Again I use Marvel Mystery oil on the pistons for assembly and I use it on all machined surfaces to prevent rust between cleaning and assembly. WD-40 (water displaceing film #40) is just a thin (very thin) film and cannot lubricate for very long and take any pressure applied against it (That's why I only use it on squeaky household door hinges). You should use a lite weight engine oil or trans fluid at a minimum for all parts in an engine. I use Moly-B grease for my assembly lube in bearings,cam,lifters,etc. and change my filter and oil after 20 minutes. 16 Motors and no problems with this practice.
