Ive always done that, I really thought everyone did it. I want to see how everything is getting oiled, and also no matter how clean people try to be with clean oil there always seems to be that first shot/hint of slightly discolored oil and since im not really cranking the motor other then to get it fully primed I use a few paper towls to soak iy up out of the lifter vally.
Thats why im not big on assembly lube other the on the cam.
I think after seeing the issues with my son small block I will now be priming every engine I build before I install the intake manifold. Big and small blocks.
