil, let me soak for a few minutes, then load em in the ring compressor and install em. On the rod bolts, slip a length of rubber fuel line over each rod bolts, maybe ten inches long. This helps line the rod up so you do not nick the crankshaft. Keep the bearing dry if you are going to plasti-gage the clearance on the bearings. Lube them after gauging. Mains the same way. I pre prime the oil pump off the motor with oil before installing. Then prime the motor before starting. Keep everything clean!!!!! Check you end gaps on the rings before hand also.
