It won't lube everything. Many parts, including the cylinder, pistons, cam lobes, accesory gears, etc. are lubricated via centrifugal splash from the crankshaft (specifically oil fed to the rod journals) rotating at 1000+ RPM. Acc gears get splash from the oil fed to the idler gears and then slung to the other gears via centrifugal force, as well as a bit of splash from the cam gear which it gets from the aft cam journal .

There is a reason that all engine manufacturers use fogging/pickling instead of recommending approaches like this.
