Anyone got any suggestions on how to pre-oil
a Lyc. O-320 before its first run?

If it's the first run after overhaul, then the assembly lube should do
its job. If it's new and has already been test run, then it's the lifter
faces and cam that might be dry. I think you're 'sposed to get it up to
splash speed immediately after starting to minimize the scuffing.
There's probably a good recommendation at the Sacramento Sky Ranch site.
