Nothing wrong w/adjusting the lifter preload w/the engine running, other than it's messy.
Hopefully the lifter and cam lobe isn't trashed. Over-the-counter motor oil can cause problems at cam break in time if there's no break in additive used like ZDDPlus, or if an engine break in oil isn't used. The lobes and lifter bottoms should also have been covered in moly break in lube.
But even then sometimes stuff happens and a cam/lifter will fail- sometimes because of idling the engine before the cam is broken in or because the lifter didn't rotate.
